Scrobipalpa latiuncella sp. n.

( Figs. 2 , 18 )

Type material. Holotype, 3, China: Suyukou, Mt. Helan (38°30' N, 106°06' E), Ningxia Hui Autonomous Region, 2000 m, 10.viii.2005, leg. Xinpu Wang et al., genitalia slide no. 101/08.

Description. Adult ( Fig. 2 ): Wingspan 7.0 mm. Head, thorax and tegula grey mottled brown; frons cream. Labial palpus upcurved; segment 2 grey-brown, outer surface cream; segment 3 light brown, with black medial belt, white at apex. Scapus black, other antennal segments black with narrow basal grey rings. Forewing with light grey, black-tipped scales concentrated mainly along costal margin; black spot at twothirds near dorsal margin; small black spot at base of cell and prolonged black spot at corner of cell; ochreous scales along veins, mainly in basal half; cilia light grey, with some black-tipped scales. Hindwing and cilia grey.

Male genitalia ( Fig. 18 ): Uncus large, gradually broadened distally. Gnathos weakly curved. Tegumen with basal part broad, distal part moderately narrow. Valva narrow, apically pointed, far exceeding top of uncus. Sacculus parallel-sided, relatively slender; apex rounded, with small pointed tip. Paired processes on posterior margin of vinculum short, relatively broad, sub-triangular, with outwards curved tip; medial excision small, nearly U-shaped. Saccus short, narrow, pointed apically. Aedeagus weakly flattened basally; distal portion straight, with distinct apical cornutus.

Female: Unknown.

Diagnosis. Scrobipalpa latiuncella sp. n. is characterized externally by the greyish-black forewing with prominent black spots and ochreous veins. The male genitalia can be easily differentiated by the long and narrow valva in combination with large, apically widened uncus.

Biology. Host-plant unknown. The holotype was collected in early June at 2000 m altitude.

Distribution. China (Ningxia).

Etymology. The specific name is derived from the Latin latus – broad, referring to the broad uncus in the male genitalia.
