Pareupithecia Mironov & Galsworthy , gen. n.

Type species: Eupithecia spadix Inoue. Gender : feminine.

Description. Adults (fig. 5). Labial palpi short, broad, sharply tapered to apices, equal or shorter than diameter of eye; basal segment with elongated scales. Frons with tuft of tight-fitting scales directed forwards. Head with broad colliculum of protruding scales and two latero-dorsal tufts of short scales behind. Antennae bipectinate in male and filiform, ciliated in female. Metathorax with two erect crests of dense short scales. Hind leg with two pairs of tibial spurs. Apodemes of the second tergite short and broad, obtuse. Venation of fore wing: R1 long, not uniting or anastomosing with Sc; areole with short, oblique transverse vein. Venation of hind wing: M3 and CuA1 arising separately from cell (fig. 10). Fore wing broad with straight costal margin, pointed apex and evenly curved terminal margin; ground colour grey to dark brown, sometimes with rusty tinge, with broad, dark brown medial area distinctly bordered by fine, black transverse lines; discal dot small but conspicuous. Hind wing broad with evenly curved termen and right angled tornus; ground colour paler with distinct transverse lines and discal dot. Underside of wings pale with distinct blackish postmedial lines and discal dots. Last abdominal segment with two lateral crests of scales at the base, developed in both sexes, especially in the female. No sexual dimorphism in the size, shape, colouration or pattern of wings.

Male genitalia (fig.19). Uncus with ovate-oblong, membranous basal part and elongate, narrow, spine-like apical part, uniapical with seta near tip at ventral side. Anal tube long, narrow, completely covered with dense setae in apical part. Tegumen narrow, covered with long setae along margins. Valve elongate and relatively broad, with slightly curved dorsal margin and narrowly rounded apex, almost completely covered with elongate setae; sacculus thickened, lightly sclerotized, covered with long setae. Transtilla connected with dorso-proximal tips of valvae and with labides at its posterior ends. Vinculum stout, short and broad, rounded. Coremata very short, rounded, placed on the lateral sides of vinculum near bases of valvae, with tufts of long setae. Labides short and broad; anterior arms of labides curved, tapered, with distinct, slightly elongate papillae, covered with long setae; posterior arms very short with two large, setaceous papillae, connected with each other at base. Juxta ovate, short and broad; calcar broad with narrow, crescent-shaped, heavily sclerotized band in the base. Aedeagus slim, slightly curved, short and relatively narrow, shorter than length of valve; ductus ejaculatorius arising almost from the middle of aedeagus. Vesica granulate, armed with ovoid, dense patch of numerous spinules and two small cornuti near ductus ejaculatorius base. Sternite A8 two biflex, broadly diverging rods, heavily sclerotized and pointed, and connected with each other by a concave band at base.

Female genitalia (fig. 29). Bursa copulatrix very large, ovate, membranous but more strongly sclerotized posteriorly, with numerous curved wrinkled striations, three chains of slim pointed spines and a small sclerotized prominence at centre of corpus bursae; inner surface of corpus bursae almost completely covered with numerous minute spines. Ductus bursae not distinguishable. Ductus seminalis very narrow; attached to corpus bursae at centre of dorsal side. Colliculum plate-like, elongate and broad, with oblique anterior margin, two spiniform horns and convex posterior margin. Antrum membranous, short and broad. Sinus consisting of two narrow sclerotized transverse branches from the middle of anterior apophyses to pointed tips of sclerotized antrum. Sternite A8 sclerotized, broad, horseshoe-shaped. Tergite A8 rectangular, small, short and broad, with narrowly sclerotized anterior margin. Apophyses very short, relatively narrow, bases of the anterior apophyses broadened. Papillae anales small, short and broad, rounded, covered with short setae.
