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).
