ALEXEY V. SHAVRIN

The brevicollis species group of the genus Geodromicus Redtenbacher, 1857 is reviewed. All three Western Palaearctic species of the group, including G. alborzensis sp. n. (North Iran: Alborz Mts.), G. brevicollis Fauvel, 1875 (Caucasus, north-eastern Turkey, north-western Iran) and G. transversus Motschulsky, 1860 (Caucasus) are(re-) described and illustrated. The following new synonymies are established: Geodromicus Redtenbacher, 1857 = Brachydromicus Bordoni, 1993 syn. n., G. brevicollis = G. jarrigeanus Fagel, 1976 syn. n., = G. jarrigeanus ziganensis Coiffait, 1978 syn. n., = G. armeniacus Iablokoff-Khnzorian, 1989 syn. n., and G. transversus = G. flavipes Motschulsky, 1860 syn. n. The following synonymies previously established by Iablokoff-Khnzorian (1989) are confirmed: G. brevicollis = G. latiusculus Eppelsheim, 1878, = G. constricticollis Eppelsheim, 1890. A lectotype of G. constricticollis is designated. A key to species and distributional maps of all species are provided. Two species represent new country records: G. brevicollis for Azerbaijan and Iran, and G. transversus for Georgia and Armenia.
