The male genitalia of Singularia lesya Kovtunovich & Ustjuzhanin sp. nov. are similar to those of S. carabayus in the curved phallus, the arched saccus and the uncus, which is widened in the middle part and tapered at the apex. They are different in the strong saber outgrowths in the lower basal part of the sacculus, the rhomboid valves and the absence of finger-like processes at the valve bases. The female genitalia are distinguished by the absence of the signum and the broad lobe of the lamina postvaginalis in S. lesya sp. nov.


The species in named after Olesya Snigur.
