Eupithecia khama sp. n.

( Figs 6 , 12 , 26 )

Type material: Holotype, ♀, China, NW Sichuan, near Maniganggo , 31°47ʹ22ʺ N, 99°23ʹ27ʺ E, 30.6. 2019, 3860 m, R. Butvila & A. Saldaitis leg. Photo / Gen. prep. J. Šumpich 22/137 ( NMPC).

Diagnosis. This species similar externally to Eupithecia quadripunctata Warren, 1888 and Eupithecia fatigata Vojnits & de Laever, 1978 according to narrow, elongate wings with elongate and narrow discal dots. Eupithecia khama sp. n. might belong to the fletcherata species group ( Bolte 1990) on the basis of the presence of a row of spines in the bursa copulatrix. The female genitalia can be distinguished from those of other species by the combination of shape of bursa, position of spines, shape of ductus seminalis and the large papillae anales.

Description. Adult. ( Figs 6 , 12 ). Female. Wingspan 22.5 mm (without fringe); fore wing 12.5 mm (without fringe). Head and notum covered with greyish scales. Fore wing elongate, costal margin slightly bowed. Ground colour pale greyish brown; transverse lines not visible; discal dot narrow, elongate. Hind wing ovate, paler than fore wing; anal margin darker than rest of wing; discal dot dark, narrow and elongate. Fringe missing in type specimen.

Female genitalia ( Fig. 26 ). Bursa copulatrix relatively small, broadened at anterior part, densely covered with spines in posterior part, and with smaller area covered with more sparse spines and curved row of spines in anterior part of bursa. Ductus seminalis broadened basally, curved, attached to medium part of corpus bursae. Colliculum collar-like, rather short and broad. Antrum membranous, broadened posteriorly. Tergite A8 large, quadrate. Anterior and posterior apophyses narrow. Papillae anales relatively large, broad, with rounded apices.

Male. Unknown.

Bionomy. Host plant unknown. Type material was collected by light in late June at an elevation of 3860 m.

Distribution. China. Known from Sichuan province.

Etymology. The species name is derived from the name of the historical region of Kham in Tibet in which the type locality Maniganggo is located.

Note. The single type specimen is very worn.
