The rousi species group of the genus Geodromicus Redtenbacher, 1857 (Coleoptera: Staphylinidae: Omaliinae)

Abstract

The rousi species group of the genus Geodromicus Redtenbacher, 1857 is reviewed. All four Western Palaearctic species of the group, including G. (s. str.) puncticollis (Weise, 1875) (Europe), G. (s. str.) anlasi sp. n. (north-eastern Turkey), G. (s. str.) lobanovi sp. n. (Iran: Alborz Mts.) and the Caucasian G. (s. str.) rousi Bordoni, 1984 are (re-)described and illustrated. The following new synonymies are established: G. (s. str.) puncticollis = G. schubertorum Scheerpeltz, 1937, syn. n. = G. robusticornis Bernhauer, 1941, syn. n. = G. montenegrinus Bernhauer, 1941, syn. n. A key to species and distribution map are provided. Two species are recorded for the first time: G. puncticollis from Albania, and G.rousi from North Ossetia – Alania and Dagestan in Russia, as well as from Georgia
