Supplementary description of Pontharpinia robusta Gurjanova, 1938 (Crustacea: Amphipoda: Phoxocephalidae)

Abstract

The original description of Pontharpinia robusta Gurjanova, 1938 is supplemented for the first time by descriptions and illustrations of the main diagnostic characters: the shape of rostrum and lower antennal angle, and the morphology of mandible, uropod 3 and telson. Major diagnostic characters were compared to those of the type specimen. A long, downward-tapering process on the lower antennal angle, reported in the original description, was shown to be absent both in male and female specimens of this species.
