2 NEW SPECIES OF PARAMISOPHRIA (COPEPODA, CALANOIDA, ARIETELLIDAE) FROM ANCHIALINE CAVES ON THE CANARY AND GALAPAGOS-ISLANDS

Two new species of Paramisophria, P. reducta from the Jameos del Agua lava tube, Lanzarote and P. galapagensis from an anchialine fissure on Santa Cruz, are the first records of cavernicolous arietellid copepod s. They have several advanced characters compared with their congeners , but also exhibit plesiomorphic characters such as the lack of dorsal processes on the last prosomal somite. These species may be derived f rom neritic hyperbenthic ancestral forms which first invaded caves. An emended diagnosis is given for the genus Paramisophria..
