Abstract:

In the article it is noted that when the age of physiological maturity is reached, most of mares do not go hunting because of genital infantilism. The authors' studies showed that in the group where the repair filly had a systematic communication with the vasectomized stallions at 36 months of age, the reproductive apparatus was well developed, there were no signs of genital infantilism. All mares were found at the age of 36–37 months, and they became foal, at the mares of the control group at the indicated age the sexual cycles did not appear regularly, signs of genital infantilism were noted. The authors note that the vasectomized stallion provides, normal development of the reproductive sexual system of the repair mares, the full formation and manifestation of sexual cycles. The use of vasectomized stallions allows for an early effective prevention of genital infantilism and infertility in repair mares. Dosed communication of fillies with vasectomized colts and sterile coitus during sexual development promoted the physiological development of the genitals and the full manifestation of the sexual cycle.

Abstract:

In the superfamily Grylloidea, the main trends in the evolution of the copulatory apparatus were probably connected with the transformation of simple membranous (hagloid) genitalia, characteristic of ancient groups of Ensifera, into a complicated organ with highly specialized sclerites for fixation of the female during copulation. This evolutionary process was probably accompanied by partial reduction and disappearance of paraproctal hooks or other external abdominal processes which may have been used by these ancient groups for female fixation. Sclerites in the male genitalia of Grylloidea appeared independently not less than four times: in Gryllotalpidae, Myrmecophilidae, Gryllidae and Mogoplistidae. This hypothesis, proposed by Gorochov in 1984, was one of the reasons for division of the recent Grylloidea into four families. Each of the first three families acquired sclerites in the male genitalia once, whereas Mogoplistidae possibly acquired them more than once: male genitalia of the tribe Mogoplistini are of the hagloid type, membranous; in most genera of Arachnocephalini (Mogoplistinae), in Pseudomogoplistes (Mogoplistinae) and in Malgasiinae, male genitalia have three types of sclerites which could have also appeared independently. Moreover, many sclerites of the male genitalia in Grylloidea are formed independently and have significant convergent similarity; this is why the nomenclature of male genital structures based partly on their function and position but not exclusively on their homology is simpler and much more suitable for descriptions and morphological investigations. This nomenclature is considered here.

Abstract:

The general trends of evolutionary transformations in the male copulatory apparatus of the lower ditrysian Lepidoptera, family Gelechiidae, on the base of functional morphological analysis are similar to those in the order Trichoptera. Evolution of the genitalia in both groups was directed to improvement of efficiency of mating mechanisms. It is found that one of the general trends in trichopterans, reduced of gonopods, corresponds to the main direction of valvae transformation in lower ditrysian moths Gelechiidae. These structures, being of importance in grasping the female in other groups of Lepidoptera, lost this function in some genera and they completely disappeared in most advanced groups of gelechiid moths. That phenomenon is associated with transformations of other structures in copulatory apparatus, which functionally compensate for the lack of valvae. Such functional analogues are found in the course of comparative morphological analysis of the male genitalia in both groups. Similar changes and similar traits of the genital appendages in both groups, trichopterans and lower ditrysian lepidopterans, can be considered as evidence of parallel evolution. The possible parallelisms as indicators of common evolutionary trends in transformation of copulatory apparatus within the two lineages, Trichoptera and Lepidoptera, having a common ancestor, are discussed.

Abstract:

We examined the post-embryonic development of the male and female genital apparatus of the brown spider, Loxosceles intermedia. The development of the genital apparatus for both sexes begins with the appearance of inner structures. In the male genital apparatus, formation of the testes occurs first, followed by differentiation of the duct, ampulla and vas deferens, and finally the formation of the genital opening and differentiation of the copulatory organ (secondary sexual characteristic). Similarly, the development of the female genital apparatus begins with the formation of the ovaries, followed by the appearance of oocytes in vitellogenesis, then the development of oviducts and uterus internus and, finally, the spermatheca. These data may be very important in further comparative studies on the development of the reproductive system of spiders.

