A Revision Of The Deep-Sea Porter Crabs Of The Genus Gordonopsis Guinot & Richer De Forges, 1995 (Crustacea, Decapoda, Brachyura, Homolidae), With Descriptions Of Five New Species

For the century to 2018, only one species of the deep-water porter crab Gordonopsis Guinot & Richer de Forges, 1995 (Brachyura, Homolidac), the type species, G. profundorum (Alcock & Anderson, 1899), was known, and only fmm a handful of specimens from the Indian Ocean. In 2019, two species were described from the eastern Indian and western Pacific Oceans. The present revision of available material, most of which was only collected in the last decade, adds five new species to the genus. This explosion in species numbers demonstrates just how poor our understanding is of deep-sea habitats and their constituent fauna.
