Type material.

Diagnosis.

Scrobipalpa punctulata sp. n. externally does not show any diagnostic characters to separate it from congeneric species. The male genitalia are close to those of S. triangulella sp. n., S. reiprichi Povolný, 1984 and S. corleyi Huemer & Karsholt, 2010, but the vincular process is narrower, the gap to the sacculus is larger, the valva is shorter and the saccus is narrower; S. reiprichi has the uncus narrower, the sacculus and saccus broader; S. corleyi differs in a broader uncus and broader vincular process.

Description.

Adult (Figs 2, 3) Wingspan 12.0-15.0 mm. Head, thorax and tegulae grey, frons light grey, labial palpus grey mottled with black, inner surface of segment 2 off-white, scape grey, other antennal segments grey with narrow light grey basal rings; forewing plain greyish-brown, basal half of subcostal vein and fold yellowish-white, black spots in cell indistinct, cilia grey black tipped; hindwing and cilia grey.

Male genitalia (Figs 16, 17) Uncus elongated, posterior margin weakly emarginated; gnathos short, slender, weakly curved; tegumen broad, anteromedial emargination deep, broadly rounded; valva moderately narrow, nearly straight, weakly constricted in middle, apex rounded, extending to the top of uncus or slightly shorter; sacculus ca. 1/4 length of valva, outer margin rounded with pointed inwardly curved tip, gap to vincular process narrow; vincular processes slightly shorter than sacculus, distal portion narrow, apex with outwardly curved tip; posterior margin of vinculum with deep v-shaped medial emargination; saccus narrow, tapered, slightly extending beyond top of pedunculus; phallus of moderate width, straight, apical arm narrow, sinuous, caecum weakly inflated, 1/3 length of phallus.

Variation. Sacculus and vincular process vary slightly in width.

Female. Unknown.

Distribution.

China (Henan, Shanxi).

Biology.

Host plant unknown. Adults were collected in late May and July at altitudes of 1200-1450 m.

Etymology.

The species name is derived from the Latin adjective punctulatus (having small spots), referring to the spots on the forewing.