Abstract:

Goal. Goat breeding is a promising branch of animal husbandry, which is rapidly developing. The scientific literature has little information about the essential features and differences in the structure of the genital apparatus of goats. With the increase in the number of livestock and selection work in goat breeding, knowledge of the characteristics of the reproductive system is of great importance. Due to lack of knowledge of the structure of the reproductive organs of small cattle, the effectiveness of artificial insemination decreases and inefficient sperm of producers is used, since the complex structure of the cervix of the goat is an obstacle in the artificial introduction of sperm. Therefore, considering the need for further introduction of the method of artificial insemination into practice of goat breeding, the study of the peculiarities of the structure of the internal genital organs of goats is timely and necessary. Materials and methods.The study of anatomical features of the structure of the internal genital organs of goats was carried out on animals of the Zaanen breed, imported into the village. Galaiki Tarashchansky district of the Kiev region from Latvia. The material for study was the genitals obtained from goats aged 6-7 years. After the slaughter and bleeding, the genitals were separated into goats. They were then placed in an enameled cuvette and measured with a measuring tape, ruler and caliper. The linear dimensions of the ovaries, the diameter and length of the uterine horns according to the large curvature, the length of the uterine body, the length and diameter of the cervix, the number and structural features of the folds of its mucous membrane, the amount of caruncle, their height and diameter were measured. As mentioned earlier, the development of anatomical and physiological basis for artificial insemination of small ruminant animals was carried out mainly on sheep. Therefore, we compared the size of the ovaries, oviducts and uterus in goats of the Zaanen breed of Latvian selection and, according to the literature, the results of studies of similar sheep organs were analyzed. As a result of the studies of the morphological parameters of the genitalia of the goats, the following data were obtained: the mass of the left ovary – 0,6 ± 0,06 g, the right – 1,1 ± 0,04 g: the length of the left ovary – 2,0 ± 0,06 Cm, the length of the right – 2,3 ± 0,04 cm. The length of the left oviduct was – 14,2 ± 0,16 cm, and the right – 14,4 ± 0,15 cm. Accordingly, the length of the left horn of the uterus was – 13,7 ± 0,63 cm, the right – 12.2 ± 0,75 cm. The diameter of the left horn of the uterus is – 2.3 ± 0,07 cm, the right horn of the uterus is – 2,8 ± 0,08 cm. The morphological parameters of the unpaired genitals of goats were as follows: The length of the uterus body was – 1,8 ± 0,15 cm, the cervix was – 5,9 ± 0,29 cm, the cervix diameter was – 1,8 ± 0,08 cm; the number of folds in the cervix is – 4,7 ± 0,50. The height of the caruncle is – 0,5 ± 0,06 cm, their diameter is – 0,7 ± 0,10 cm, the amount of caruncle is – 96,5 ± 1,70, the area of the caruncle is on average – 0,4 ± 0,10 cm2. Conclusions. As a result of the carried out researches the anatomical and morphometric characteristics of internal sexual organs of goats are given. These data make it possible to expand and supplement knowledge on the morphology of the reproductive system of farm animals, which must be taken into account in artificial insemination of goats. The data obtained by us are somewhat different from the results of the studies of other authors, but do not contradict them.

Abstract:

Traumatophoratriscalpta(Martens, 1875) is reported for the first time from the Tianmushan Mountains, Zhejiang Province, and its morpho-anatomy is described based on this new material. The genusTraumatophorais redefined on the basis of both shell and genital anatomy of its type species. The presence of the dart apparatus suggests this genus belongs to the subfamily Bradybaeninae rather than to the Camaeninae. This genus is distinguished from all other Chinese bradybaenine genera by the combination of the following key morphological characteristics: embryonic shell smooth, palatal teeth present, dart sac tiny with rounded proximal accessory sac that opens into a dart sac chamber, mucous glands well developed, entering an accessory sac through a papilla, epiphallic papilla absent, flagellum present. A comparison is also presented of Chinese bradybaenine genera with known terminal genitalia.

