The male genitalia of Singularia sinjaevi Kovtunovich & Ustjuzhanin   sp. nov. resemble those of S. walsinghami   , but differ from them by the narrow, long rod-like anellus arms whereas those of S. walsinghami   are shorter and angulate. The phallus of the new species is strongly thickened and bent at a right angle in the basal part, whereas the phallus of S. walsinghami   is almost straight.


The species is named after Viktor Synjaev, the prominent Russian traveller and entomologist, who collected this species.
