Fig. 24

Material examined. 1 ♂, 1 ♀, Russia, S Buryatia, 51°09’N, 106°16’E, 550 m, lake Gusinoe ozero, steppe, 18.vi.2002 (K. Nupponen) (gen. slide 394/ 16♀, O. Bidzilya) ( NUPP).

Here we provide description of the hitherto unknown female genitalia.

Female genitalia ( Fig. 24 ). Papillae anales sub-ovate, sparsely covered with short setae. Segment VIII twice wider than long, medially weakly sclerotized, with two lateral honey-comb sclerotized patches; sub-ostial lobes membranous but edged anteriorly; ostium rounded with distinct medial sclerite; anterior margin of segment VIII weakly protruded anteriorly. Apophysis anterioris longer than segment VIII and half length of apophysis posterioris. Ductus bursae long and narrow, weakly broadened before corpus bursae; posterior portion as long as apophysis anterioris, strongly sclerotized laterally, with short triangular and long curved sclerites in proхimal part; corpus bursae sub-ovate; signum a narrow plate at right side near entrance of corpus bursae.

Remarks. Female genitalia of A. kerzhneri are similar to those of A. amoenella (Frey, 1882) , but anterior margin of sternite VIII is more protruded anteriorly.

Distribution. Russia: Tuva, Buryatia (new record); Mongolia (Bidzilya 2005).
