Material examined.

Holotype: ♀, with labels: "Indonesia, Java, M[oun]t. Pangrange | 30 km S[outh]E[ast] Bogor, 1625 m | primary forest 16-20.ii.1996 | 6.30S 107.10E leg. Siniaev & Afonin"; "Lepidoptera | date: i.2018 | MTD 7433 | [vertically written:] DNA-voucher"; "TL | 636 ♀". Deposited in MFNB.

Paratypes: 4 ♂, 1 ♀. Indonesia: 2 ♂ (1 with genitalia on slide TL659 ♂), 1 ♀ (DNA voucher MTD7431, genitalia on slide TL627 ♀), same data as holotype; 2 ♂ (1 with genitalia on slide TL660 ♂), same data as holotype except 21-26.ii.1996 (MFNB).

Diagnosis.

The forewing markings of H. pangrangoensis sp. nov. are reduced to a small crescent-shaped median discoidal stigma; median cubital and dorsal patches are not marked, and postmedian patch is reduced to a blotch at costa. In male genitalia, the uncus is medially widened and the gnathos shows a finger-like projection ca. half the length of uncus. In female genitalia, the thin longitudinal sclerotised lines of the antrum are unique to this species.

Similar species.

Hoploscopa parvimacula sp. nov. (q.v.), H. sumatrensis sp. nov. Hoploscopa sumatrensis sp. nov. shares with H. pangrangoensis sp. nov. the crescent-shaped pale yellow median discoidal stigma on the forewing and the small median cubital patch. However, median discoidal stigma and postmedian patch are filled with reddish brown in H. sumatrensis sp. nov. In male genitalia, the gnathos projection reaches 4/5 of the uncus length in H. sumatrensis sp. nov. In female genitalia, antrum of H. sumatrensis sp. nov. is completely sclerotised.

Description.

Head. Antennae dorsally striped with brown and bronze scales. Proboscis pale brown. Maxillary palpi brown, ventro-basally pale yellow. Labial palpi brown, base and inner side pale yellow.

Thorax (Fig. 16 ). Collar pale yellow. Forewing length: 10-11 mm (♂ & ♀); forewing ground colour brown; basal dark brown dash distally pale yellow; small pale yellow spot at base of cell; basal and distal discoidal patches dark brown; median discoidal stigma crescent-shaped, white to pale yellow; median cubital pale yellow blotch in some specimens; postmedian pale yellow streak at costa, distally with dark brown streak; postmedian area speckled with pale yellow; subterminal line pale yellow, diffuse; fringes brown, with pale yellow dots. Hindwing pale brown. Forelegs brown, tarsi pale brown. Midlegs with femur brown; tibia brown speckled with pale yellow; tarsi pale yellow speckled with bronze. Hindlegs with femur brown; tibia pale yellow, speckled with pale brown; tarsi pale yellow.

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

Male genitalia (N = 2) (Fig. 59 ). Uncus medially widened, narrowed on apical 1/4, apex blunt. Gnathos projection finger-shaped, ca. half the length of uncus. Valva ventral margin straight, gently bent dorsad on distal 1/3, dorsal margin conspicuously convex; apex slightly pointed. Juxta with base quadrangular, medially narrowing, apex roughly rounded, slightly notched. Saccus triangular, conspicuously pointing dorsad.

Female genitalia (N = 2) (Fig. 97 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum elongated, membranous, with thin longitudinal sclerotised lines, anteriorly with minute sclerotised markings. Ductus bursae short, bent before corpus opening. Corpus bursae pear-shaped, reticulated, with sclerotisation between thorn and corpus opening and faintly marked sclerotised band medially. Thorn small, straight, with small dents pointing toward thorn apex.

Distribution.

Known from the slopes of Mount Pangrango (3019 m) on Java (Indonesia), at an altitude of 1,625 m.

Etymology.

Named after Mount Pangrango, a dormant stratovolcano on Java, where the specimens were collected.
