Academic literature on the topic 'Cryptocephalinae'

Original descriptions and illustrations of the first instar larva of Megalostomis (Heterostomis) lacordairei Lacordaire and of Coscinoptera argentina Burmeister (Clytrini: Megalostomina) are provided. Based on the available information on first instar larvae, the tribe Clytrini is diagnosed. Unique of the larvae of clytrini is the antennal sensorium dome-like. Characters in common between Clytrini, Cryptocephalini, and Chlamisini (Cryptocephalinae) are highlighted, like the body J-shaped (in association with case-bearer habits); frons, clypeus, and labrum fused; spiracles with reticulate peritreme; egg-bursters present on mesoand metathorax, each situated anterior to a very long seta and a short seta ventral to these.

The comparative morphology of the prothorax and procoxae of New World Cryptocephalini was studied based on representatives of 11 of the 13 genera of the tribe. This study revealed a set of characters of obvious diagnostic and possible phylogenetic value supporting the currently accepted generic classification and two subtribes instead of the three currently recognized. Two general typesof prothoracies were found, the first occurring in Cryptocephalina and Monachulina and the second in Pachybrachina. Previously undescribed for Polyphaga, a monocondylic joint between the coxa and trochantin, was found in all the genera studied. Possible movement of the trochanter, including the transfer of advance movement into rotation, is described and illustrated.

This study revised the subgenus Burlinius Lopatin, 1965, of the genus Cryptocephalus Geoffroy, 1762 (Coleoptera, Chrysomelidae, Cryptocephalinae, Cryptocephalini), and describes four new species, namely, Cryptocephalus (Burlinius) longchiensis sp. nov., C. (Burlinius) baowenzhengi sp. nov., C. (Burlinius) tomurensis sp. nov., and C. (Burlinius) glabrelegantulus sp. nov. The species C. (Burlinius) turpis Chen, 1942, and C. (Burlinius) yangweii Chen, 1942, were revalidated and treated as distinct species. Another four species were transferred into this subgenus from the subgenus Cryptocephalus, namely, C. (Burlinius) flavolimbatus Pic, 1920 (stat. nov.), C. (Burlinius) pusus Schöller, 2009 (stat. nov.), C. (Burlinius) scutemaculatus Tan, 1992 (stat. nov.), and C. (Burlinius) shaowuanus Gressitt & Kimoto, 1961 (stat. nov.). Two species (including one more subspecies) were removed out of this subgenus, namely, C. (Burlinius) nigrolimbatus Jacoby, 1890, C. (Burlinius) pallidipes Pic, 1927, and C. (Burlinius) pallidipes nakatae Gressitt & Kimoto, 1961; they were transferred into the subgenus Cryptocephalus. Thus, the subgenus Burlinius Lopatin includes now a total of 26 species in China according to our revision. A key to all the Chinese species of this subgenus is provided as well as color illustrations and line drawings for the general habitus and genital structures.

A check-list of the Chrysomelidae (Galerucinae, Alticinae, Cryptocephalinae, Eumolpinae, Synetinae) of the Kuznetsk-Salair Mountain Area is provided. Currently, 113 species belonging to 29 genera of these subfamilies are recorded. Accurate localities are indicated for each species.

Three new species of Chrysomelidae with extraordinary extensions of the male mandibles are described: Scaphodius drehu sp. nov. and S. ferox sp. nov. (Cryptocephalinae), from New Caledonia, and Chaloenus gajah sp. nov. (Galerucinae), from Borneo. Designation of the type species of Chaloenus Westwood, 1861, is clarified. Synonymy of Scaphodius Chapuis, 1874, with Nyetra Baly, 1877, is supported. Four species of Ditropidus Erichson, 1842, described from New Caledonia, but hitherto regarded as nomina nuda, are shown to be available and are placed in Scaphodius: S. aeneus (Fauvel, 1907), comb. nov., S. nitidus (Fauvel, 1907) comb. nov., S. striolatus (Fauvel, 1907) comb. nov., S. sulcatus (Fauvel, 1907) comb. nov. Ditropidus opacicollis Fauvel, 1907, is also transferred to Scaphodius, as S. opacicollis (Fauvel) comb. nov. The genus Ditropidus does not occur onNew Caledonia. Male mandible enlargment in the Chrysomelidae is reviewed: it is common in Cryptocephalinae, but otherwise restricted to a few species of Chrysomelinae, Eumolpinae and Galerucinae. Possible reasons for its distribution in the Chrysomelidae are discussed.

