Eupithecia concostivexa sp. n.

( Figs 4 View FIGURES 1–6 , 10 View FIGURES 7–12 , 25 View FIGURES 22–26 )

Type material: Holotype, ♀, China, W. Sichuan, SW slopes of Erlang Shan Mt., 30 km from Luding , 29°49.39ʺ N, 102°15.08ʺ E, 21.x. 2019, 1920 m, A. Saldaitis leg. Gen. prep. J. Procházka 20172; Photo J. Šumpich 22/139 ( NMPC).

Diagnosis. This species also belongs to the proterva species group ( Inoue 1979; Mironov & Galsworthy 2014) on the basis of the structure of female genitalia. The worn state of the unique holotype does not allow a clear external diagnosis, though the very elongate discal dot is noteworthy. The female genitalia are rather similar to those of the Taiwanese E. hashimotoi Inoue, 1988 , but the colliculum is broader, the antrum membranous and the shape of the eighth tergite is different.

Description. Adult. ( Figs 4 View FIGURES 1–6 , 10 View FIGURES 7–12 ). Female. Wingspan 19.5 mm (without fringe), fore wing 11.0 mm (without fringe). Head and notum covered with greyish scales. Fore wing with slightly bowed costal margin. Ground colour pale brownish grey; transverse lines not visible; discal dot black, narrow and elongate. Hind wing with shallowly concave termen in the middle, anal area darker than rest of wing; discal dot small, ovoid. Fringes on all wings missing.

Female genitalia ( Fig. 25 View FIGURES 22–26 ). Bursa copulatrix rather ovoid, about ½ densely covered with small spines along one side from base of ductus seminalis to colliculum. Ductus bursae not expressed. Ductus seminalis broadened near base, attached to corpus bursae near anterior part. Colliculum collar-like, short and broad. Antrum membranous, relatively short and broad. Tergite A8 square. Anterior and posterior apophyses rather short and narrow. Papillae anales large, ovoid.

Male. Unknown.

Bionomy. Host plant unknown. The holotype was collected by light in the third decade of October at an elevation of 1920 m.

Distribution. China. Known only from Sichuan province.

Etymology. The name “ concostivexa ” is an anagram of the species name “ costiconvexa ”.

Note. The single type specimen is very worn.
