(Figs. 1, 6, 7, 11)
Diagnosis. Externally the new species is similar to P. argenta Solovyev & Saldaitis, but differs from the latter by the absence of silver scales and dark base on forewings. It is related to P. hoenei Solovyev & Saldaitis in male genitalia, but can be distinguished by the shorter length of the lobes of the uncus and the base of valva with an acute tornal corner. In the female genitalia, this new species is characterized by the longer ductus bursae and with the bisignate signum in the corpus bursae. In P. argenta Solovyev & Saldaitis and P. erlanga Solovyev & Saldaitis, the signa are composed of several small stellate sclerites.
Forewing length 11.0–12.0 mm. Head white, with scattering of yellowish brown scales. Antenna yellowish brown, ringed with white hair at base. Labial palpus yellowish brown. Legs blackish brown to brown, a white spot at femur base, each tarsomere ringed with pale white; hind tibia with 2 pairs of spurs and with dense long hair; pretarsus black. Prothorax dark brown. Pterothorax white, with scattering of brown scales. Forewing with R2 separated, R3-5 stalked. Hindwing with M1 and Rs stalked; Sc + R1 anastomosed with anterior edge of cell near base. Forewing blackish brown; antemedial fascia indistinct; postmedial fascia consisting of series of white rounded spots and a discal spot; terminal area grayish white, with proximal border running from 3/4 costa almost to the tornus, with dark brown streak on costa; fringe brown, with rare tufts of white scales.
Male genitalia (Figure 6). Uncus bilobed, horn-shaped, less than valva in length, each lobe same as distal part of valva in size and slightly curved; gnathos reduced to sclerotized band connecting both lobes of the uncus; valva square-shaped proximally, with acute tornal corner and with long sickle-shaped distal part; saccus short; aedeagus almost straight, with longitudinal incision running from aedeagus apex to basal third.
Female genitalia (Figure 7). Ovipositor lobe flattened, foot-shaped; anterior apophysis short, triangular; posterior apophysis long and slender; vaginal plate large, spinulate; antrum short, strongly sclerotized; ductus bursae slightly spiraled, with pair of medial strongly sclerotized longitudinal ribbons; corpus bursae ovoid, with bisignate signum.
