On the taxonomic position of Indiacypridinae (Crustacea, Ostracoda), with the description of a new species of Indiacypris Hartmann, 1964 from Chalakkudy River (Kerala, India)

A new species of Indiacypris, I. chalakkudensis n. sp., is described from Chalakkudy River in Kerala, India; an asexual population of I. dispar occurred sympatrically with the new species and is here briefly redescribed. This is only the third species reported in this genus, and indeed also in the subfamily. The taxonomic position of this lineage is discussed in light of new morphological evidence. The subfamily could either belong to Cyprididae, or to Ilyocyprididae, or could represent an intermediate branch. Until molecular phylogeny can test these hypotheses, the subfamily remains in Ilyocyprididae.
