Two new species of Bergrothia Reitter, 1884, with a review of the Bergrothia fauna of Georgia (Coleoptera: Staphylinidae: Pselaphinae)

Abstract

Two species of Bergrothia Reitter, 1884, a small Caucasian genus of Amauropini, are described and illustrated: B. svanetica spec. nov. (Georgia: Svaneti region) and B. simplex spec. nov. (Northeast Turkey: Ordu, Giresun). Including the new species, the genus now includes a total of nine species distributed in Georgia (six species), Northeast Turkey (three species), and Azerbaijan (one species). Based on abundant material collected during seven field trips conducted to Georgia between 2016 and 2021, the partly allo- and partly sympatric distributions of the Bergrothia species in Georgia are clarified and mapped. All of them are confined to the west of the country.
