Etymology: The species is named after one of its collectors, Petr Ustjuzhanin (Altai State University, Barnaul, Russia), well-known Pterophoridae and Alucitidae specialist, with many thanks for his friendship.

Diagnosis: For differences from A. aarviki and A. bernardlandryi externally and in the female genitalia, see the diagnosis under A. aarviki .

Description ( Fig. 4 ): Wingspan 29 mm. Labial palpus 4 x eye diameter, bronze brown bordered white; inner side white. Maxillary palpus basally bronze brown, apically white. Antenna filiform, with scape white, then bronze brown. Frons rounded, slightly produced, offwhite with edge bronze brown. Vertex white suffused with pale yellow laterally and with brown line medially. Patagia white with lateral edge dark brown. Tegulae dark brown with external border white. Thorax brown, off-white distally. Forewing and hindwing as in Fig. 4 and under diagnosis of A. aarviki . Forewing fringes bright silvery grey with medial band white. Underside of forewing brown medially, suffused with white elsewhere; underside of hindwing brown along costa, then white. Abdomen: first segment and anal tuft white, other segments off-white densely suffused with grey brown. Legs bronze brown with inner side white; tibial spurs small, asymmetrical, both pairs of same length.

Female genitalia ( Fig. 20 ). Papillae anales produced ventrally, densely covered with setae; lower edge not traceable, fused with ninth abdominal segment. Ninth abdominal segment sclerotized, strongly bulged dorsally. Apophyses posteriores basally only recognizable by a comma-like sclerotization, ending shortly pointed close to bases of apophyses anteriores. Abdominal segment VIII well developed, sclerotized. Apophyses anteriores short, as long as apophyses posteriores. Ostium bursae moderately enlarged, sclerotized, slightly produced. Ductus bursae half the length of corpus bursae, funnelshaped for 2/3, then cylindrical. Ductus seminalis branching off at 2/3 of ductus bursae. Corpus bursae suboval, medially bulged, with a patch of spinulae medio-ventrally.

Male unknown.
