Geostiba (Sibiota) carinicollis ( EPPELSHEIM, 1878) ( Map 2 )

Leptusa carinicollis EPPELSHEIM, 1878: 95 f.

C o m m e n t: The original description is based on an unspecified number of syntypes, partly from unspecified localities ("im Kaukasus weiter verbreitet"), but "hauptsächlich bei Mamudly ... und auf den Irgan-Tschaisky-gara" ( EPPELSHEIM 1878). The type material in the Eppelsheim collection was revised and a male from "Mamudly" was designated as the lectotype by ASSING (2005), who identified the type locality as a place in the Baku region, Azerbaijan, in the East Caucasus. A re-examination of the data indicated in Leder´s travel reports in SCHNEIDER & LEDER (1878), however, revealed that Mamudly is situated in the south of Georgia, close to the border with Armenia, and most likely identical to Mtisdziri (=Makhmutlo, =Mamudlo, =Mamutlo; 41°17'12''N, 44°10'08''E) in Kvemo Kartli province. The second specified locality ("Irgan-Tschaisky-gara") are probably the mountains (gara) near Irgani (=Irganchay, =Irganchai, =Irganchaj; 41°12'24''N, 44°08'24''E), which are not far away from the type locality. The revised, currently known distribution is shown in Map 2 .

As can be inferred from the morphology of the median lobe of the aedeagus (base abruptly convex in lateral view; see figure 190 in ASSING 2005), G. carinicollis is closely allied to the four species described from Armenia below).
