Diagnosis.

Hoploscopa brunnealis displays a forewing pattern very similar to that of H. danaoensis sp. nov., with a median pale yellow Y, a postmedian pale yellow patch invaded with brown or tawny and a pale yellow subterminal line. In female genitalia, the antrum sclerotisation is short, the ductus bursae is short, straight, and the corpus bursae is pear-shaped, with a small straight thorn. Male genitalia are not known.

Similar species.

Hoploscopa danaoensis sp. nov., H. metacrossa (q.v.), H. parvimacula sp. nov. (q.v.). Female genitalia of these species display a larger antrum sclerotisation.

Description.

Head. Antennae dorsally with bronze scales. Proboscis pale brown to pale yellow. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.

Thorax (Fig. 21 ). Forewing length: 10 mm; ground colour brown; basal dash dark brown distally pale yellow; costal field tawny; median discoidal stigma and median cubital patch forming together a pale yellow-coloured Y, with basal and distal edges dark brown; postmedian patch tawny speckled with pale yellow, distally pale yellow, with costal pale yellow blotch; postmedian area suffused with pale yellow; subterminal line pale yellow; fringes brown, with pale yellow dots.

Male genitalia. Not known.

Female genitalia (N = 1) (Fig. 103 ). Anterior apophyses without dorsal bump at posterior 1/3, Antrum sclerotisation short. Ductus bursae of medium length, slender, more or less straight. Corpus bursae pear-shaped, with posterior half reticulated, anterior half membranous, with faintly marked sclerotisation between thorn and corpus opening, medially with faintly marked sclerotised band. Thorn small, straight, with small dents pointing toward thorn base.

Distribution.

Recorded from West Java (Indonesia) at an altitude of 1,300 m.

Remarks.

Nuss (1998) transferred this species from Eudorina to Hoploscopa and designated the lectotype. Argyria xiphotoma Meyrick, 1938 is synonymised with Hoploscopa brunnealis in the same paper.
