Oxycephalus longipes Spandl, 1927 a valid species of the genus Oxycephalus (Amphipoda, Hyperiidea, Oxycephalidae)

Abstract

This is the first description on an adult of @iOxycephalus longipes@@ Spandl, 1927. The original record was based on juvenile females. Since its description, the species has not been recorded again, hence its validity remained uncertain. The present record of two adult females from the Indian Ocean establishes its validity. The general shape and armature on the carpus and propodus of pereopods 1 and 2 resembles that of @iO. latirostris@@, but the unique shape and structure of the seventh pereopod, the cephalon, and the first antenna are sufficient to distinguish this species from its congeners
