A New Species of Heteromysis (Crustacea : Mysidacea) from a 'Blue Hole' in the Bahamas

Abstract

A new species of Heteromysis is described from a blue hole on Grand Bahama Island. It is distinguished by having a single inner spine on the uropod endopod, 9 to 10 uniformly distributed spines on the lateral margins of the telson, and spination of the whole distal emargination of the telson. Modified setae distally on the third segment of the peduncle of the first antenna, as characteristic of the subgenus Olivaemysis, are present only in the female, while the male pleopods are typical of the subgenus Heteromysis.
