Abstract

Potamocypris narayanani n.sp. is described from a riverine habitat in Kerala, India. The new species belongs to the 'Cyprilla' group in the genus because of the wide anterior and posterior flanges on the LV. It can be distinguished from its congeners belonging to this group by the large dorsal hump on the RV, which overlaps the LV. The value of some morphological characteristics at different taxonomic levels within the genus Potamocypris is discussed and the position of the Cyprilla- group within the genus is re-assessed. Potamocypris angularis Victor & Michael, 1975 is transferred to Plesiocypridopsis. A checklist of the species of Potamocypris of the world is added, together with subjective synonymies.
