Abstract

Kotumsaridae, a new family of amphipod crustaceans is described from Kotumsar Cave in the state of Chhattisgarh, India. The family is based on Kotumsaria bastarensis, new genus and species, which is the only known member of the new family recorded to date. Although the new family appears to share some morphological characters with several other taxa from the southern hemisphere considered members of the superfamily Crangonyctoidea, including the New Zealand endemic genus Paracrangonyx, both its taxonomic and phylogenetic affinities remain unclear. Specimens of the new taxon, measuring just over 2 mm in length, were collected from the sediments of a pool in Kotumsar Cave but are believed to have migrated from deeper interstices. Kotumsaria bastarensis is only the third subterranean amphipod recorded to date from the Indian subcontinent.
