Diagnosis.

Hoploscopa albomaculata sp. nov. is unique by virtue of its median trapezoid and postmedian streak-like white patches on the forewing. In male genitalia, the gnathos projection is reduced to a small triangular tip, and the juxta is elongated, slender, with a deeply indented apex. In female genitalia, ductus bursae is long, broad and curvy, and corpus bursae displays well-delimited sclerotised band and a straight thorn.

Description.

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

Thorax (Fig. 35 ). Collar pale yellow. Forewing length: 9 mm (♂), 9-10 mm (♀); forewing ground colour brown; small basal white dash edged with dark brown; median discoidal stigma trapezoid, white, with basal and distal edges dark brown; postmedian patch streak-like, white, pale yellow at costa, edges dark brown; subterminal line dark brown, basally faintly marked with pale yellow; fringes basally pale yellow, distally brown. Hindwing pale brown. Forelegs bronze. Mid- and hindlegs with femur brown; tibia pale yellow speckled with brown; tarsi bronze.

Abdomen. Male sternum A8 posterior margin bilobed, laterally with short, rounded lateral projections.

Male genitalia (N = 5) (Fig. 74 ). Uncus medially slightly widened, narrowed at apical 1/4, apex roughly truncate, ventrally with a triangular tip pointing posterad. Gnathos projection short, wide at base, triangular. Valva ventral margin nearly straight, dorsal margin conspicuously convex, apex pointed. Juxta slender, with base rounded, narrowing toward apex, apex deeply indented. Saccus small, pointing dorsad.

Female genitalia (N = 3) (Fig. 114 ). Anterior apophyses without dorsal bump at posterior 1/3. Ductus bursae long, slender, gently curved twice. Antrum sclerotisation short, as long as wide. Corpus bursae small, globular, reticulated, with marked elongated sclerotisation from corpus opening to thorn. Thorn straight, with small dents pointing toward thorn apex.

Distribution.

Known from North Sulawesi (Indonesia) at altitudes between 1,000 m and 1,200 m.
