Type material. Holotype ♂, Russia, Tuva rep., 51°43’N 94°27’E, E. Tannu-Ola mts, 700 m, Kyzyl, Nanophytonsteppe, 5–6.vi.1995 (Jalava & Kullberg) (gen. slide 311/16, OB) ( MZH).

Diagnosis. Scrobipalpa kullbergi sp. nov. is a small species with light grey forewing with diffuse brown obligue costal streak and black markings in the cell. The long parallel-sided sacculus and broad saccus are characteristic of the male genitalia. Scrobipalpa pulchra Povolný, 1967 has a somewhat similar long sacculus, but it is distinctly broadened apically rather than parallel-sided in the new species, the vincular processes in S. pulchra are very short and the saccus is much narrower.

Description. Adult ( Fig. 36 ). Wingspan 12.1 mm. Head, thorax and tegulae covered with grey, brown-tipped scales, labial palpus upcurved, off-white, with broad brown basal and medial ring, inner and upper surface of palpomere 2 light greyish white, scape brown, flagellomeres brown ringed with grey. Forewing light grey mixed with blackish grey subcostally and in subapical 1/4, fold and subcostal vein mottled with light brown, diffuse light brown oblique sreak from 1/4 of costa to mid-width, one small and two larger brown spots in cell, cilia grey, browntipped. Hindwing and cilia light grey.

Male genitalia ( Fig. 99 ). Uncus twice as long as broad, weakly narrowed apically, posterior margin with short medial emargination; gnathos short, weakly curved; tegumen moderately narrow, elongate, anteromedial emargination extending to 1/3 length; cucullus slender, weakly curved, apex broadened, weakly pointed, extending to 2/3 length of uncus; sacculus twice as broad and about 3/5 length of cucullus, parallel-sided except for rounded apically outer margin, with pointed inwardly curved tip, gap to cucullus deep and slender; vinculum twice as broad as long, posterior margin with deep basally subovate emargination, vincular processes elongate, inner margin slightly curved inwardly, tip pointed, not extending to top of sacculus; saccus broad, truncate, far extending beyond top of pedunculus; distal portion of phallus weakly narrowed apically, apex rounded, apical arm moderately stout, at right angles to phallus; caecum strongly inflated, 1/2 length of phallic tube.

Female. Unknown.

Biology. The holotype was collected in early June in Nanophyton steppe biotope at an elevation of 700 m.

Etymology. The new species is named in honour of the Finnish Lepidopterologist Jaakko Kullberg, who collected the holotype of the new species.
