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

Abstract

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 Pecina Cave, village of Jelovac, near Despotovac, Kucajske Planine Mts., and D. (P.) sotirovi sp. n., from the Ogorelicka Pecina Cave, village of Sicevo, near Nis, Svrljiske 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).
