Diagnosis.
The forewing median markings form an interrupted pale yellow Y, and postmedian patch and subterminal line are pale yellow, well-marked. In male genitalia, the gnathos projection is ca. 2/3 of uncus length, spatula-shaped, broadening toward apex, and the cornutus displays a small but conspicuous bump. Female genitalia show a long ductus bursae broadly curved twice and a large pear-shaped corpus bursae.
Similar species.
Hoploscopa parvimacula sp. nov. (q.v.), H. brunnealis , H. danaoensis sp. nov., H. metacrossa . These species share similar forewing markings with H. kinabaluensis sp. nov. Male genitalia of these species show a gnathos projection larger at base, of constant width, reaching ca. half of uncus length, and a cornutus lacking the apical bump. In female genitalia, the shorter ductus bursae is nearly straight.
Description.
Head. Antennae dorsally striped with pale yellow and bronze scales. Proboscis brown speckled with pale yellow. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.
Thorax (Fig. 8 View Figures 4–18 ). Thorax dorsally pale yellow, laterally brown. Collar pale yellow. Forewing length: 9.0-10.5 mm (♂), 10-11 mm (♀); forewing ground colour brown; basal dark brown dash, distally pale yellow; median discoidal stigma and median cubital patch forming together a pale yellow-coloured Y, disrupted with brown at vein, edged basally and distally with dark brown; postmedian patch roughly triangular, pale yellow, invaded with brown, edged with dark brown; subterminal line thick, pale yellow; fringe chequered pale yellow and brown. Hindwing pale brown. Forelegs brown. Midlegs with femur brown; tibia brown, inwardly pale yellow; tarsi bronze. Hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi bronze, speckled with brown.
Abdomen. Male sternum A8 posterior margin broadly indented, with short, rounded lateral projections.
Male genitalia (N = 4) (Fig. 51 View Figures 46–51 ). Uncus broad, gently narrowing on distal half, apex obtuse. Gnathos projection ca. 2/3 of uncus length, narrow at base, widening toward apex, apex spatula-shaped. Valva ventral margin straight, gently bent dorsad on distal 1/3, dorsal margin convex, apex rounded or slightly pointed. Juxta slender, base roughly quadrangular, apex slightly incurved. Saccus small, pointing dorsad. Phallus with elongated cornutus, at posterior end with narrow bump pointing dorsad.
Female genitalia (N = 5) (Fig. 92 View Figures 91–94 ). Anterior apophyses with tip or bump at posterior 1/3. Antrum sclerotisation ca. twice as long as broad. Ductus bursae long, slender, with one loop, curved before corpus bursae. Corpus bursae conspicuously pear-shaped, reticulated, with sclerotisation between thorn and corpus opening and faintly marked sclerotised band medially. Thorn long, slightly curved, with small dents pointing toward thorn apex.
Distribution.
Known from the slopes of Mount Kinabalu and Mount Monkobo on Borneo, from altitudes between 975 m and 1,850 m.
DNA barcoding.
Two MOTUs diverging by 1.7-2.2% are recovered in H. kinabaluensis sp. nov. These two lineages are found in sympatry at Mount Kinabalu.
Etymology.
The species name kinabaluensis refers to Mount Kinabalu on Borneo, where the species occurs.
Remarks.
The two barcode lineages show no differences in wing pattern and female genitalia. Only minor differences are found in male genitalia, with the apex of the gnathos projection slightly narrower and the basal margin of the juxta slightly incurved in the second lineage. Since second MOTU is only represented by three specimens including only one male, further investigations with a greater number of specimens is needed.
