PRESENCE OF TROGLOBITIZED JANIRIDAE (ISOPODA, ASELLOTA, JANIROIDEA) IN ANCHIHALINE CAVES OF THE BALEARIC-ISLANDS (MEDITERRANEAN) - DESCRIPTION OF TROGLOIANIROPSIS-LLOBERAI N-GEN, N-SP

Trogloianiropsis Iloberai n. gen., n. sp. is described from the floode d coastal karst of the Balearic Islands. It superficially resembles la niropsis Sars, 1897 and Janaira Moreira & Fires, 1977, but differs fro m both in some remarkable characters. It seems to be restricted to the deeper layers of anchihaline cave lakes, and shows a troglobitized mo rphology (i.e.: absence of eyes and body pigmentation, and extraordina ry elongation of antennae). Since its phyletic affinities are not clea r, its biogeographic significance and possible derivation from deep-se a or shallow-water ancestors cannot be established.
