Diagnosis.
Hoploscopa gracilis sp. nov. displays pale yellow crescent-shaped median discoidal stigma filled with reddish brown, together with median cubital patch forming a Y. In male genitalia, uncus is long and slender, valva is slender with pointed apex, and juxta displays a broad duck beak-shaped apex. In female genitalia, the ductus bursae is long, forming one loop on its middle, and the corpus bursae is small, globular, with one short slightly curved thorn.
Similar species.
Hoploscopa agtuuganonensis sp. nov., H. mallyi sp. nov. (q.v.). Median markings of the forewing form a band progressively narrowing toward dorsum in H. agtuuganonensis sp. nov. In male genitalia, uncus of H. agtuuganonensis sp. nov. is larger, valva has a rounded apex and juxta apex is tongue-shaped. Female genitalia of H. agtuuganonensis sp. nov. are very similar to those of H. gracilis sp. nov. but differ by a more marked corpus sclerotisation and a thicker thorn.
Description.
Head. Antennae dorsally ochreous to brown. Proboscis pale yellow. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.
Thorax (Fig. 38 View Figures 34–45 ). Collar pale yellow. Forewing length: 9 mm (♂), 11 mm (♀); forewing ground colour brown; broad elongated basal patch reddish brown with basal edge pale yellow, distally running up to median cubital patch; costal field reddish brown; median discoidal stigma crescent-shaped, pale yellow, filled with reddish brown; median cubital patch streak-like, pale yellow, disrupted at 1A+2A, together with median discoidal stigma forming a Y; postmedian triangular patch reddish brown, speckled with pale yellow, with pale yellow blotch at costa; postmedian area suffused with a mix of pale yellow and iridescent scales; subterminal field marked with reddish brown; fringes brown, with pale yellow dots. Hindwing pale yellow. Forelegs brown. Midlegs brown; tibia distally pale yellow. Hindlegs brown, tibia pale yellow speckled with brown.
Abdomen. Male sternum A8 posterior margin notched, with short, rounded lateral projections.
Male genitalia (N = 4) (Fig. 77 View Figures 76–81 ). Uncus long and slender, gently tapering toward apex, apex spatulate. Gnathos projection slender, ca. 2/3 of uncus length, with truncate apex. Valva slender, ventral margin nearly straight, gently bent dorsad on distal 1/4, dorsal margin convex, apex pointed. Juxta with base rounded, medially straight, widening at distal 1/3 onto duck beak-shaped apex. Saccus triangular, conspicuously pointing dorsad.
Female genitalia (N = 2) (Fig. 117 View Figures 115–118 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation as long as wide. Ductus bursae long, with one loop, curved before corpus opening. Corpus bursae small, globular, reticulated, with sclerotisation between thorn and corpus opening and faintly sclerotised band medially. Thorn small, plump, slightly curved, with small dents pointing toward thorn base, basally with small outwardly projected extension.
Distribution.
Known from North Sumatra, at altitudes between ca. 1,200 m to 1,900 m.
DNA barcoding.

Etymology.
From the Latin gracilis , slender, narrow, referring to the slender shape of the uncus, the gnathos projection, and the valva in male genitalia.
