Abstract The atyid shrimps of Caridina nilotica species group from China are reviewed. Taxonomic diagnosis and discussions are given to three species so far known from China, viz. Caridina gracilipes De Man, 1892, Caridina macrophora Kemp, 1918 and Caridina elongapoda Liang & Yan, 1977. Detailed morphological description and illustrations are provided for a new species. Caridina sheni sp. nov. is morphologically similar to C. gracilipes but could be distinguished by its much longer dactylus of third and fifth pereiopods, and lower number of ventral rostral teeth.

The present study, based on a faunistic and ecological survey of caridean shrimps from Dong’ao Island, Guangdong Province, expands the knowledge of morphology, colouration, and distribution of three species, two of which belong to genus Caridina and one belong to genus Marcrobrachium. Caridina zhujiangensis, new species is distinguished from the closely related species C. typus H. Miline Edwars,1837 by shorter rostrum and with only one ventral margin teeth, the shape of the endopod of the first male pleopod and the appendix interna arising from distal 1/3 of endopod. Macrobrachium dongaoensis, new species, can be distinguished from its congeners M. inflatum Liang & Yan, 1985 by a combination of characters which includes short rostrum, the subequal male second pereiopods, the non–inflated palm, and the longer merus. A diagnosis of three speciesmore and full description of two new species are presented.

Caridina typus var. brevirostris Roux is shown to be specifically different from Caridina typus H. Milne Edwards, 1837. A new name Caridina jeani is thus proposed for the species as the name Caridina brevirostris is preoccupied by C. brevirostris Stimpson, 1860. The species is re-described and illustrated in detail based on syntypic specimens. It differs markedly from Caridina typus by possessing sexual dimorphism on the third and fourth pereiopods. A lectotype is designated.

The mainland of Sulawesi is well known for its high diversity of freshwater shrimps. However, many small islands surrounding Sulawesi have been neglected and have not been unexplored. Here, we report on the freshwater shrimps of the Banggai Archipelago, eastern Sulawesi, based on field collections between 2017 and 2019 on four islands, Peleng, Labobo, Bangkurung, and Banggai. Eleven species were found: Caridina brevidactyla J. Roux, 1920, Caridina brevicarpalis De Man, 1892, Caridina gracilipes De Man, 1892, Caridina gracilirostris De Man, 1892, Caridina serratirostris De Man, 1892, Caridina typus H. Milne Edwards, 1837, Caridina weberi De Man, 1892, Macrobrachium australe (Guérin-Méneville, 1838), Macrobrachium equidens (Dana, 1852), Macrobrachium lar (Fabricius, 1798), and Macrobrachium latidactylus (Thallwitz, 1891). One species, C. brevidactyla, is a newly recorded from Sulawesi. Knowledge of the diversity of the freshwater shrimp fauna can contribute to the conservation of species and their habitats.

The biogeographic and phylogenetic relationships of six of the eight Australian genera of freshwater shrimp from the family Atyidae were investigated using mitochondrial 16S rDNA and cytochrome oxidase I sequences. Previous studies on two of the epigean genera (Caridina, Paratya) indicate that Australian species have strong links to congenerics from outside, with Australian members of Paratya being monophyletic and Caridina polyphyletic. The present study found that the endemic Australian epigean genus Australatya forms a strong clade with Pacific ‘Atya-like’ genera (Atyoida, Atyopsis), and that the endemic Australian epigean genus Caridinides falls within a clade containing Caridina species from the Australian ‘indistincta’ group. The two hypogean genera included in this study (Parisia, Pycnisia) form a strong clade in all analyses, implying an Australian subterranean speciation. The possibility of a relationship between Parisia/Pycnisia and an Australian Caridina species may have implications for the monophyly of the highly disjunct genus Parisia (Australia, Madagascar, Philippines). Parisia may descend from local Caridina species and represent convergent morphologies.

Since the study of Richard and Clark (2009), additional material of Caridina africana Kingsley, 1882 has been examined and as a consequence C. nilotica var. paucipara Weber, 1897 is considered to be a junior synonym of C. africana. Material of Caridina serratirostris De Man, 1892, C. angulata Bouvier, 1905, C. brachydactyla De Man, 1908 and C. moeri Woltereck, 1984 is reported, and redescribed. Caridina serratirostris and C. angulata are reported for the first time from the African mainland, both species being previously known from Madagascar. The first record of C. brachydactyla from the African continent is also noted. Furthermore, Caridina nilotica var. natalensis De Man, 1908 and Caridina nilotica var. brevidactyla J. Roux, 1920 are considered to be junior synonyms of C. brachydactyla. Part of the type series of C. brachydactyla was examined for the present study and this material together with the description and figures of the rostrum illustrated by De Man (1892) as Caridina wyckii appear to be three different species: C. brachydactyla s. str. and probably two new species. These are not described due to lack of additional material available for study. However, two new African species are described and an identification key is provided.

