Eva Vojnits, 1981, Acta Zoologica Academiae Scientiarum hungaricae, 27 (3–4), 407. Type species: Eva flexa Vojnits, 1981.

Description. Adults (fig. 8). Labial palpi with separate tufts of scales at the base under eyes. Frons with tuft of tight-fitting scales directed forwards. Head with double collar of scales behind eyes. Antennae in both male and female filiform. Metathorax with two erect crests of short and dense scales. 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. 16). Hind leg with two pairs of tibial spurs. Apodemes of the second tergite short and stout. Fore wing dark olive-brown with medial and postmedial lines well marked, large discal dot, and orange discal and subtornal streaks. Underside of wings paler with very distinct dark transverse lines and discal dots. The eighth abdominal segment with two lateral crests of scales at the base, developed in both sexes. No sexual dimorphism in the size, shape, colouration and pattern of wings.

Male genitalia (fig. 21). Uncus large, stout, with broad basal lobes, uniapical. Anal tube fusiform, almost completely covered by small setae (as in Eupithecia). Tegumen stout with thickened lateral margins, minutely perforated in central part. Valve short and broad with broadened and bowed dorsal margin, rounded basal corners, a large medial, transverse wrinkle on ventral margin, and a rather narrowly rounded apex; inner surface of valve covered with sparse short setae along central part only; sacculus lightly sclerotized. Transtilla broad. Juxta almost ovoid with two long, narrow, broadly diverging posterior arms (caulis). Vinculum short, with shallow medial hollow. Coremata present. Papillae on anterior arms of labides very short, thick, rounded, broadened basally and covered by sparse short setae at apices. Aedeagus relatively large and stout, ductus ejaculatorius attached to anterior end of aedeagus. Vesica armed with a large, heavily sclerotized, plate-like W-shaped cornutus, almost completely embracing the vesica at the centre, and a smaller, folded, irregular cornutus near anterior end of aedeagus. Sternite A8 large, very broad, with two short, blunt, sclerotized, broadly diverging apical horns. Tergite A8 large, triangular, basally very broad, tapered to a curved, hook-like apex; base of tergite thickened, narrowly sclerotized with very shallow medial hollow.

Female genitalia (fig. 30). Bursa copulatrix membranous, with two long curved chains of small spines, linked at their bases. Ductus bursae not distinguishable. Ductus seminalis short and narrow, attached to ductus bursae near colliculum. Colliculum elongate and very narrow. Antrum membranous. Sinus formed by two narrow transverse branches broadened to apices from apical parts of anterior apophyses. Tergite A8 almost square, with rounded posterior angles and a slightly depressed medial longitudinal thickening. Anterior and posterior apophyses narrow and short. Papillae anales relatively short and broad, rounded.

Distribution. South Western China (SE Tibet and Yunnan).
