On a new species of deep-sea crab of the genus Homologenus A. Milne-Edwards, in Henderson, 1888 (Crustacea: Decapoda: Brachyura: Homolidae) from Kaua‘i, Hawai‘i

Abstract

Abstract A new species of deep-sea crab, Homologenus namakae (Brachyura: Homolidae) is described from a depth of 823 m off Kaua‘i, Hawai‘i. The new species is the first member of the genus reported from the area and can be distinguished from congeners by its carapace morphology (lack of a gastric spine, presence of prominent antennal and subhepatic spines), structure of the third maxillipeds and proportions of the ambulatory legs.
