A new species of the troglobitic bathysciine cholevids (Pholeuonopsis cvijici n. sp) has been described from the Potpećska Pećina Cave, village Potpece, near Uzice, west Serbia. This new species is clearly distinct from its phenetically close congeners in many important respects such as: the body size, the body length to breadth ratio, the shape of the pronotum, the size of the scutellum, the shape of elytra, the form of aedeagus, the different position of setae on the apex of the paramerae, and the form of the inner sac of aedeagus. The new species belongs to an old phyletic lineage of the early Tertiary origin, and is both relict and endemic to west Serbia and the Balkan Peninsula.