Abstract:

AbstractSEM studies on the cloacal opening of Oesophagostomum columbianum indicate that it is located on a raised conical structure called the “genital cone”. The genital cone is provided with a ventral lip and a pair of subdorsal gential appendages. The vental lip is a triangular structure having a single papilla on it and the genital appendages are covered with wrinkled cuticle with a nerve process projecting to the exterior in center. The bursa is supported by muscular rays which end up as knob-like sessile genital papillae. The inner surface of the bursa is porous. Spicules are two, equal, each provided with an ala which decreases in height distally and end up much prior to the spicular tip.

Abstract:

A 3-year-old Arabian mare underwent medical examinations due to the presence of abnormalities of the reproductive apparatus and stallion behavior (nervous temperament, aggressiveness, masculine attitude). During the clinical visit, an anovulvar distance shorter than normal was observed; moreover, vulvar lips were dorsally fused except for the lower neckline, showing a blind ending from which a penis-like structure protruded. The ultrasound examination revealed the presence of a cervix and corpus of a uterus, hypoplastic uterine horns, and small gonads with an echogenicity similar to a testis. Blood testosterone levels ranged from 0.4 to 0.6 ng/mL. Cytogenetic analysis showed a normal female karyotype (2n = 64,XX), while PCR amplification of SRY and ZFY genes revealed the absence of a Y chromosome. At necroscopic examination, internal genitalia arising from the genital ridge in the form of masculine type structures were found, while those deriving from the Mullerian ducts were of feminine type. In addition, an infundibular portion of the salpinx at the cranial pole of the gonads was found. This is the first case in equine species of DSD 2n = 64,XX SRY-negative, with the simultaneous presence of male (hypoplastic testicles, epididymal portions, and a penis-like structure) and female (cervix, horn and body of a hypoplastic uterus) genital structures.

Abstract:

Chronic pelvic pain is one of the most significant medical and social problems. The high prevalence of concomitant benign genital diseases in women of reproductive age are genial endometriosis, uterine fibroids, endometrial hyperplasia with common clinical manifestations, namely chronic pelvic pain, abnormal uterine bleeding, impaired reproductive function, and a high frequency of cancer pathology of the reproductive organs in young age that require a holistic approach to patient management and comprehensive problem solving. The objective: to investigate the proliferative and inflammatory activity of the glandular and stromal components of the eutopic endometrium (EE), the presence of nerve fibers in it as mechanisms for the formation of СРР in genital endometriosis in combination with other benign hormonedependent diseases of the genitals Materials and methods. The study involved 85 women with chronic pelvic pain due to genial endometriosis, uterine leiomyoma, endometrial hyperplasia, chronic salpingitis and oophoritis in various combinations, and 35 women by the comparison group with similar gynecological pathology without CPP. In order to objectify pain syndrome, a 10-point visual analogue scale (VAS) was used. Echography of the pelvic organs, the thyroid gland (if necessary) was performed by the Toshiba, Nemio17-pro apparatus. In order to study the molecular mechanisms of the development of CPP, the expression of ER, PGR, KI-67, VEGF, COX-2, NF in the eutopic endometrium was determined by immunohistochemistry. Results. The leading painful role in combined gynecological pathology was assigned to diseases in clinical group 1, which had the most pronounced algogenic anatomical and structural features. Formation of CРР is confirmed by the presence of rank correlations between the level of pain syndrome in VAS and immunohistochemistry characteristics with reliable direct connections of average strength with the ER (Spearman’s coefficient of correlation ρ =0.58; p<0.001), with PGR (p=0.42; p=0.021), with Ki-67 (ρ =0.55; p=0.004) and with COX-2 (ρ =0.42; p=0.021). Conclusions. The concept of the pathogenesis of СРР in proliferative genital diseases has been expanded. It is characterized by moderate expression of VEGF, high expression of ER and PGR, Ki-67 and COX-2, with NF in EE; which determines the development of СРР by the criteria being studied, both individually and in combination. Key words: chronic pelvic pain, proliferative diseases of the genitals, morphogenesis markers.

