Burrimysis palmeri, a new genus and species of Heteromysini (Crustacea: Mysidacea) from an anchihaline cave lake of Cabrera (Balearic Islands, Mediterranean)

Burrimysis palmeri, a new genus and species of Heteromysini, is described from the deep layers of an anchihaline cave lake on Cabrera (Balearic Islands). It shares with Mysidetes Holt & Tattersall and Deltamysis Bowman & Orsi a third thoracic limb endopodite without enlarged segments, and rudimentary pleopods in adults of both sexes. Nevertheless, Burrimysis differs, among other characters, in the armature and profile of telson and uropods. Its affinities and biogeographic significance remain uncertain.
