ABSTRACT. A new stygobiotic species of the genus Proasellus Dudich, 1925 (Crustacea: Isopoda: Asellidae), Proasellus abini sp.n., is described from the hyporheic habitats and groundwater of the Abin River basin, located in the southwestern foothills of the Caucasian Ridge. The new species is morphologically and genetically close to Proasellus linearis Birštein, 1967, known from the Evstafiev Sсhel (=Ashamba River) near Gelendzhik. Data on phylogeny, ecology and feeding of the species and other SW Caucasian species of the genus are also presented in the paper.

KEY WORDS: Crustacea, diversity, Proasellus, new species, hyporhea, stygobiotic, southwestern Caucasus, Russia.
