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 descri bed from the deep layers of an anchihaline cave lake on Cabrera (Balea ric Islands). It shares with Mysidetes Holt & Tattersall and Deltamysi s Bowman & Orsi a third thoracic limb endopodite without enlarged segm ents, and rudimentary pleopods in adults of both sexes. Nevertheless, Burrimysis differs, among other characters, in the armature and profil e of telson and uropods. Its affinities and biogeographic significance remain uncertain.
