Abstract

Croatotrechus (nov. gen.) tvrtkovici n. sp. is described from Pe}inik cave (near the town of Ogulin), and its morphological features are illustrated. The peculiar combination of characters (two dilated fore tarsomeres in the male, basolateral setae of pronotum present, unusual shape of median lobe and inner sac of aedeagus, among other things), isolates the new taxon from all other eyeless trechines known so far from the Dinaric massifs. The hypothesis of its derivation from an epigeal ancestor is discussed. Data about the distribution and ecology of the type species are also provided.