Caridina biyiga sp. nov. is described from Leichhardt Springs, Kakadu National Park, Northern Territory, Australia, based on morphological and molecular data. The new species is highly distinctive among its congeners in having the dactylus of pereiopod 5 similar to the dactyli of pereiopods 3–4 and lacking the comb-like row of spiniform setae typical of the genus. The branchial formula is also distinctive for the genus in lacking an arthrobranch at the base of pereiopod 1 and in having a vestigial epipod on maxilliped 1. Despite the distinctive morphology of the new species, the molecular data did not provide strong support for the recognition of a new genus. Phylogenetic analyses of Australian Caridina using the mitochondrial 16S rDNA gene fragment placed the new species in a well-supported clade containing at least one typical species of Caridina. Within this clade, referred to as the ‘thermophila’ group, Kimura 2-parameter (K2P) genetic distances of 16S rDNA between the new species and sister taxa ranged from 5.1–6.0%. Analyses using the mitochondrial 3’ COI gene fragment from species of the ‘thermophila’ group yielded K2P genetic distances between the new species and its sister taxa ranging from 10.4–15.1%. A preliminary illustrated key to Northern Territory Caridina is provided. The conservation significance of Leichhardt Springs and its aquatic fauna are also briefly discussed.

Caridina ravisankarani sp. nov. is a cave-adapted species, collected during June and November 2018 and January 2019 from a limestone cave (CN2) on Interview Island, Andaman and Nicobar Islands. The shrimps were collected from a stream, sourced through the percolation of rainwater, which reduces during the post-monsoon months. The species is closely related to Caridina typus H. Milne Edwards, 1837, Caridina villadolidi Blanco, 1939 and Caridina jeani Cai, 2010. A detailed comparison of characters and a key for identification are given in the text. The present species can be diagnosed by the presence of: short rostum with edentulous upper margin and ventral margin with 2 minute teeth situated at the distal part; outer antennular flagellum with 16 segments at the basal part swollen; highly atrophied propodus and dactylus of endopod of 2nd maxilliped; bushy long setae on fingers of 2nd chelate legs; dactylus of 5th pereopod with 42–43 comb-like bristles; dieresis with 18 spines; dorsal surface of telson with 4–5 pairs of spines and disto-median region doesn’t end in a point, outer lateral pair of spines absent and eyes with cornea pigmentation variable, from totally absent to a small black spot. Fecundity is 1300 eggs with an average length 0.71±0.03 mm and width 0.42±0.03 mm (Mean±SD).

Abstract In this study, four species of atyid shrimps of the genus Caridina, viz., Caridina cantonensis Yü, 1938, C. breviata N. K. Ng & Cai, 2000, C. gracilipes De Man, 1892 and C. macauensis sp. nov., are documented from Macau, China for the first time. The new species, C. macauensis sp. nov., is identified using morphological and molecular data. According to its morphology, C. macauensis is distinguished from the closely related species C. trifasciata Yam & Cai, 2003, by a shorter rostrum, male second pereiopod and colouration. A diagnosis of the three known species and a full description of C. macauensis sp. nov. are presented. Furthermore, genetic data of C. macauensis sp. nov. derived from the mitochondrial cytochrome c oxidase subunit I (COI) support that this species has a sufficient interspecific divergence from its congeners.

Caridina stellatasp. nov. is described from streams in Guangxi, south-western China. The new species clearly belongs to “Caridina serrata group” of the genus and shows a morphological similarity with C. cantonensis Yu, 1938, C. serrata Stimpson, 1860 and C. pacboDo et al. 2020. Caridina stellata is distinguished from congeners, based on differences in its male first pleopod and appendix masculina morphology, along with COI and 16S rRNA molecular evidence. The first pleopod endopod in male is rectangle, about 0.70 × length of exopod, about 3.7–3.9 × as long as proximally wide, inner margin concave, bearing nearly equal spine setae, outer margin bearing nearly equal long and dense spine setae; appendix interna well developed, arising from distal 1/5 of endopod, reaching to end of endopod, with cincinuli distally. The new species displays a unique and brightly coloured pattern and, therefore, can be easily recognised in the field. Liang & Zhou, 1993 described C. cavernicola from the Lenggu Cave, Du’an County, Guangxi. However, the description was based exclusively on two females. We have collected specimens of both sexes near the type locality and describe herein the previously unknown male and present morphological data on females. Data on the habitat, ecology and levels of threat of the two species are provided and suggest that they should be categorised as vulnerable (VU) under the current IUCN Criteria.

