Tomares nogelii is a small butterfly found in the Palearctic (Ukraine, Romania, Syria, Lebanon, Israel, Palestine, Turkey to Armenia) that belongs to the blues family.

The smallest species, recognizable by the hindwing beneath bluish grey ornamented with red macular bands, which are dotted with black at their edges.

— In the larger obscura Ruhl (75 e) the upperside is uniformly black-brown, except for some vestiges of red-yellow before the distal margin of the hindwing; from the Taurus and Armenia.

[now subspecies] (75 e) is a very large form from Roumania, which considerably surpasses in size even the otherwise similar obscura; found on Astragalus ponticus, on which probably the larva feeds.

— In May and June, not rare, but flying so low that it is difficult to follow the small insect with the eyes (Staudinger).
