WEST BENGAL : Achipur in South 24 Parganas District — Sharma (1980) ; MEGHALAYA : Sharma & Sharma (1990) ; GENERAL RECORD : Naidu & Rao (2004) . Habitat (as in Indian records): Freshwater; among filamentous algae and aquatic plants. Distribution. USA and India . Remarks. Naidu & Rao (2004) , following Schwank’s (1990) classification indicate several species as belonging to the subgenus Euichthydium . However, as explained by Kånneby et al . (2009) , the subgenus Euichthydium Schwank, 1990 is invalid because it contains the type-species of the genus Ichthydium , therefore it must bear the same name as the genus. Ichthydium auritum was found in India twice and both records are from West Bengal ( Sharma 1980 ; Sharma & Sharma 1990 ). The specimens found match the original description especially in showing the posterior lobes of the head in the form of ear-like flaps. Regarding this latter detail Sharma (1980) considered Ichthydium sp. previously found in Andhra Pradesh by Rao & Mohan (1984) to be a different species, whose taxonomic status remains to be established. We agree with Sharma’s hypothesis.
