Ten further genitalia preparations preserved in glycerol.  
 Remarks. The original description of F. autocrossa (Meyrick, 1937) is based on four specimens of both sexes. The genitalia preparation of the lectotype (a male labelled “Thaishan, China, H. 5,000, VI. [19]34, slide no. BM-8277”, BMNH) was examined. A single paralectotype (a female labelled “Tai-Shan, Prov. Shantung, 13.VI.1934, slide. no. CIS–4232/Park”) is preserved in the Caradja collection, and the female genitalia were illustrated by Park (1998). The ribbon-shaped sclerotizations of the aedeagus as well as curtain fringes on the underside of the hindwings in male specimens indicate a close relationship to F. spurcella (Duponchel, 1843) and F. transsilvanella Z. Kovács & S. Kovács, 2001. Habitually F. autocrossa most resembles F.spurcella, but differs from that by the ochreous brown labial palps and ochreous frontal part of the head. In the male genitalia a wing-shaped lateral lobe of the aedeagus separates F. autocrossa from the other known species of the genus. In the female genitalia a strongly sclerotized and conspicuous antrum is characteristic. The adult flies in June and comes to artificial light. A second generation appears occasionally in August. The habitats are different kinds of steppes. A redescription of this poorly known species is given below, as well as notes on its known distribution. Olschwang et al. (2004) first reported this species from Europe based on this material.   
 Description (Fig. 38). Wingspan 17–20 mm. Head grey, mottled with brown, face distinctly ochreous. Thorax and tegulae dark greyish brown. Abdomen ochreous grey. Labial palp ochreous, mottled with browntipped scales; segment II laterally broad, length 1.5x diameter of eye; segment III thin, as long as segment II. Forelegs dark brown, mid- and hindlegs basally ochreous, more or less with scattered brownish scales. Forewing dark brown; black spot at middle of fold and two further spots at cell, all surrounded by a few ochreous brown scales; subapical and dorsal spots indistinct; fringe fuscous, basal half with scattered dark brown scales forming more or less distinct broad fringe line. Hindwing fuscous, underside with curtain fringe along the radius. Female somewhat smaller than male and without curtain fringe on hindwing underside.   
 Male genitalia (Fig. 39). Uncus moderately narrow, 2x as high as broad, distal margin rounded with slight medial incision. Gnathos-hook short and curved, relatively broad. Valva short and narrow, almost straight. Sacculus almost as long as valva, basal part laterally broad, apex pointed, laterally thin and vertically with broad projection. Saccus 2x longer than broad, apex cut off. Aedeagus without cornuti, almost as long as tegumen and uncus together; caecum very broad, anteriorly rounded, distal part slender, slightly longer as caecum, one side with ribbon-shaped sclerotizations extended towards apex, another side with wing-shaped strongly sclerotized serrate lobe; near apex large, membranous, medially sclerotized patch.   
 Female genitalia (Fig. 40). Antrum large, subrectangular, strongly sclerotized plate, anterior margin medially prolonged and apex laterally curved inwards, lateral margins strongly turned inwards and medially wrinkled. Colliculum strongly sclerotized, posteriorly broader, as long as antrum, anteriorly wide with small spines. Ductus bursae short, ductus seminalis with a separate small bursa. Corpus bursae large and membranous. Signum an arched plate with small posterolateral processes; shanks thin; posteriorly extended and less sclerotized. Apophyses anteriores moderately short and thick. Apophyses posteriores very thin, 3.5x length of apophyses anteriores. Segment VIII with large semicircular lateral patches.   
 Distribution. Described from China. Widely distributed in the southern Ural Mountains, recently found also from lower Volga region and the Altai Mountains (K. Nupponen, unpublished). Additionally recorded from Tuva and Chita regions (Bidzilya 2000) and the Krasnoyarsk region.
