A new species of Leptestheria (Crustacea: Branchiopoda: Spinicaudata) from Western Maharashtra, India

Sameer M. Padhye

Hemant V. Ghate²

Abstract: We describe a new species of Leptestheria from a rock pool in the Western Ghats of Maharashtra, India. This species is distinguished from all other Indian congeners by its distinct telson characters and occipital condyle. We also present a comparative table of useful morphological characters of all described Indian Leptestheria species.

Large branchiopod crustaceans are flagship species of temporary water bodies, especially in arid and semi-arid regions. Less information is available about the large branchiopods of tropical Asia compared to other parts of the world such as the Americas. To reduce this disparity, we surveyed large branchiopods from the semi-arid region of Maharashtra state, India. Sampling at 29 sites over four years revealed nine species representing four orders. This is the highest diversity ever reported from a single regional study in India. Anostracans were the most commonly occurring group, whereas the spinicaudatans Leptestheria cf. nobilisSars, 1900, L. jaisalmerensisTiwari, 1962, and Eulimnadia michaeliNayar & Nair, 1968 were very rare. Leptestheria jaisalmerensis had been known previously only from its type locality nearly 1,200 km north of our study region. Congeneric assemblages of the anostracans Streptocephalus dichotomusBaird, 1860 + S. simplexGurney, 1906 and the spinicaudatans Leptestheria cf. nobilis + L. jaisalmerensis were collected. Temporary aquatic habitats are threatened due to adverse anthropogenic activities, especially in developing countries like India. The endemic species of large branchiopods in the Indian subcontinent should be red-listed, as is done elsewhere.

Spinicaudatan clam shrimps are an evolutionarily ancient lineage restricted to temporary freshwater pools. Use of classical morpho-taxonomic approaches alone have led to some issues in the taxonomy of this group, which are now being resolved through integrative taxonomy. Here, we describe two new leptestherid spiny clam shrimps Leptestheria chalukyae sp. nov. and Leptestheria gomantaki sp. nov. from peninsular India based on their unique morphological characters and distinct phylogenetic position. We also re-describe Leptestheria nobilis and present an overview of the morphological characters of all the Indian leptestherids. Most of the conventional taxonomic characters appear to overlap among all the Indian species, although the combination of occipital condyle shape and the cercopod marginal spines arrangement in combination, appear to be useful in separating leptestherid species.

We assign the only Australian leptestherid clam shrimp, Eoleptestheria ticinensis (Balsamo-Crivelli, 1859) to a new species status, Leptestheria timmsi sp. nov., based on the latest molecular phylogeny of spinicaudatan clam shrimps from a previous study. We provide a redescription of the species, highlighting morphological details not explored previously for this species. We also present a comparative account of all Eoleptestheria species and populations throughout the world. The head morphology of Leptestheria timmsi sp. nov. overlaps with other populations of Eoleptestheria and a few Leptestheria species. The telsonic and cercopod marginal spines seem to increase in size posteriorly in L. timmsi sp. nov., unlike in many other Eoleptestheria populations.
