Seven new troglobitic species of the genus Duvalius Delarouzée, 1859 (Coleoptera: Carabidae: Trechinae) from Eastern and Southeastern Serbia

Abstract

Seven new troglobitic trechine ground beetle species of the subgenus Paraduvalius Knirsch, 1924 (genus Duvalius Delarouzée, 1859) have been recently described from caves in Serbia. Five of them inhabit underground habitats in the eastern part of the country: Duvalius (Paraduvalius) trifunovici Vrbica, S. Ćurčić, Antić & B. Ćurčić, 2013, from the Mandina Pećina Cave, Kučajske Planine Mts., D. (P.) rtanjensis Vrbica, S. Ćurčić, Antić & B. Ćurčić, 2013, from the Golema Porica Pit, Mt. Rtanj, D. (P.) bogovinae S. Ćurčić, Vrbica, Antić & B. Ćurčić, 2014, from the Bogovinska Pećina Cave, Kučajske Planine Mts., D. (P.) beljanicae S. Ćurčić, Vrbica, Antić & B. Ćurčić, 2014, from the Velika Atula Cave, Mt. Beljanica, and D. (P.) petrovici S. Ćurčić, Vrbica, Antić & B. Ćurčić, 2014, from the Resavska Pećina Cave, Kučajske Planine Mts. Additional two new species live in cave habitats in southeastern Serbia: D. (P.) milutini S. Ćurčić, Vrbica, Antić & B. Ćurčić, 2014, from the Samar cave system, Mt. Kalafat, and D. (P.) sotirovi S. Ćurčić, Vrbica, Antić & B. Ćurčić, 2014, from the Ogorelička Pećina Cave, Svrljiške Planine Mts. All taxonomically important morphological characters of the habitus and the genital structures were described and compared. These are relicts and endemics of the Carpatho-Balkan mountain system and are ancient taxa.
