Abstract

Duvalius semecensis tarensisssp. nov. from two subterranean sites situated on Mt. Tara (western Serbia) is described, illustrated and compared with its most related congeners. It is provisionally placed in the subgenus Biharotrechus Bokor, 1922. The new subspecies is characterized by a depigmented, medium-sized body, the presence of reduced eyes, deep and complete frontal furrows, two pairs of discal setae in third elytral striae, as well as by the shape of aedeagus. It inhabits caves on Mt. Tara and is endemic of this mountain. Data on the distribution and bionomy of the new subspecies are given. Its closest relative, Duvalius (Biharotrechus) semecensis semecensis Winkler, 1926, is redescribed and we designated its holotype by monotypy. A key for the identification and an annotated catalogue of Serbian Biharotrechus and Duvalius s. str. taxa are also provided.