This paper deals with the biological aspects of Metallactus sp. on Eucalyptus urophylla and the development of a technique to rear this insect in laboratory (25±1º C; 90±5% RH; 14-hour photophase). The following parameters were evaluated: duration, viability and number of instars of the larval stage; duration and viability of the pupal stage; case weight; longevity of male and female adults; sex ratio; sexual dimorphism; preoviposition period; oviposition period; number of eggs per female; egg period and egg viability; duration and viability of the life cycle (egg-adult period); and fertility life table.

The morphology of the larvae, pupae and adults of Camptosomata (Cryptocephalinae and sister-group Lamprosomatinae) is reviewed, with special reference to the Australian fauna. Terminology for the larval structures is redefined and a special study is made of the adult female oviposition structures. The morphological data base is studied with the phylogenetic analysis program PAUP and the variation of characters and taxa examined further with the program MACCLADE. The morphological data and the phylogenetic analyses based on these data are applied to the redefinition of the Camptosomata and constituent taxa using a cladistic methodology. The Camptosomata are redefmed and their possible sister-groups discussed. The Camptosomata are shown to be a monophyletic group and to exclude both Megascelidini (a tribe ofEumolpinae) and Synetinae. The Camptosomata comprise two subfamilies, Lamprosomatinae and Cryptocephalinae. Four tribes of Cryptocephalinae are recognised and redefined. One of these, the Cryptocephalini, with a high proportion of Australian taxa, is divided into five subtribes of 1, 3, 3, 5 and 11 genera. The following nomenclatural changes are proposed (ignoring changes of rank): Platycolaspina subtribe nov., Coenobiina subtribe nov., Ditropidina subtribe nov. and synonymy of Monachina (a homonym) and Cryptocephalina. New genera or subgenera proposed are : Semelvillea (in Platycolaspina), Ditropidella (in Ditropidina)and M elatia (in Cryptocephalina), and the subgenera Aorocarpon and Cadnwides in Cadmus Erichson (Cryptocephalina). The following generic synonymy is proposed (senior synonym first) : Leasia Jacoby(= Agetinella Jacoby); Aprionota Maulik (= Cephalocryptus Gressitt, Pycnophthalma Maulik); Ditropidus Erichson (= Bucharis Baly, Elaphodes Suffrian, Euditropidus Lea, Pleonwrphus Chapuis, Polyachus Chapuis, Prasonotus Suffrian, Tappesia Baly); Scaphodius Chapuis (=Nyetra Baly); Cryptocephalus Geoffroy(= Jaxartiolus Jacobsen andBassareus Haldeman); Aporocera Saunders(= Chariderma Baly, Chloroplisma Saunders, Cyphodera Baly, Loxopleurus Suffrian, Melinobius Jacoby, Rhombosternus Suffrian, Schizosternus Chapuis). New combinations of genera in tribes and subtribes are Mylassa Stal reinstated as a valid genus in Pachybrachini, Platycolaspis Jacoby andLeasia Jacoby in Cryptocephalini (Platycolaspina) and Arnomus Sharp and Atenesus Weise in Platycolaspina. As a result of the above new generic synonymy, several new species combinations are made. The new genus Semelvillea ,with eight species, is mono graphed. Types of three-quarters of the described species of New Zealand and Australian Cryptocephalinae were examined and the following new species synonymy is made (senior synonym first): Chlamisus aterrimus (Lea)(= C. australis Bryant); Arnomus curtipes Broun (=A. impressus Broun, =A. viridicollis Broun); Arnomus signatus · Broun ( = A. fulvus Broun, =A. vicinus Broun); Ditropidus anthracinus Erichsen ( = D. punctivarius Lea); Ditropidus aurichalceus Suffiian (=D. oblongipennis Lea); Ditropidus carbonarius Baly (=D. subsimilis Lea); Ditropidus festivus (Suffrian) (=D. suffriani Chapuis); Ditropidus maculicollis Chapuis (=D. erythroderes (Lea), =D. niger (Lea), =D. maculicollis (Weise)); Ditropidus ornatus Baly (=D. alphabeticus Lea); Ditropidus pallidipennis Chapuis (=D. dolichognathus (Lea)); Ditropidus ruficollis Saunders (=D. elegantulus Baly, =D. rufipes Saunders); Ditropidus saundersi (Baly) (=D. multimaculatus (Lea)); Ditropidus variiceps Lea (=D. marginipennis Lea); Aporocera albogularis (Chapuis) (=A. coccineus (Chapuis), =A. delicatulus (Lea)); Aporocera apicalis Saunders(= A. bicolor Saunders); Aporocera argentata (Chapuis) (= A.fasciata (Weise)); Aporocera aurantiaca (Chapuis) (=A. monticola (Blackburn)); Aporocera australis (Saunders) (=A. erosa (Saunders), =A. larinus (Lea)); Aporocera cicatricosa (Chapuis) (=A. calomeloides (Lea)); Aporocera gibba (Chapuis) (=A.lugubris (Lea)); Aporocera iridipennis (Chapuis) (=A. decens (Weise)); Aporocera libertina (Suffrian) (=A. castor (Lea)); Aporocera nigrolineata (Chapuis) (=A. castigatus (Lea)); Aporocera parenthetica (Suffrian) (=A. melanopa (Lea)); Aporocera paupercula (Germar) (=A. rufescens (Boheman)); Aporocera ring ens (Chapuis) (=A. clypealis (Lea)); Aporocera tasmanica (Saunders) (=A. impressicollis (Boheman)); Aporocera viridipennis (Saunders)(= A. t-nigrum (Lea));Aporocera viridis (Saunders)(= A. aereus (Suffrian)); Aporocera analis (Chapuis) (= A.foveiventris (Lea)); Cadmus crucicollis (Boisduval) (=C. canaliculatus Chapuis, = C. rugosus Suffrian); Cadmus litigiosus Boheman (=C. vibrans Suffrian); Cadmus cariosus Chapuis (=C. minor (Blackburn)); Cadmus pauxillus Chapuis (=C. perlatus Lea); Cadmus braccatus (Klug) (=C. saundersi Baly); Cadmus breweri(Baly)(= C. duboulai Baly). Representation of Cryptocephalinae in Australia is shown to be as follows (number of genera in brackets) : Chlamisini (1), Clytrini (1), Pachybrachini (1, introduced), Platycolaspina (4), Coenobiina (1), Ditropidina (2) and Cryptocephalina (4). Larvae and adults of the genera and subgenera in Australia and the south-western Pacific are diagnosed and keys are provided for the identification of these taxa at both life stages. The entire Camptosomatan fauna of Australia and the south-western Pacific is catalogued.

