Diagnosis.

Hoploscopa isarogensis sp. nov. is a relatively small brown-winged species (forewing length = 7-9.5 mm) with red markings edged yellow. Median discoidal stigma, cubital and dorsal patches form together a disrupted band, and postmedian patch is red with a pale yellow blotch at costa. In male genitalia, the apex of the uncus is duck beak-shaped, with a small marked bump on its ventral side, and gnathos projection is ca. 1/3 of uncus length, with an indented apex. In female genitalia, the corpus bursae displays a clearly delimited sclerotisation between the thorn and the corpus opening, and bears a long, thick, curved thorn.

Similar species.

Hoploscopa cynodonta sp. nov. (q.v.), H. ignitamaculae sp. nov. (q.v.), H. agtuuganonensis sp. nov. The forewings of H. agtuuganonensis sp. nov. display a trapezoid median discoidal stigma, and median markings are only slightly disrupted, while they are well separated in H. isarogensis sp. nov. In male genitalia, gnathos projection reaches 2/3 of uncus length and has a truncate apex. In female genitalia, ductus bursae is long, broad, with one loop, while it is shorter, slender and straight in H. isarogensis sp. nov., and the small corpus bursae displays one plump thorn with a small sclerotisation at its base.

Description.

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

Thorax (Fig. 17 ). Collar white. Forewing length: 7-8 mm (♂), 8-9.5 mm (♀); forewing ground colour brown; broad basal patch pale yellow to yellow, crossed by longitudinal reddish brown fascia running up to postmedian area; costal field reddish brown; median discoidal stigma rhomboid to elliptic, pale yellow, filled with reddish brown; cubital and dorsal pale yellow patches forming with median discoidal stigma an oblique band disrupted at veins; postmedian patch roughly triangular, reddish brown, more or less speckled with pale yellow, with pale yellow blotch at costa; subterminal line pale yellow, conspicuously incurved inwards at CuA2; subterminal field marked with reddish brown; fringe brown, with pale yellow dots. Hindwing pale brown. Forelegs brown. Midlegs brown, inner side pale yellow. Hindlegs brown, tibia marked with pale yellow.

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

Male genitalia (N = 2) (Fig. 60 ). Uncus long, medially broadened, narrowed at apical 1/4, apex duck beak-shaped, medio-ventrally with a small bump projecting ventrad. Gnathos projection ca. 1/3 of the uncus length, with apex notched. Valva ventral margin nearly straight, gently bent dorsad on distal 1/4, dorsal margin slightly convex, apex truncated. Juxta broad, with base rounded, medially slightly narrowed, apex slightly incurved. Saccus quadrangular.

Female genitalia (N = 6) (Fig. 100 ). Anterior apophyses with small dorsal bump at posterior 1/3. Antrum sclerotisation short, ca. as wide as long. Ductus bursae relatively short, nearly straight. Corpus bursae globular and reticulated but in some specimens with a rounded pouch-like extension, with well-marked sclerotisation between thorn and ductus bursae opening, medially with faintly sclerotised band. Thorn sabre-like, curved, with small dents pointing toward thorn base.

Distribution.

Known from the Luzon and Mindoro islands (Philippines), between sea level and 1,150 m.

DNA-barcoding.

Specimens from Luzon and Leyte show an K2P-distance of 3.4-3.9% and are recovered in two MOTUs.

Etymology.

Named after Mount Isarog (1966 m), a volcano on Luzon Island (Philippines) where the species is found.

Remarks.

Minor differences were observed in male and female genitalia of the specimens from Leyte. However, with only one male from Leyte on hand, we refrained from drawing further conclusions on its species status here.
