Duvalius (Paraduvalius) petrovici sp.n. and D.(P.) sotirovi sp.n. (Carabidae: Trechinae: Trechini): Two new troglobitic ground beetles from eastern and southeastern Serbia

The following two new troglobitic trechine ground beetle species are described from two caves in eastern and southeastern Serbia: Duvalius (Paraduvalius) petrovici sp. n., from the Resavska Pećina Cave, village of Jelovac, near Despotovac, Kučajske Planine Mts., and D. (P.) sotirovi sp. n., from the Ogorelička Pećina Cave, village of Sićevo, near Niš, Svrljiške Planine Mts. The new species considerably differ from the related taxa. All important morphological characteristics of the species, along with the diagnoses and images of the taxa are presented. These represent relicts and endemics of eastern and southeastern parts of Serbia and are of great age (probably Tertiary or even before). [Projekat Ministarstva nauke Republike Srbije, br. 173038]
