On the status of some species of the genus Trichoniscus Brandt, 1833 (Isopoda: Oniscidea: Trichoniscidae) in the fauna of Serbia

Abstract

Synonymy has been established for the three taxa, Trichonsicus serboorientalis Pljakić, 1977 T. bononiensis timocensis Pljakić, 1977 and T. bononiensis sotirovi Pljakić, 1977, with previously described troglobiotic species T. bureschi Verhoeff, 1926 and T. bononiensis Vandel, 1965. Known localities for T. bureschi and T. bononiensis in Serbia are listed and an approximate distribution map of both species is presented. Trichonsicus bureschi is treated as a younger troglobiont, and not as a troglophile. The closely related group of Trichonsicus species, „inferus“ group, is expanded and its distribution is presented on the map.