The taxonomy of the freshwater shrimps Caridina (Atyidae) is very complex and confused mostly because the morphological characters that have traditionally been used for species delimitation and identification are highly plastic. There is thus a need for an integrative approach to their taxonomy. In total, 42 specimens belonging to either Caridina buehleri Roux, 1934 or Caridina gueryi Marquet, Keith & Kalfatak, 2009 were examined. We combined here morphological data from 12 specimens from the whole distributional range of the species, including type specimens with 16S mtDNA analyses from seven freshly sampled specimens, to verify the specific status of Caridina buehleri from Papua New-Guinea, Central Sulawesi, Western Samoa and the Solomon Islands, and C. gueryi from Vanuatu. The comparison of 24 morphological characters showed that morphological variations of character traits between C. gueryi and C. buehleri are widely overlapping and that no morphological feature can effectively split specimens into two clear groups. Molecular characters corroborated these results, as specimens from both groups were only separated by a 2% p-distance, a genetic distance that is coherent with their potentially high dispersal abilities. We thus consider C. gueryi as a junior synonym of C. buehleri. Finally, C. buehleri is characterised mainly by a styliform and characteristically indented rostrum and a long stylocerite. Detailed re-descriptions of the type specimens of C. buehleri and C. gueryi are given, as well as their geographical and ecological distribution.

Caridina longirostris H. Milne Edwards, 1837 described from specimens supposedly from La Macta River near Oran, Algeria, is an emblematic species of the ‘C. nilotica complex’. Until now this species was thought to have a wide distribution in the Indo-Pacific region. Recently, numerous specimens identified as C. longirostris were collected from various Indo-West Pacific localities. In the context of integrative taxonomy, both old and newly collected specimens were morphologically and genetically studied. Four species allied to C. longirostris are here identified: C. appendiculata Jalihal & Shenoy, 1998, C. brevidactyla Roux, 1920, C. gracilipes De Man, 1892 and C. meridionalis Roux, 1926. Detailed re-descriptions of these four species are given as well as their geographical and ecological distributions. Caridina nilotica var. brevidactyla is revalidated as the species C. brevidactyla, and C. coulaborensis Richard & Clark, 2014, C. fritzi Richard & Clark, 2014 and C. solamulieres Richard & Clark, 2014 are considered junior synonyms of C. meridionalis. The position of these species in the troublesome ‘C. nilotica complex’ is clarified and some species are synonymised. A key is provided to facilitate identification.

A faunistic and ecological survey was conducted to document the diversity of freshwater atyid shrimps of Dawanshan Island. Two species of Caridina that occur on this island were documented and discussed. One of these, Caridina tetrazonasp. nov. is described and illustrated as new to science. It can be easily distinguished from its congeners based on a combination of characters, which includes a short rostrum, the shape of the endopod of the male first pleopod, the segmental ratios of antennular peduncle and third maxilliped, the slender scaphocerite, and the absence of a median projection on the posterior margin. Live individuals of the new species display a unique coloration pattern with four dark blue transverse bands on the body, and can be easily recognized in the field. So far, despite considerable surveying efforts made on neighboring islands, this species has only been found from a small stream on Dawanshan Island, which suggests that it may have a very limited range, probably endemic to Dawanshan Island. Molecular characteristics of the mitochondrial cytochrome c oxidase subunit I (COI) demonstrate that this species shows sufficient interspecific divergence from its congeners, including C. serrata Stimpson, 1860, which was found in four streams on Dawanshan Island, and has been previously reported on the neighboring islands of Hong Kong, Dong’ao, Wailingding, and Guishan.

