On a small collection of amphipods (Crustacea, Amphipoda) from Chilika Lake with the description of three new species and a new genus.

The current study was conducted on the basis of a small collection of amphipods made from Chilika Lake that contained 4 species. Three were described as new species, including one new genus: Parhyale kalinga sp. nov., Chilikorchesta chiltoni gen. nov. sp. nov. and Grandidierella rabindranathi sp. nov., while a fourth one was a previously reported species: Quadrivisio bengalensis Stebbing, 1907. Parhyale kalinga sp. nov. can be differentiated from its closely related congeners Parhyale basrensis Salman, 1986 and Parhyale darvishi Momtazi & Maghsoudlou, 2016 by having male gnathopod 2 propoduswith 2 robust setae at the base of the palm and 2 small setae slightly behind the palm and dactylus much smaller than palm. Chilikorchestia chiltoni gen. nov. sp. nov. can be differentiated from the closely related genus Morinoia Lowry & Myers, 2019 by its incrassate male antenna 2 and untapered telson. Grandidierella rabindranathi sp. nov. can be differentiated from its closely related congeners G. mahafalensis Coutière, 1904 and Grandidierella nioensis Myers, Sreepada & Sanaye, 2019 by having male gnathopod 2 carpus oval shaped with both margins convex.
