On the Geostiba fauna of Georgia. VII. Five new species from the Kakheti region and additional records (Coleoptera: Staphylinidae: Aleocharinae)

Abstract

Five species of Geostiba Thomson, 1858 from the Kakheti region, Northeast Georgia, are described and illustrated: Geostiba (Tropogastrosipalia) angularis spec. nov. (region to the north of Lechuri); G. (Sibiota) tbatanana spec. nov. (Tbatana Range) and G. (S.) gomborica spec. nov. (Gombori Range) of the G. bituberculata group; G. (Sibiota) bulbosa spec. nov. (Gombori Range) and G. (S.) effeminata spec. nov. (region to the south of Abano pass) of the G. carinicollis group. The distribution of Geostiba (Sipalotricha) cingulata (Eppelsheim, 1878) is revised and illustrated; a previous record from Azerbaijan is regarded as probably incorrect (result of mislabeled material). The distributions of the species of the subgenus Sibiota Casey, 1906 recorded from Georgia east of South Ossetia are mapped. Additional records of nine species are reported. The Geostiba fauna of the Caucasus region sensu lato is now represented by a total of 55 named species, 34 of which belong to the subgenus Sibiota. Twenty-six species have been recorded from Georgia.
