Diagnosis.
The large median dorsal patch with costal margin rounded on the forewing is unique to H. triangulifera . In male genitalia, the gnathos shows no distal projection, and the saccus is broad, quadrangular. In female genitalia, ductus bursae is short and slender, corpus bursae is large, globular, and bears a long curved thorn.

Description.
Head. Antennae dorsally pale yellow. Proboscis brown. Maxillary palpi brown, inner side pale brown. Labial palpi brown, ventral base pale yellow, inner side pale brown.
Thorax (Fig. 31 View Figures 19–33 ). Thorax brown, dorsally pale yellow. Collar pale yellow. Forewing length: 7-8 mm (♂), 8-9 mm (♀); forewing ground colour brown; basal and distal discoidal stigmata dark brown; median discoidal stigma forming roughly defined white X; median cubital patch elliptic, dark brown with white edges; large median dark brown patch on dorsum with rounded pale yellow costal margin; postmedian patch triangular, dark brown; postmedian line pale yellow, marked on costal half; pale yellow and brown postmedian fascia on costal half in some specimens, edged distally by white subterminal line; fringes brown with white spots. Hindwing pale brown. Forelegs bronze, tarsi speckled with pale yellow. Midlegs with femur bronze; tibia brown, distally pale yellow; tarsi bronze. Hindlegs with femur bronze; tibia brown, basally and distally pale yellow; tarsi bronze.
Male genitalia (N = 2) (Fig. 67 View Figures 64–69 ). Uncus broad, narrowing on distal half, apex truncate. Gnathos projection limited to small ridge. Valva ventral margin nearly straight, dorsal margin conspicuously convex, apex pointed. Juxta with broad rounded base, medially wide, apex broadly indented, weakly sclerotised. Saccus broad, quadrangular.
Female genitalia (N = 2) (Fig. 110 View Figures 107–110 ). Anterior apophyses without dorsal bump at posterior 1/3. Antrum sclerotisation ca. twice as long as broad. Ductus bursae short, straight, slender. Corpus bursae globular, reticulated, with sclerotisation between thorn and corpus opening, and faintly marked sclerotised band medially. Thorn long, incurved, with small dents pointing toward thorn base on inner side, glabrous on outer side.
Distribution.
Known from the Madang, the Northern and the Milne Bay Provinces (Papua New Guinea) at altitudes of ca. 1,600 m.
Remarks.
Nuss (1998) transferred this species from Eudorina to Hoploscopa . The handwritten label from Hampson stipulates that the type is a male, while the abdomen dissected shows it is a female. The abdomen was re-affixed to the specimen, suggesting that either the sex wasn’t identified properly by Hampson or that the wrong abdomen was reaffixed to the specimen.
