Distribution. Caucasus ( Potapov, 2001). This species is reported for the first time from Iran.

Diagnosis. The identification of the species was done according to Potapov (2001) as below: Body length about 1 mm and the colour is blackish blue. Dorsal integument with rather weak reticulation, on Abd. V much stronger ( Fig. 3A). Eye-patches with 8+8 ommatidia. PAO is 2 times as long as the diameter of the ommatidium. Claw without the inner tooth. Empodium is reduced, shorter than ¼ of the inner edge of the claw on the legs of all pairs ( Fig. 3C). Tibiotarsi with distinctly clavate hairs. Th. I-III with 1+1, 1+1, 3-6+3-6 ventromedial setae, tenacular area (a small organ, appended to the third abdominal segment, which holds the furcula in position under the abdomen) with 3–4 area ( Fig. 3D).

Remarks. In the original description of the species, Ant. IV was mentioned with a distinctly divided apical bulb, but in specimens found in this study, the apical bulb on Ant. IV is simple ( Fig. 3B).