The atyid shrimp Caridina linduensis Roux, 1904, has not been reported since its description more than a century ago. We here redescribe and figure this poorly known species based on new material from its type locality, Lake Lindu, Central Sulawesi, Indonesia. Two new species, C. dali sp. nov. and C. kaili sp. nov. are also found in this lake and they are described and illustrated. Compared to C. linduensis, C. dali sp. nov. is distinguished by its relatively shorter rostrum which only overreaches the end of basal segment of antennular peduncle and the fewer teeth on the incisor process of the mandible. Caridina kaili sp. nov. can be separated from C. linduensis by its extremely short rostrum, which reaches almost or just reaches the end of the basal segment of the antennular peduncle, proportionately stouter second pereiopod and larger egg size. The two new species also prefer different habitats; C. linduensis is a true lake inhabitant, C. dali sp. nov. can be found both in the lake itself and associated streams while C. kaili sp. nov. is an obligate stream species.

This study investigated the importance of dispersal and retention processes during early ontogeny for three caridean shrimp species that complete their entire life history in freshwater. Directional traps were used to examine the small-scale movement patterns of shrimp into and out of nursery habitat patches (slackwaters) in a small lowland river in southeastern Australia. Movement patterns provided evidence for two contrasting life history based dispersal and retention strategies. For the two smaller atyid species, Paratya australiensis and Caridina mccullochi , the majority of larvae remained within the slackwater in which they were hatched until the final stage of development, at which point dispersal, either among slackwaters or out of slackwaters to faster-flowing pool and run habitats, occurred. For the larger palaemonid species, Macrobrachium australiense , larvae were hatched into slackwaters and dispersal occurred predominately during the first stage of larval development and then decreased as development progressed. Despite the differences in dispersal strategies among species, movement was mostly associated with a particular larval stage and thus emphasizes the importance of retention during critical developmental periods and of the potential impact that flow alteration could have on these and other species with similar life histories.

Lake Poso, an ancient lake system on the Indonesian island Sulawesi, harbours an endemic species flock of six, four lacustrine and two riverine species of the freshwater shrimp genus Caridina. In this study, five new lacustrine species are described, bringing the total to eleven species altogether. The number of lacustrine species is more than doubled to nine species compared to the last taxonomic revision in 2009. One of them, Caridina mayamareenae Klotz, Wowor & von Rintelen, sp. nov., even represents the first case of an atyid shrimp associated with freshwater snails which is morphologically adapted to living in shells. An integrative approach was used by providing a combination of morphological, ecological, and molecular data. Based on standard morphological characters, distribution, substrate preferences, and colouration of living specimens in the field, five distinct undescribed species could be distinguished. To support our species-hypothesis based on the mitochondrial genes 16S and COI, a molecular phylogeny was used for all eleven species from Lake Poso. All species form a well-supported monophyletic group, but only four morphospecies consistently correspond to mtDNA clades – a possible reason could be introgressive hybridisation, incomplete lineage sorting, or not yet fixed species boundaries. These results are discussed further in the context of adaptive radiation, which turned out to be more diverse than previously described. Finally, yet importantly, subjecting all new species to similar threats and to the same IUCN category and criterion than the previously described species from the lake is recommended.

The present study used Scanning Electron Microscopy (SEM) to examine the functional morphology of the feeding and associated appendages of the detritivore-collector atyid shrimps Caridina cantonensis Yu, 1938 and C. trifasciata Yam & Cai, 2003. The third maxillipedes of both species are equipped with serrate setae ending in a terminal pore, which setae may thus serve both as mechano- and chemo-receptors. Pereiopods 1 and 2 have dense, long, simple setae and single-rowed serrate setae for effective brushing fine-particulate organic matter and scraping periphyton from the substratum. Pereiopods 3 and 4 are heavily armed with large cuspidate setae and with simple type setae, which can be used for food collection or providing strong anchorage. The dactylus of pereiopod 5 is oval, flattened, and equipped with serrate setae on the ventral margin. In contrast to the suspension-feeding Atya innocuous (Herbst, 1792), Caridina spp. show a lower setal diversity, while all setal types on the pereiopods are mechano-receptors, being specialized for collecting food.

