C o m m e n t: This recently described species was previously known only from the type locality in the Pambaki range. The new records above reveal that G. unituber is also present in the Bazumi range to the north of the Pambaki range and in the mountains to the east of Dilijan ( Map 4 ). In the latter locality, G. unituber was found together with G. tigrani . The primary sexual characters of the material from Pushkin pass are illustrated in Figs 14-20 .