Some anomalies in the area of external genital organs have given rise to new embryological studies in recent years, which gave valuable data concerning the history of the development of the ano-genital area. The same data serve for a better understanding of the way of origin of some anomalies, among other things also anomalies, known as atresiae ani vestibularis, vulvaris, hymenalis, or better anus praeternaturalis vestibularis.

Abstract:

Introduction. Prolapse of pelvic organs is a polyethological disease, manifested by the displacement of the uterus and the walls of the vagina to the vulvar ring or out of it. At the base of this pathology, there is the functional inconsistency of the ligament apparatus of internal genital organs and pelvic floor musclesoccurring due to the impact of various physical, genetic, psychological, age, hormonal, iatrogenic etiological factors. Prolapse of the pelvic organs is an actual problem due to the high incidence of both reproductive and elderly women. This article considers the effectiveness of criteria for selection patients with different degrees of prolapse of the genitals for the implementation of surgical correction in conditions of the gynecological department of the municipal maternity hospital. Material and methods. The sample included patients with initial, post-hysterectomic, recurrent anterior and apical prolapse of the genitalia of II-IV degree according to POP-Q classification in the age cohort of 45-70 years who do not have systemic diseases, or with a compensated systemic disease that does not introduce significant limitations in physical and social activity. Depending on the severity of pelvic prolapse, patients underwent various types of surgical treatment. In 5 patients with incomplete uterine prolapse, there was performed laparoscopic extraperitoneal ligature hysterosuspension and vaginal wall plasty using reticular implants, and in the 1 patient with the complete prolapse of the uterus, there was made the vaginal extirpation of the uterus with extraperitoneal colposuspension vaginal walls plasty using a reticular implant. Women with adjacent gynecological pathology (24 patients) underwent laparoscopic (22) and laparotomic (2) operations for the main disease and the plasty of the vaginal walls (including 19 patients using reticular implants). In one case, a patient with elongation of the cervix and the lowering of the anterior wall of the vagina there was performed a modification of the Manchester operation using a reticular implant. In 3 patients with the isolated prolapse of the anterior wall of the vagina, the vaginal wall plasty was made with the installation of a reticular implant. Results. After the surgical interventions, no intraoperative, as well as early or late postoperative complications were noted. The evaluation of the effectiveness of the performed surgical treatment according to follow up in the period of from 12 months to 5 years, revealed 1 case of the recurrence of the disease in the form of cervical stump prolapse in a 58-year-old patient managed with succeed promonofixation of the cervical stump with a reticular implant. Conclusion. The high anatomical (94.4%) and functional (96.8%) efficacy of the surgical treatment of the prolapse of pelvic organs allow judging the persuasiveness of selection criteria for surgical correction of the genital prolapse in conditions of the gynecological department of the maternity hospital.

Full text

Abstract:

The importance of using copulatory characters in generic and higher taxonomy (not only in species taxonomy) is discussed in the light of the recent “genital clock” concept which should partly replace the old “lock-and-key” theory. This concept assumes that evolutional changes in the copulatory apparatus (if it is sufficiently complicated) follow after genetic drift, and that these processes occur at a more uniform rate than changes in the characters of external morphology, ecological properties and many other biological traits, since structure of this apparatus is less dependent upon the situation in the ecosystem. Evolution of the copulatory apparatus in the suborder Ensifera and in its ancestors may be divided into three hypothetical stages reflected in some morphological features: 1) a highly hypothetical stage without copulation and without a copulatory apparatus in the most ancient (extinct) orthopteroid insects; 2) the appearance of different organs in early Orthoptera serving for fixation of partners during copulation and for insertion of the spermatophore in the female genital chamber; 3) the development of complicated organ with consolidation of these functions.

Abstract:

AbstractSeven specimens of Xiphinema dentatum with abnormal genital organs were found in the same population. Normal females are amphidelphic with the vulva located slightly anterior to the mid-body. Of some 24 000 females examined, six were found to be abnormal. One has a normally developed genital tract, but located in an abnormally posterior position. Two females have two complete systems each, one system in the normal position, and the other well posterior. Another female has a normal posterior branch, while the anterior one is abnormally branched at the pars dilatata uteri into two oviducts and ovaries, one ovary being degenerate. Another two females lack central parts of the system, the remaining distal parts being fused proximally. Males are rare in this species, sometimes having a fully developed diorchic genital tract, but usually with only the copulatory apparatus developed. Of the 137 males examined, one has a normal copulatory apparatus, lacks the seminal duct and has two abnormal masses of tissue corresponding to the position where the testes would normally be located.