AbstractThe aesthetascs of the prawns are chemo- and mechano-receptors which exhibit diversity in number and shape depending on habitat and environment. In marine forms (both adults and larvae) they arc more numerous, longer, slender and uniformely thin wallcd. In adults of freshwater prawns they are fewer, shorter, divided into a thick walled stalk and a thin distal cob-like portion. However, they arc structurally different and positioned differently in the atyid genus Caridina and palaemonid genus Macrobrachium. Further, Caridina exhibits sexual dimorphism with males possessing a greater number of aesthctascs-bearing segments than females, unlike Macrobrachium which does not show such dimorphism. As far as larvae are concerned, in the 'inland species' of both genera, which complete their metamorphosis purely in freshwater, the 'freshwater- type aesthetases' appear in the first and second zoeal stages in totally or partially abbreviated type of development respectively. On the other hand, the early zoeal stages of 'coastal species' possess 'marine-type aesthetascs' indicating salinity dependence for their successful metamorphosis. These aesthetascs get shortened in late larval stages and subsequently get transformed into typically 'freshwater type' from postlarva onwards. A unique kind of 'branched larval aesthetascs' has been observed in two species of Macrobrachium. Thus, despite their common sensory function, the aesthetascs exhibit structural variations depending on environment and also play an important role as salinity indicators in the culture of freshwater prawns.

Glyphosate-based herbicides used to control weeds and invading alien plant species in South Africa ultimately end up in freshwater ecosystems, but no South African environmental water quality guideline exists to regulate these bio-active chemicals. Ecotoxicological tests to assess the possibility of using lipid peroxidation (LPx) in Caridina nilotica as a potential biomarker of Roundup®, a glyphosate-based herbicide, pollution were conducted. In two separate tests, 40 days post hatch shrimps were exposed to different concentrations of 4.3, 6.7, 10.5, 16.4, 25.6 and 40.0 mg/L in a 96 h acute toxicity test; and 2.2, 2.8, 3.4, 4.3 and 5.4 mg/L in a 21 d chronic toxicity test, using static-non renewal and static-renewal methods, respectively. Shrimp whole body LPx was estimated by thiobarbituric acid reactive species (TBARS) assay, performed by a malondialdehyde (MDA) reaction with 2-thiobarbituric acid (TBA) measured spectrophotometrically. Final MDA concentrations were expressed as nmol MDA produced/mg protein. Results showed that LPx was significantly lower in control animals than in animals exposed to different Roundup® concentrations, (p < 0.05). The present work provides an ecotoxicological basis for the possible use of LPx in Caridina nilotica as a biomarker for monitoring Roundup® pollution in freshwater ecosystems.

The Caridina indistincta complex is a group of closely related atyid shrimps that inhabit coastal freshwater streams throughout north-eastern Australia. Using mitochondrial DNA sequence data (cytochrome oxidase 1, CO1), we (1) inferred the timing of speciation in the C. indistincta group and (2) examined the intraspecific phylogeographic patterns within the group. Assuming a shrimp-specific rate of CO1 evolution, the level of sequence divergence among species suggests that speciation took place during the Miocene epoch. Within one widespread mainland species, phylogeographic patterns suggest strong geographic 'regionalisation' of mtDNA lineages that are most likely of Pleistocene origin. By contrast, another species comprises two highly divergent mtDNA lineages that occur in sympatry. We suggest that although Pleistocene sea-level regressions appear important in generating population-level phylogeographic patterns, these events were largely unimportant in the formation of species in this group.

Shrimp–sponge associations occur frequently in marine ecosystems, serving as model systems for the evolution of eusociality. Here, we describe the first known instance of such association in freshwater from an ancient lake in Indonesia. The shrimp Caridina spongicola forms an exclusive and probably commensal association with a yet undescribed spongillinid sponge. Phylogenetic and ecological data suggest a comparatively recent origin of both taxa. Climatic fluctuations may have facilitated speciation and occasional hybridization of the shrimp species, which is derived from a rock-dwelling ancestor. Their extremely localized occurrence in an increasingly disturbed area makes both taxa a conservation priority.

Caridina sp. is an atyid shrimp occupying coastal streams in south-eastern Queensland and northern New South Wales. Shrimps from two geographic regions in south-eastern Queensland were examined. An analysis of 7 allozyme loci showed very high levels of genetic differentiation among catchments (F ST = 0.65) with much lower levels within catchments. This indicates extremely limited dispersal among catchments with greater levels within catchments. The levels of genetic differentiation were even greater than previously reported for two other atyid shrimp species occurring in upland rainforest streams. Populations from the Noosa River were more similar to those from the Glasshouse Mountains than to those from the geographically closer Tin Can Bay streams. This pattern was remarkably similar to that of a fish species occurring in the same streams and may reflect a recent confluence of streams from the Glasshouse Mountains and the Noosa River regions.
