A new deep-sea genus and species of Eriopisidae (Crustacea: Amphipoda: Senticaudata) from the Gulf of Mexico

ABSTRACT

A new monotypic genus of eriopisid amphipod Bathypisella gen. nov. is described and illustrated. The specimens were collected on sediments from the southern Gulf of Mexico, at 884 m depth, aboard the R/V Justo Sierra. The new eriopisid herein described differs from other genera mainly by bearing coxae 1–7 with a posteroventral notch; pleonal and urosomal segments dorsally toothed, and without setae; pereopod 7 basis narrow; and telson with 2 robust setae dorsally. The new genus and species increase the number of eriopisid genera recorded to 19 worldwide, and the deep-sea benthic amphipods (below 200 m) from the Gulf of Mexico to 20.
