About the lab

Our lab focuses on A) studying the systematics and diversity of certain freshwater invertebrate groups from India specifically focusing on Rotifera, Branchiopoda and Ostracoda, B) Diversity dynamics of freshwater invertebrates in response to anthropogenic disturbances and C) Community ecology of invertebrates in freshwater pools.

We present the first record of the freshwater gastropod Pettancylus tenuis from the Pune region of India. This species, which resembles a limpet, was found in November and December 2020 in a wetland formed near the confluence of Mula and Ram rivers in Pune city. The shell characters of the specimens match the available description of the species. The other records of this species from Maharashtra are nearly 150 km from Pune.
David Frey raised the hypothesis of non-cosmopolitanism in Cladocera in a series of his publications (Frey 1982, 1987). Since then, researchers have taken the effort to revise species groups with wide geographic distribution around the world (e.g. Kotov & Dumont 2000; Sinev 2015; Van Damme & Dumont 2008a; Sinev & Elmoor-Loureiro 2009). The polyphyletic nature of the genus Alona Baird, 1843 (Van Damme et al. 2010) has further substantiated the view that cladocerans are non-cosmopolitan, with the creation of many new genera to accommodate the several species groups known within this genus (Van Damme & Dumont 2008b; Sinev & Kobayashi 2012; Van Damme & Dumont 2009; Alonso & Sinev 2019).
I present taxonomical re-descriptions of two Indian spinicaudatan species deposited at the Smithsonian National Museum of Natural History, USA, emphasizing on a few characters not highlighted in the original descriptions. Specimens collected from South India and deposited in the museum forty years ago were assessed and re-described. The study shows that the Cyzicidae species deposited as Caenestheriella sp. is Ozestheria indica while the Eulimnadia species is the widely distributed Eulimnadia michaeli. Many of the taxonomical characters were variable and did not exactly match the earlier description for both the species. Ozestheria indica could be distinguished from other valid Indian species on the telson characters and its occurrence proximity to the type locality of the species. This species is currently restricted to Peninsular India. Eulimnadia michaeli could be identified based on its characteristic egg surface morphology, though, the inner layers of the egg did vary when compared with the western Indian population. Using museum material, the validated species tally of Indian spiny clam shrimps now stands at 8 while 15 still await re-examination.
