KOROR MISTICIUS, NEW GENUS, NEW SPECIES (DECAPODA: HIPPOLYTIDAE), A CAVE SHRIMP FROM PALAU

Abstract

A new genus and species, Koror misticius, a shrimp belonging to a group of 6 monotypic genera within the Hippolytidae is described from a marine cave in Palau. It differs from Barbouria and Janicea in having arthrobranchs on the 4 anterior pairs of pereiopods and epipods on maxilliped 1, from Ligur in different placement of the "antennal spine" and in having the propodus of the 3 posterior pereiopods subdivided, and from Parhippolyte and Somersiella in having a slender rostrum and the appendix masculina distinctly longer than the appendix interna on the second male pleopod.
