Three new cave-dwelling trechine ground beetles from eastern and southeastern Serbia (Coleoptera: Carabidae: Trechinae)

Three new troglobitic trechine ground beetle species are described from three caves in eastern and southeastern Serbia: Duvalius (Paraduvalius) bogovinae sp. n., from the Bogovinska Pecina Cave, village of Bogovina, Kucajske Planine Mts., near Boljevac, eastern Serbia; D. (P. ) milutini sp. n., from the Samar cave system, village of Kopajkosara, Mt. Kalafat, near Svrljig, southeastern Serbia, and D. (P. ) beljanicae sp. n., from the Velika Atula Cave, village of Strmosten, Mt. Beljan- ica, near Despotovac, eastern Serbia. The new species are easily distinguished from relatives. All important morphological features, along with the diagnoses and illustrations of the new taxa are presented. The new species are relicts and endemics of eastern and southeastern Serbia. They probably belong to old phyletic lineages of Tertiary or even pre-Tertiary origin.