Abstract:

A new land snail species that represents a new genus is reported from Hubei, China. The snail has a conical shell with pits and/or granules on embryonic whorls and a smooth teleoconch with straight peristome. The head of the animal has a developed wart. The mantle lobe is only developed on the left side. At the front of the buccal mass there is no chitinous jaw that is without exception seen in Chinese camaenids. Its radular teeth are usually slender and tongue-shaped, not typical in bradybaenine snails. The genital system is typical of Bradybaeninae and is characterized by the absence of a membranous sac surrounding the terminal genitalia, penial caecum or flagellum; a well-developed penis sheath; a symmetrical dart sac apparatus; and one distally branched mucous gland. The new species Sinorachis baihu Wu & Chen, gen. and sp. nov., is assigned to the type species of the new genus, in which all the known Chinese Rachis species are included. Thereby, the new genus is composed of three species, namely Sinorachis onychinus (Heude), comb. nov., Sinorachis aureus (Heude), comb. nov. and the new species.

Abstract:

Sexual activity is one of the main goals of life on earth for every being. For a person, this goal of life is especially important, because, thanks to the mental development of his mental powers, his sexual activity is not instinctive, like in every animal, but is more conscious and therefore constitutes for him a more urgent need for life. Like any creature, human sexual activity is divided between two sexes, between a man and a woman, but the man accounts for only a small part of this activity, almost all the burden is borne by the woman. From this, the functions of the female genital apparatus are very complex: they are not limited to the narrow sphere of one genital apparatus, but relate to the entire female body, having enormous influence on other spheres of its activity.

The hook tip enters the genital antrum, nearly penetrates the proximal end of the egg string, and continues into a notch on the antrum wall. The apex of the egg string acquires a concave depression like the finger end of a glove. In this way the string is mechanically attached inside the female genital segment. The mobile ectoparasites Lepeophtheirus salmonis and Hatschekia hippoglossi have hooks which function similarly, but perforate the strings.

Abstract:

The Order Coleoptera provides good examples of morphological specializations in the reproductive apparatus, gonadic maturation, and allometry differing between the sexes. The female and male reproductive apparatus has been modified to ensure reproduction between individuals of the same species. The genus Cyclocephala has more than 500 species distributed in America, and Cyclocephala barrerai Martínez is an economically important species in the central part of Mexico. The objective of this work was to study the reproductive system, gonadic maturation, and allometry of C. barrerai. We used light, scanning electron, and laser scanning confocal microscopy to describe the reproductive apparatus and gonadic maturation of females and males. The relationship between adult weight and different parts of the body was established by linear regression. Regardless, the reproductive apparatuses of C. barrerai are like those of other Melolonthidae: the genital chamber, the type II accessory glands, and the ventral plaques of the female and the ejaculator bulb and genital capsule of the males are specific to C. barrerai. The gonads are fully developed when 18 d old. The weight of adult C. barrerai has a positive linear relationship with distinct parts of its body, while the antennae of males are larger than those of the females.

Abstract:

The Disorders of Sex Development (DSDs) are congenital conditions characterized by inconsistency among chromosomal, gonadal, and anatomical sex development. The aim of this research is to report the clinical and cytogenetic findings of four DSD cases and 13 couples of heterosexual twins in sheep. To this purpose, C- and R-banding techniques were used, and the analyses of the SRY (Sex Determining Region Y) and AMEL (Amelogenin) genes were carried out. Moreover, morphopathological analyses were performed in one case. The four DSD sheep cases were registered as females at birth, and for none of them it was possible to establish whether the subjects were born from heterosexual multiple births. Three of the four cases were diagnosed as XX/XY blood lymphocyte chimaeras, while the fourth case was diagnosed as a 54, XY SRY-positive DSD sheep. None of the heterosexual twins showed XX/XY blood chimaerism. This finding suggests that the blood chimaeric cases detected could also be due to a zygote/embryo fusion. Moreover, no gene variants involved in sheep DSD are known, the identification of which would be very useful for the sheep industry.

