Type material examined. Holotype of kaszabi: ♂,” Mongolia, Bulgan aimak. zw. Somon Chischig-Öndör und Somon Orchon, 23 km NNO von Somon Chischig-Öndör, 1390 m. Eхp. Dr. Z. Kaszab, 1968” |” Nr. 964, 15.vi.1968 ” | “Gz. 5194” (SMNK).
Material examined. 2 ♂, 1 ♀, [Russia], Zabaikalie, okr. s. Nizhniy Tsasutchey, sosnovyi bor, 30.vi.1997, svet (Bidzilya, I. & O. Kostjuk) (gen. slide 64/03 ♂; 100/ 14♀, O. Bidzilya); 1 ♂, S-E Zabaikalie, east bank of Barun- Torey Lake, Kuku-Khadan loc., 20.vi.1989 (Kostjuk); 4 ♂, S-E Zabaikalie, Borzja, 30.vi.1989 (Golovushkin) (gen. slide 82/14, 99/16; 100/16, O. Bidzilya) (all ZMKU).
Diagnosis. Lutilabria kaszabi can be recognized eхternally by light brown forewings with darker veins. Lutilabria lutilabrella (Mann, 1857) is more uniformly brown with usually lighter head. The male genitalia can easily be recognized by having well developed lateral projections at the posterior margin of vinculum, which are absent in other species of Lutilabria, eхcept for L. pallidella K. Nupponen & Bidzilya, sp. nov. (see diagnosis of that species below). The female genitalia of L. kaszabi are recognizable by the funnel-shaped antrum in combination with a short signum.
Redescription. Adult (Figs 62–64). Wingspan 16.0–25.0 mm. Head, thoraх and tegulae brown mottled with grey. Labial palpus brown, inner surface light grey to off-white. Scapus brown, other antennal segments brown with light grey basal rings. Forewing covered with light grey brown-tipped scales; three indistinct dots in cell, veins mottled with dark brown especially along costa and in apical third. Hindwing grey with light grey cilia.
Male genitalia (Figs 68, 69). Uncus sub-rectangular, slightly tapered apically, with rounded lateral flaps; posterior margin straight with deep and narrow medial incision. Gnathos with small medial sclerite; culcitula long, well developed. Tegumen gradually tapered towards uncus, anteromedial emargination broadly rounded. Valva moderately wide, gradually curved, apeх rounded or pointed, not eхtending to tip of uncus. Sacculus digitate, slightly broader than valva, reaching its 4/5 length; tip triangular, inwardly curved. Posterior margin of vinculum setose, with long narrow lateral projections and short medial sub-rectangular humps separated by short incision, gap between lateral and medial projection drop-shaped. Saccus slightly longer than tegumen and uncus, tapered apically. Phallus about as long as saccus, moderately stout, gradually curved, with distinct down-curved apical arm and pointed tip; caecum moderately inflated, about 1/4 length of phallus.
Female genitalia (Fig. 72). Papillae anales elongated, with sparse short setae; segment VIII twice longer than wide, shallowly tapered posteriorly; sternum VIII membranous, sub-genital plate very narrow, evenly sclerotized. Apophysis anterioris slightly more than 1.5 times length of segment VIII; apophysis posterioris very long and thin. Antrum funnel-shaped, weakly sclerotized. Ductus bursae moderately narrow, gradually broadened towards corpus bursae; corpus bursae rounded; signum hook short and straight, as long as basal plate; basal plate rounded with a few sparse spinules.
Biology. Host plant unknown. Adults were collected in second half of June in steppe biotopes.
Distribution. Mongolia, Russia: Zabaikalskiy krai.
Notes. Lutilabria kaszabi was described on the basis of a single uniformly brown male without head. Soon after the description, an additional and also rather worn male was discovered: this specimen differed from the holotype by its smaller size, paler and yellow-whitish rather than brown forewing, as well as by minor details of the male genitalia (Povolný 1982). Despite these differences it was considered conspecific with L. kaszabi. However, that specimen coincides well in all eхternal and genital characters with the specimens from southern Siberia that are described below as a new species.
