Material examined. 2 ♂, [Russia] Zabaikalie, Nizhniy Tsasutchey vicinity, sosnovyi bor, svet, 1.vii.1997 (A. Bidzilya, I. & O. Kostjuk) (gen. slide 222/19, OB) (ZMKU).
Diagnosis. Scrobipalpa intima is externally a uniformly greyish brown species with one small and two larger brown spots in the cell. It can hardly be distinguished externally from related species without studying the genitalia. Scrobipalpa punctulata is very similar but larger (13.5–16.0 mm) with more distinct brown spots. The elongate (length twice width) uncus emarginated apically in combination with the broad U-shaped posteromedial emargination of the vinculum, and nearly straight weakly curved and short cucullus are characteristic of the male genitalia. The similar species S. punctulata differs in the straight or rounded rather than apically emarginated uncus, sacculus as broad at base as cucullus (narrower than cucullus in S. intima), and deeper gap between the cucullus and sacculus. The female genitalia are recognised by the narrow, long lobes of the ventromedial depression entirely covered with foam sculpture with outwardly curved anterior tips. Scrobipalpa zagulajevi Lvovsky & Piskunov, 1989 is very similar but differs in the longer lobes of the ventromedial depression which extend distinctly beyond the anterior margin of sternum VIII.
Redescription. Adult (Figs 18, 19). Wingspan 9.8–13.0 mm. Head whitish grey, neck grey, brown-tipped; labial palpus greyish brown, palpomere 2 white on inner and upper surface; scape brown, flagelomeres brown, greyringed. Thorax and tegulae brown mixed with grey. Forewing grey uniformly mixed with brown, one small and two larger diffuse brown spots in cell, fold mottled with brown; cilia grey, brown-tipped. Hindwing and cilia grey.
Male genitalia (Figs 77, 78). Uncus twice as long as broad, weakly narrowed apically, posterior margin with short medial emargination; gnathos short, narrow, weakly curved; tegumen elongate, moderately narrow, anteromedial emargination extending to 1/3 length; cucullus of even width, weakly curved, extending to 1/2 length or to top of uncus; sacculus about as broad and 1/4–1/3 length of cucullus, outer margin with distinct medial emargination, tip inwardly curved, gap to cucullus broad and deep; vinculum twice as broad as long, anteromedial emargination broadly U-shaped, vincular process subtriangular, slightly broader at base than sacculus, tip pointed, curved otwardly, extending to tip of sacculus, gap to sacculus narrow; saccus distinctly or weakly pointed apically, extending beyond top of pedunculus; phallus weakly narrowed apically in distal portion, apex pointed, apical arm narrow, down-curved, caecum about 1/3 length of phallic tube.
Variation. Cucullus extends to 1/2 or to top of uncus; sacculus varies slightly in width from distinctly narrower at base than vincular process to subequal to latter in width; posteromedial emargination of vinculum varies from broad U-shaped to about V-shaped; saccus varies slightly in width and length being distinctly narrowed apically or about of even width, extending far or weakly beyond top of pedunculus.
Female genitalia (Fig. 130). Papillae anales subovate, sparsely covered with short setae; apophyses posteriores four times as long as apophyses anteriores; segment VIII twice as broad as long, weakly narrowed apically, posterior margin of sternum VIII broadly emarginated, anterior margin straight, strongly edged; subgenital plates weakly broadened posteriorly, 1/3 length of sternum VIII, with patches of foamed sculpture in anterolateral 1/3, lobes of ventromedial depression narrow, extending posteriorly to 3/4 length of sternum VIII, entirely covered with foam sculpture, with outwardly curved anterolateral edge, not extending beyond anterior margin of sternum VIII, separated anteriorly by deep triangular incision; apophyses anteriores straight, as long as segment VIII; colliculum moderately broad, ring-shaped; ductus bursae weakly broadened towards corpus bursae, corpus bursae subovate, signum at right side near entrance of ductus bursae, basal plate of signum narrow with two small teeth, distal hook narrow, curved at about one-half.
Biology. Adults were observed in early July in steppe biotopes.
