Diagnosis.

Hoploscopa parvimacula sp. nov. displays brown forewings with reduced pale yellow markings. The median discoidal stigma is crescent-shaped, and the median cubital patch forms a streak not connected to the median discoidal stigma. The postmedian patch and postmedian area are faintly marked with pale yellow. In male genitalia, the gnathos projection is distally spatula-shaped, reaching ca. 2/3 of the uncus length, and the juxta displays blunt lateral projections and a truncate apex.

Similar species.

Hoploscopa kinabaluensis sp. nov., H. pangrangoensis sp. nov. The forewings of H. kinabaluensis sp. nov. display more contrasting postmedian patch and subterminal line, and a subterminal field suffused with pale yellow. In H. pangrangoensis sp. nov., the median cubital patch is almost absent and the subterminal line is more strongly pronounced. In male genitalia, base of gnathos projection is narrower and the cornutus displays a narrow bump at apex in H. kinabaluensis sp. nov. The finger-like gnathos projection of H. pangrangoensis sp. nov. is narrower than that of H. parvimacula sp. nov. and reaches only half the uncus length. In female genitalia, ductus bursae of H. kinabaluensis sp. nov. is twice as long as in other species, with a loop on its middle and a large bow before corpus bursae. In H. pangrangoensis sp. nov., colliculum is membranous with longitudinal sclerotised lines, corpus bursae is larger and thorn is smaller.

Description.

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

Thorax (Fig. 7 View Figures 4–18 ). Collar pale yellow. Forewing length: 9-10 mm (♂ & ♀); forewing ground colour brown; basal dark brown dash, distally pale yellow; basal and distal discoidal stigmata dark brown; median patches Y-shaped, pale yellow, disrupted with brown at vein, edged basally and distally with dark brown; postmedian patch of a lighter brown, with pale yellow triangular costal spot distally edged with dark brown; subterminal line pale yellow, distally dark brown; fringe brown, with pale yellow dots. Hindwing pale brown. Forelegs brown. Midlegs with femur brown; tibia pale yellow, speckled with brown; tarsi bronze. Hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi pale yellow to pale brown.

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

Male genitalia (N = 8) (Fig. 50 View Figures 46–51 ). Uncus medially broadened, narrowing on distal half, apex slightly obtuse. Gnathos projection ca. 2/3 of uncus length, spatula-shaped. Valva ventral margin straight, gently bent dorsad on distal 1/4, dorsal margin convex, apex rounded or slightly pointed. Juxta slender, base roughly quadrangular, apex truncate. Saccus small, pointing dorsad.

Female genitalia (N = 2) (Fig. 91 View Figures 91–94 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation twice as long as broad. Ductus bursae short and straight, slightly bent before corpus bursae. Corpus bursae pear-shaped, posterior half reticulated, anterior half membranous, with diffuse sclerotisation between thorn and corpus opening, medially with faintly marked sclerotised band. Thorn short and straight, with small dents pointing toward thorn apex.

Distribution.

Known from Mount Kinabalu on Borneo, at altitudes between 1,550 and 1,950 m.

DNA barcoding.

Sample MTD8229 of H. parvimacula sp. nov. shows a K2P-dist of 3.1-3.4% with samples from Borneo and is recovered as separate MOTU.

Etymology.

Refers to the Latin parvus, for small, and macula, for spot, referring to the Y-shaped median markings that are smaller than in other similar species.

Remarks.

The specimen with DNA voucher MTD8229 belongs to a series of females from the Malay Peninsula, which are morphologically similar to H. parvimacula sp. nov. and deposited at NHMUK. Since no males of the same series were available for investigations, we restrained from drawing further conclusions here.
