Comment: Ischnosoma myops is the most widespread representative of the I. spelaeum group in the Caucasus region, its confirmed range extending from Northeast Anatolia (Rize, Artvin) to central Georgia, with the easternmost record at 43°42' eastern longitude ( Map 1 View Map 1 ). The previous and above records from Göygöl (“Helenendorf ”) in Azerbaijan (see grey circle in Map 1 View Map 1 ) are far outside the confirmed range and consequently doubtful (see comment above). For other previous records see KOCIAN (1997) and SCHÜLKE (2001, 2003, 2007). SAMIN & al. (2011a, b) reported the species from Ardabil and Fars provinces, Iran. These records, however, are far outside the confirmed distributions of I. myops and of the I. spelaeum group as a whole. There is little doubt that they are based on misidentification and most likely refer to I. splendidum or I. longicorne , if they refer to Ischnosoma at all.

The above male from the environs of Batumi is remarkably small (body length 2.8 mm; length of forebody 1.3 mm). The male primary and secondary sexual characters, however, are identical to those of other males of I. myops examined.
