Mironov, Vladimir & Šumpich, Jan, 2022, New species of the genus Eupithecia (Lepidoptera, Geometridae) from China Part IX, Zootaxa 5219 (3), pp. 276-286 : 281-282

Eupithecia voraria sp. n.

( Figs 5 , 11 , 18 )

Type material: Holotype, ♂, China, Yunnan, Tse-Kou , 2000 m, 28°02ʹ N, 98°54ʹ E, 5.-10.vi.2011, J. Klír leg. Gen. prep. J. Procházka 20189; Photo J. Šumpich 22/127 ( NMPC).

Diagnosis. Fore wings with more or less clear brownish transverse lines, and species rather similar externally to Eupithecia eremiata Šumpich & Mironov, 2022 , but hind wings lighter. The male genitalia are rather similar to those of Eupithecia molestissima Vojnits, 1981 . However, the sternite A8 is narrower and longer than in this species. The wings are also narrower and lighter than in Eupithecia molestissima Vojnits, 1981 ( Mironov & Galsworthy 2014, Plate 6, fig. 155).

Description. Adult. ( Figs 5 , 11 ). Male. Wingspan 19.0 mm, fore wing 10.5 mm. Head and notum covered with greyish scales. Fore wing narrow, elongate; costal margin slightly curved; apex narrowly rounded. Ground colour ochreous brownish; transverse lines faintly marked; terminal line dark brown, interrupted by veins; discal dot dark brown, ovoid. Hind wing ovoid, pale brownish, darker along anal margin. Fringes on all wings chequered whitish brown and brown.

Male genitalia ( Fig. 18 ). Valve narrow, with small, blunt ventral process weakly curved dorsal margin and tapered apex; sacculus sclerotized. Papillae on the anterior arms of the labides large, broad, clavate. Vinculum rather short and narrow. Aedeagus broadened to anterior end. Vesica armed with one slim, long horn-like cornutus, one shorter horn-like cornutus, an elongate plate-like cornutus and numerous minute spicules. Sternite A8 peg-like, tapered to posterior end, with two short apical horns and elongate basal lobes; basal hollow deep.

Female. Unknown.

Bionomy. Host plant unknown. The holotype was collected by light in the first third of June at an elevation of 2000 m.

Distribution. China. Known from Yunnan province.

Etymology. From latin word “vorar”–“devour” in english.

Note. Uncus, anal tube and tegumen are absent in the genitalia slide.