Full text

Abstract:

The genital ducts of Heterodontus portusjacksoni are lined by a ciliated epithelium. In the ductuli efferentes the epithelium is low and contains numerous intraepithelial leucocytes which often contain large dense bodies. All epithelial cells are ciliated and are characterised by apical vesicles, vacuoles and glycogen granules, some rough endoplasmic reticulum, dense bodies and lipid droplets, and a Golgi apparatus. The initial segment of the ductus epididymidis is lined by a very tall epithelium of ciliated and non-ciliated cells. The non-ciliated cells contain numerous apical vesicles, a large Golgi apparatus and numerous mitochondria and secretory granules in close association with an extensive endoplasmic reticulum. The terminal segment of the ductus epididymidis is lined by a low columnar epithelium. A proximal region, occupying part of the head of the epididymis, is similar to the epithelium in the ductuli efferentes. Distally, all the epithelial cells are ciliated. They are characterised by considerable dilated endoplasmic reticulum, a Golgi apparatus, apical vesicles, and numerous mitochondria and secretory granules. The secretory tubules of Leydig's glands are lined by a very tall epithelium with non-ciliated cells containing extensive, dilated, rough endoplasmic reticulum, a large Golgi apparatus, and numerous mitochondria and secretory granules. The significance of the structural differentiation of the duct is discussed in relation to the evolution of the mammalian epididymis.

Abstract:

The purpose of the study was to identify the structural features of the small glands of the vestibule vagina with some anomalies in the development of internal genital organs. Material and methods. Glands of the vaginal vestibule of 18 newborn girls with internal genital anomalies were examined histologically using light microscopy. The comparison group consisted of 10 cases of newborn girls without pathological changes in the urogenital apparatus. After separation of the vestibule from the surrounding structures from the organ wall, longitudinal fragments were cut out, which were fixed in formalin and, after posting on alcohols, an increasing concentration was poured into paraffin. Sections 5-7 microns thick were stained with hematoxylin-eosin and by Van Gieson. Craigberg reaction was also conducted. The digital data obtained during the study were subjected to statistical processing. Results. The analysis showed that, in norm, the small glands of the vestibule of the child's vagina at the time of birth are capable of active secretion. In newborn girls with anomalies of the uro-genital system, the thickness and area of the initial section, the number of initial parts, the area of the initial part on the cut, the number of glandulocytes in the initial part of the glands decrease. There is an increase in the lumen of the common gland duct. Conclusions. Normally, small glands of the vestibule in the newborn are fully formed. With anomalies of the internal genital organs, significant destructive changes in the glandular apparatus of the vestibule are revealed. In contrast to the norm, the initial parts of the glands on the longitudinal sections are deformed. The thickness and area of the initial section decreases, the number of initial parts, the area of the initial part on the cut, the number of glandulocytes in the initial part of the glands.

Abstract:

To date, the problem of genital prolapse remains relevant due to the high incidence of this disease. Prolapse today is becoming one of the serious problems of gynecology, attention to which is increasing every year. In modern domestic and foreign literature, there are quite contradictory data on the frequency of pelvic organ prolapse (from 4.5 to 30% in the population). In recent years, a significant increase in the number of patients suffering from genital prolapse has been recorded worldwide. It is known that not all women who have anatomical changes in the supporting apparatus of the pelvic floor seek medical help. This article discusses the prevalence of pelvic organ prolapse, identified by questioning and, further, confirmed during a gynecological examination. The questionnaire has a proven effectiveness in detecting the disease in its early stages. In the structure of complaints, according to the survey, more than half of women with genital prolapse (62.3%) noted urinary incontinence. Dyspareunia bothered 52.2% of women, pelvic pain — 48.3% of the respondents. The article presents a number of functional tests that provide early diagnosis of genital prolapse and the choice of an appropriate approach in the treatment of this pathology.

