Sažetak
A new copepod species, Stephos grieveae, is collected from an anchialine cave on the Island Mljet (Croatia). The new species is distinguished from other Stephos spp. by a combination of the following features: last pedigerous somite symmetrical, female genital double-somite symmetrical in ventral view, about as long as wide, single operculum ; antennules of both sexes are symmetrical, 24-segmented and very long, reaching almost to end of anal somite ; antennal exopod 7-segmented ; maxillule displays 13 armature elements on praecoxal arthrite ; female fifth legs symmetrical, uniramous and 3-segmented, terminal segment very long armed with spinules distally along inner and outer margin, single small spine on anterior surface and spiniform process laterally ; male fifth legs are uniramous and asymmetrically, right leg 4-segmented and left 5-segmented, segment 4 not swollen and segment 5 simple, crescent shaped, and is connected to segment 4 at approximately one quarter of its length. The shorter part tapers into a heavy process, while longer part forms a club-shaped, curved extension.
