A New Species of the Bathypelagic Shrimp Genus Pasiphaea Savigny, 1816 (Crustacea: Decapoda: Caridea) from Off Hawaii, Central Pacific

Abstract

A new species of bathypelagic shrimp of the family Pasiphaeidae, Pasiphaea dorsolineatus (Caridea), is described on the basis of a single female specimen from off Hawaii, Central Pacific. It is distinguished from the 61 congeners by the following combination of characters: carapace dorsally non-carinate; abdomen without posterodorsal tooth on any somite, second to sixth abdominal somites sharply carinate dorsally; posterior margin of telson very slightly concave; and merus of first pereopod armed with 1 or 2 ventral spines. The new species is the sixth known of the genus, Pasiphaea Savigny, 1816, from the Central Pacific region.