Abstract:

AbstractMany species of pulmonate land snails are equipped with one or more so-called "love darts". Even though the number and shape of these calcareous darts vary considerably between species, dart use has only been investigated in very few species. Here, we redescribe the mating behaviour of Polymita muscarum because previous reports did not include the use of the dart apparatus. Mating in this hermaphroditic land snail can be divided into three stages: courtship, copulation and post-copulatory activity. During courtship, full eversion of the genital atrium is reached, thus exposing the sensitive zone, genital lobes and dart apparatus. We observed that P. muscarum pushes the everted dart apparatus repeatedly onto different parts of the partner's body and does not lose its dart after stabbing. Dissected specimens had a single, slender dart with a round base, a broad corona and a circular cross-section. We propose that the morphology of P. muscarum 's dart is consistent with the idea of simple darts needing to be stabbed more often in order to increase the transfer of mucus, which contains a biologically active substance (i.e. allohormone) that enhances the chances of paternity. Besides adding to the growing diversity in the use of love darts in land snails, these findings contribute to the understanding of the evolution of this peculiar reproductive act.

Full text

Abstract:

A spermatophore is defined as a capsule of albuminous matter containing a number of sperm. Among opisthobranchs the families Retusidae, Philinoglossidae, Bullidae, Atydae and Runcinidae are all said to possess a copulatory apparatus which stores sperm and also forms spermatophores (Ghiselin, 1966). Relatively little information exists concerning the structure of the copulatory apparatus or the spermatophore in these groups and practically nothing is known about the copulatory behaviour of the animals and the fate of the spermatophore (Perrier & Fischer, 1914; Ghiselin, 1963, 1966; Thompson, 1976;Beeman, 1977). This paper will focus on the structure of the spermatophore of the cephalaspid Runcina (Kress, 1977). The formation of sperm occurs in the hermaphroditic glands, in a more central position than that of the eggs. These autosperm leave via the common genital aperture which is located laterally to the gills. They travel by means of strong ciliary action, through a seminal groove to the male copulatory apparatus on the right of the mouth. The sperm then moves through the penis and the prostate into a storage sac, the seminal vesicle. For copulation, these sperm are packed into a spermatophore which should presumably be introduced into the common genital aperture but which may be found attached to the mantle or foot, even to animals not yet sexually mature. We have taken this opportunity to study the spermatophore which otherwise might not be easily detected.

Butterflies of the genus Maniola are known for their large morphological variation, at the inter- as well as intraspecific level. Given the overlap in wing-patterns, habitat selection, and geographic distribution of various Maniola species, genitalia morphology is sometimes the only possibility to tell specimen apart. In this paper we describe diagnostic characters to distinguish different Maniola species by means of their genitalia. Included is also the first detailed description and illustration of the genitalia apparatus of the Sardinian endemic Maniola nurag. Further, we describe two Sardinian individuals with intermediate characteristics between Maniola nurag and Maniola jurtina, and propose that they are hybrids. Further, we shortly discuss the justification ofthe species status for the island endemics Maniola chia and Maniola cypricola.

Abstract Ditylenchus halictus n. sp. was collected as dauer juveniles from the genital region of adult males and females of the soil-dwelling sweat bee, Halictus sexcinctus (Halictidae), in Brandenburg, Germany, and cultured on the fungus, Monilinia fructicola. It is the first species of Ditylenchus to be reported in an active phoretic association with insects and is described and illustrated herein. Dissections revealed that 25% of female bees carried the dauer juveniles of D. halictus n. sp. internally in the Dufour's gland and/or seminal receptacle and/or genital region (range 1-193 dauer juveniles per bee), and 38% of males were infested in the genital capsule, copulation apparatus, and/or distal testes with 1-64 dauer juveniles. Morphologically, D. halictus n. sp. has six lines in the lateral field and appears closest to D. myceliophagus but can be differentiated based upon a combination of morphological characters, the mode of reproduction and molecular sequence data. Molecular analysis of the near full length SSU rDNA, D2/D3 expansion segments of the large subunit (LSU) rDNA, and internal transcribed spacers (ITS-1 and 2) and 5.8S rDNA support that this nematode species is unique.

