Despite being one of the dominant groups in freshwater ecosystems, morphological and ontogenetic studies on aquatic Hemiptera have received little attention in the Oriental region. We present the ontogenetic trajectory and allometry of the widespread Oriental belostomatid species, Diplonychus rusticus (Fabricius) for the first time. We have measured nine different morphological variables throughout the growth of the bug using both field captured and laboratory reared specimens. Our results suggest that the developmental instars can be distinguished by the size variables, as seen in the Principal Component Analysis. On the basis of a CHAID (Chi-squared Automatic Interaction Detection) based regression tree, we also show that the characters - total length without head and maximum width - prove to be adequate for effective instar identification. The multivariate allometric growth pattern shows that different body parts exhibit different types of allometry. This is apparent in the allometry exhibited by forelegs and mid and hind legs, which show allometry of opposite polarities. This may be due to the different functions attributed to these body parts. Our results show that the growth pattern in D. rusticus is comparable with the New World genus Belostoma, suggesting a conserved growth pattern in the family Belostomatidae. © 2017 Elsevier Ltd.

The Indian subcontinent has a specific biogeographical history, but has remained understudied with respect to invertebrates like the Anostraca. In this study, we discuss the anostracan diversity and zoogeography on the subcontinent. We collected all pertinent literature and considered nineteen bioclimatic variables along with altitude and its terrestrial ecoregions. The study area was overlaid with 10,000 km2 grids, and five hundred random GIS data points per grid were extracted for analysis besides the species locality data. Species richness estimators predict at least 3–4 more species to the existing list of 19 species. The beta diversity measure βsim reveals two zoogeographic “zones,” viz., a Northern (NZ) zone and the rest of the subcontinent (RS) comprising the Central (CZ) and South (SZ) zones by Unweighted Pair-Group Method using arithmetic averages clustering and Analysis of Similarity. Complementarity index shows that no fauna is shared between NZ and RS, while CZ and SZ share 50% of the species. Principal Component analysis shows that NZ and RS differ somewhat from one another climatically. NZ and RS have different ecoregions with montane and temperate grasslands commonly observed in NZ while the latter comprising tropical forests, implying differences in soil geochemistry which is crucial for anostracan distribution. © 2017 Springer International Publishing Switzerland

We assessed the species richness of Cladocera of the Western Ghats and surrounding areas of Maharashtra and Goa. Data of 230 samples from about 80 localities collected between 2009 and 2013 revealed 51 species in six families. Non-parametric estimators of species richness, Chao 2 and Jackknife 2, estimated the real total at 58 and 63 species, suggesting a coverage of 80% of the total species of the area. This fauna was compared with that of other countries from the Oriental region and found to be relatively species-poor, which is not in line with the biodiversity rich area status of the Western Ghats. Reasons for this are unclear. Complementarity among the cladoceran faunas of different countries belonging to the Oriental region increased with latitude and altitude. Along with the complementarity index, a comparison of family and generic occurrences of Cladocera revealed that family-level representation was similar between countries but species occurrences (like Daphnia species) varied. The subgenus Daphnia was reported only from Nepal while Ctenodaphnia was common in all countries of the Indian region. Biogeographically, the fauna was mainly composed of wide-ranging tropical species, mixed with some rare Palaearctic elements. Only two species were endemic to India. Of another one, the closest relative lives in Yucatan, Mexico, and thus has a tropical Amphi-Pacific distribution. © 2015 Cladocera of the northern Western Ghats, India Allrights received.

We describe and figure Moina hemanti sp. nov. from ephemeral pools on the campus of Pune University, India. Although the pools flood during the monsoon, the moinid only appears irregularly and for a short period of time. In morphology, it is extremely close to Moina dumonti from Mexico and Cuba. This geographic gap remains unexplained for the time being, although more similar cases among cladocerans are on record. Molecular analysis has suggested that M. hemanti is relatively close to Moinodaphnia, and might form a genus in its own right, presumably together with M. dumonti. The latter, however, remains to be analyzed. Further candidates for this clade are Moina oryzae and M. rostrata, if the presence of an ocellus and/or a rostrum can be shown to be apomorphies.

The genus Haploclastus is represented by eight species in India. In this paper, we synonymise Haploclastus robustus Pocock, 1900 with H. validus Pocock, 1899. H. himalayensis Tikader, 1977 is transferred to the genus Chilobrachys based on a generic character, the presence of enlarged paddle setae on prolateral side of maxillae. We provide additional information on morphometry and photographs of the palp and stridulatory setae that are lacking in the original description.

Members of the chydorid genus Kurzia Dybowski & Grochowski, 1894 (Branchiopoda: Anomopoda) are typically known from the Holarctic and the Neotropics (Rajapaska & Fernando 1986; Hudec 2000; Elmoor-Loureiro 2002; Kotov, 2004). One representative of the sub genus Kurzia, Kurzia (Kurzia) latissima (Kurz 1875) has been reported from India, in the Oriental Zone. These reports either have unreliable or no illustrations (Rane, 1983; Michael & Sharma 1988; Padhye & Dumont 2015). Recently, Chatterjee et al. (2013) have stated that records of K. latissima from India appear morphologically similar to K. latissima s.str. but have not elaborated on it. The aim of this correspondence is to present an initial diagnosis and provide illustrations of a Kurzia latissima-like population from the Northern Western Ghats, Maharashtra Province, India, along with comments on its distribution.

An updated inventory of large branchiopods of the Western Maharashtra state, India is presented for the first time. Employing current identification keys, we have detailed the egg morphology of Eulimnadia indocylindrova, which shares some similarities with E. geayi from South America and E. alluaudi from Madagascar, based on these egg characters. A thorough re-description of few morphological traits of the same species is also presented. We also have described the female of a Cyzicus species seen rarely from the studied region. Distributional comments on few species are also reported. Copyright © 2015 Magnolia Press.

The large branchiopod crustaceans (fairy shrimp, tadpole shrimp, and clam shrimp) of India have been examined with varying degrees of scientific rigour since the late 1800s. Although 86 nominal species have been reported for India, the validity of many is in question - particularly for the clam shrimp. Most Indian endemic taxa are poorly described; some lack type material or the type material has been lost. Most recent revisions of key groups have made no attempt to validate identifications using existing type material, or even to procure topotype material.Worse, recent reviews treat old synonyms as valid names without any analysis or explanation.We provide a review of the taxa from the Indian subcontinent (Bangladesh, India, Nepal, Pakistan, and Sri Lanka) taking a strongly conservative approach to assessing the reported species.We recognize only 42 species: 16 anostracans, 2 notostracans, 3 laevicaudatans, 21 spinicaudatans (with reservations), and a single species of cyclestherid. This should establish a base point for future work on the branchiopods of the subcontinent. © 2015. Published by Brill NV, Leiden.

Species diversity and distribution of Cladocera in the freshwater rock pools of the northern Western Ghats have been reported. Fifty-nine samples collected from 12 different localities contained 22 species belonging to five families. Chydoridae was the most species rich family with 12 species followed by Daphniidae with five species. Species of the genus Alona were relatively rare, but two other alonines, Leydigia (N.) ciliata and Karualona cf. karua were commonly observed. Congeneric species never co-occurred in the same pool. Distributional maps and taxonomic comments are presented for the commonly observed species. Jaccard's similarity index (CJ) comparing localities showed overall similarity. © EDP Sciences, 2015.
