Diagnosis.

The forewings of H. sumatrensis sp. nov. display a pale yellow crescent-shaped median discoidal stigma filled with reddish brown, as well as a postmedian area broadly suffused with pale yellow. In male genitalia, the gnathos projection is slender, ca. 4/5 of uncus length, with a tongue-shaped apex, and the juxta has a rounded base and a notched apex. In female genitalia, the short and slender ductus bursae bent before corpus and the pear-shaped corpus bursae with small straight thorn resemble those of other Hoploscopa species, e.g., H. danaoensis sp. nov. and H. parvimacula sp. nov.

Description.

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

Thorax (Fig. 36 View Figures 34–45 ). Collar pale yellow. Forewing length: 9-10 mm (♂ & ♀); forewing ground colour brown; small basal dark brown dash distally pale yellow; base of dorsum with patch of pale yellow scales; cubital reddish brown fascia running up to median area; median discoidal stigma reddish brown, edged with crescent-shaped pale yellow patch; postmedian patch reddish brown, with pale yellow blotch at costa; subterminal line broad, pale yellow; subterminal field tawny to brown; fringes brown, with pale yellow dots. Hindwing pale yellow. Forelegs bronze. Midlegs with femur brown; tibia pale yellow to brown; tarsi bronze. Hindlegs brown; tibia pale yellow speckled with brown; tarsi bronze.

Abdomen (Fig. 83 View Figures 82–86 ). Male sternum A8 posterior margin bilobed.

Male genitalia (N = 4) (Fig. 75 View Figures 70–75 ). Uncus medially broad, narrowed at apical 1/4, apex tongue-shaped. Gnathos projection slender, ca. 4/5 of uncus length, apex tongue-shaped. Valva ventral margin straight, bent dorsad on distal 1/4, dorsal margin convex, apex pointed. Juxta base rounded, distal half narrowed, apex notched. Saccus triangular, pointed.

Female genitalia (N = 4) (Fig. 115 View Figures 115–118 ). Anterior apophyses with dorsal tip at posterior 1/3. Antrum sclerotisation short. Ductus bursae short, bent before corpus opening. Corpus bursae large, pear-shaped, with sclerotisation between thorn and corpus opening and a median sclerotised band. Thorn small, straight, with small dents.

Distribution.

Known from North Sumatra (Indonesia).

DNA barcoding.

Two MOTUs are found in morphologically identical specimens from the same locality. The K2P-distance between the two MOTUs is 4.1-6%. The first MOTU, which is the one of the type material, shows an intraspecific variation of 0.7%. The second MOTU is found in three females (samples BC MTD LEP01422, MTD8258 and MTD8261) and shows an intraspecific divergence of 0.6%.

Etymology.

Named after the island of Sumatra where the species is encountered.

Remarks.

Future examination of male specimens from the second lineage will help to determine whether or not it represents a separate species.
