[Crustacea • 2017] Gebiacantha sagamiensis • A New Species of Upogebiid Shrimp (Decapoda: Gebiidea) from Sagami Bay, central Japan


Gebiacantha sagamiensis  Tomoyuki. 2017   


Abstract

A new species of the upogebiid shrimp genus Gebiacantha Ngoc-Ho, 1989, Gebiacantha sagamiensis, is described and illustrated on the basis of a single male specimen collected from Sagami Bay, central Japan, at depths of 101-106 m. It appears closest to G. reunionensis Ngoc-Ho, 1989, known only from La Réunion, western Indian Ocean, but the different shape of the pleomere 6 and the better developed armature of the pereopod 1 carpus distinguish the new species from G. reunionensis. Comments on the taxonomic status of Gebiacantha and Paragebicula Sakai, 2006, and on the generic assignment of the new species, are given.