În rezultatul cercetărilor efectuate şi a datelor din literatură au fost identificate 57 specii de crizomelide. În total în Rezervația Plaiul Fagului au fost identificate în premieră 33 specii (cu excepţia subfamiliei Alticinae), ce aparţin la 15 genuri (Cassida, Chrysolina, Chrysomela, Clytra, Cryptocephalus, Galeruca, Gastrophysa, Hispa, Lochmaea, Luperus, Pachybrachis, Phratora, Phyllobrotica, Plagiodera, Plateumaris) din 5 subfamilii (Cassidinae, Chrysomelinae, Cryptocephalinae, Donaciinae, Galerucinae). Pentru aceste 33 specii este prezentată o scurtă caracteristică cu referire la aria de distribuție a speciei, microhabitat și trofică. Cea mai mare parte a speciilor menționate ca noi au distribuție euro-siberiană și transpalearctică (cu câte 8 specii fiecare), urmate de cele cu distribuție europeană (7 specii) și european-asiatică (6 specii). În fauna Rezervației Plaiul Fagului au fost identificate doar 2 specii cu distribuție palearctică și câte o specie europeană și central asiatică și est-mediteranean. Preferințele speciilor față de umiditate diferă și ele, 16 fiind xerofile, 10 higrofile și 7 mezofile. Cele mai multe specii au fost colectate în lizieră și poiene, urmate de luncă și malul iazului. Este remarcat faptul că inventarierea faunei crizomelidelor din Rezervația Plaiul Fagului nu este finalizată și numărul de specii poate fi mai mare. Aceasta determină studiile ulterioare privind fauna familiei Chrysomelidae din această rezervație.