Abstract:

Confocal laser scanning microscopy (CLSM) is a modern powerful technique that can be used for studying the externaland internal anatomy of arthropods. CLSM has seldom been used in acarology and very rarely for studying eriophyoidmites. It allows the capture of precise digital images of the fine details of external and internal chitinous structures, whichcan be further analysed using various computer programs. CLSM can serve as an effective tool for comparing closelyrelated and/or cryptic species, correcting diagnoses of poorly described taxa, studying immature instars, and particularly,for studying the structures and the functioning of the internal genitalia of adult females and males. In this paper, thepotential use of CLSM for the study of eriophyoids is demonstrated using specimens of 13 mite species and eight generafrom the families Phytoptidae Murray 1877 and Eriophyidae Nalepa 1898. This study showed that freshly mountedspecimens on microscope slides appeared to be the most appropriate for CLSM as older specimens tended to have reducedautofluorescence. The best choice for studying the external morphology and internal genital apparatus of eriophyoid mitesappeared to be the blue laser. Green and light blue wavelengths (488 nm and 532 nm) were found to be less useful. Thequality of CLSM images depended on the slide-mounting medium used. Among those compared, Hoyer’s medium wasfound to be the most appropriate whereas Heinze medium and media including Iodium gave poorer results. The empodiaand proximal parts of setae were shown to have very weak autofluorescence signals, but they reflected red (635 nm) and blue (405 nm) laser light, which could be detected with CLSM.

Traumatic dislocation of the penis is one of the rarest types of genital trauma. This type of injury is accompanied by a violation of the integrity of the skin and the penile ligamentous apparatus, with the dislocation of the penis into the scrotum under the skin of the thigh, or the area of the pubic joint. The low occurrence frequency of such injuries and the small number of observations described in the literature entails the absence of generally accepted treatment tactics for this category of patients. The article describes a clinical case of successfully treated traumatic dislocation of the penis with penile transposition into the pubic joint area and the formation of subcutaneous urinary leakage after late treatment of the patient for medical care.

It is also known that in case of uterine prolapse, in old and neglected cases, this method of raising the uterus and massage can give an amazingly quick and perfect result, in other cases it is not. Obviously, failure is the result of various anatomical relationships, and, according to the author, the bending of the uterus back and its side positions, where pessaries and surgical methods of treatment are more intelligent.

The taxonomic position of the genus Sitotrogoides is determined within the tribe Pexicopiini. The lack of the muscle m3 is suggested as a characteristic associating Sitotrogoides with Sitotroga and differing from all other genera in Pexicopiini. The type species of Sitotrogoides, Gelechia acanthopis Meyrick is redescribed. Our new records of Sitotrogoides acanthopis from Korea suggest its extended distribution out of Japan.

Abstract:

Cystoid tumors of the abdominal cavity, developed in one or another part of the female genital apparatus, sometimes give such a peculiar topographic relationship to the surrounding adjacent organs and present such pathological, anatomical, physical and chemical properties that seriously hinder the statement. Without dwelling on the generally known signs of mosquito tumors of the abdominal cavity in general, and in particular, on the distinctive signs of single-chamber and multi-cavity cysts, ovarian, parovarial and intraligamentary, I will allow myself to go directly to the question of interest to us.

Abstract:

ABSTRACTWe present the first specific record of a chironomid of the tribe Tanytarsini from early Eocene Cambay amber, India (52–53 Ma). The oldest known extinct tanytarsine genus, Gujaratomyia Giłka & Zakrzewska, gen. nov., is described on the basis of adult males of G. miripes Giłka & Zakrzewska, sp. nov. The species displays an unusual leg structure with unique leg ratios and tibial armature. The combination of the head and genital apparatus characters supports the hypothesis that Gujaratomyia and Cladotanytarsus are members of a common group within the subtribe Tanytarsina.
