Uncus arched, tapered to apex. Right anellus arm well developed, left arm reduced. Saccus arched. Phallus narrow, slightly curved, tapered in distal part, in size 1.5 times shorter than right valva.

Female genitalia. Papillae anales triangular. Posterior apophysis robust, comparatively long, widened at apex and slightly curved. Ostium bursae situated in left part of abdomen. Corpus bursae small, oval, weakly sclerotized, without signum.

Diagnosis. With respect to wing coloration, P. boldyrevae resembles Pselnophorus hunti Ustjuzhanin & Kovtunovich 2015, from which it differs, however, in the colour of the fringe inside the cleft, the absence of a wide pale spot at the second lobe base and in the paler colour of the thorax and tegulae. In the male genitalia, the new species is also similar to P. hunti with regard to the curved harpe on the left valva, but differs in the fold on the right valva, the unequal size of the left and right valva and the distally curved phallus.

Distribution: South Africa.

Flight period: November, December.

Etymology. The species is named after Irina Boldyreva, an employee of the diplomatic service, who rendered great assistance in organizing the expedition.
