M a t e r i a l e x a m i n e d: GEORGIA: S a m t s k h e - J a v a k h e t i: 3♂♂, 5♀♀, Trialeti Range, S Bakuriani, 41°42'21''N, 43°30'08''E, 2090 m, birch trees at tree line, litter and grass sifted, 6.VII.2019, leg. Assing& Schülke( MNB, cAss); 1♂, 4♀♀, same data, but 10.VII.2019, leg. Assing(cAss).
C o m m e n t: In the original description, which is based on a unique female (erroneously sexed as a male) from "Cauc. Min. Bor., Trialetskij Chreb, Bakuriani, 1800-2200 m", PACE (1996)assigned the species to LioglutosipaliaSCHEERPELTZ, 1951, now a synonym of SipalotrichaSCHEERPELTZ, 1931. Based on a revision of the holotype, Assing (2005)treated G. zercheias a species of doubtful status and moved it to Sibiota. During a field trip to Southwest Georgia, Michael Schülke and the author succeeded in collecting a series of specimens including males in the environs of the typelocality, thus rendering a clarification of the identity of G. zercheifinally possible. An examination of the males revealed that the species does not belong to Sibiota, but to Sipalotricha. The male is characterized by a pronounced sutural carina on the elytra (unique in the subgenus) ( Fig. 9). The external and sexual characters are illustrated in Figs 8-12.
