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. 2594760959 2019-07-06 MNB Range, S & Assing & Schulke Georgia 2090 41.705833 Trialeti Range 19 43.502224 3 720 5 5 2594760963 2019-07-10 MNB Assing Georgia 2090 41.705833 Trialeti Range 19 43.502224 3 720 4 4
