Diagnosis.

The white-coloured basal patch and median discoidal stigma as well as the oblique postmedian line allows separation of H. quadripuncta from its congeneric species. In male genitalia, uncus apex is cuneate and gnathos projection is ogive-shaped. In female genitalia, the thorn of the corpus bursae is long, slender, curved, and shows a well-marked rounded sclerotisation at its base.

Similar species.

No similar species known.

Description.

Head. Antennae dorsally bronze. Proboscis white. Maxillary palpi brown, base and inner side pale brown. Labial palpi brown, ventral base and inner side white.

Thorax (Fig. 23 ). Collar pale yellow. Forewing length: 8.5-10 mm (♂), 10 mm (♀); forewing ground colour brown; basal quadrangular oblique white patch, basally and distally edged with dark brown, with tawny to reddish brown fascia along CuA2 spreading distally into postmedian area up to costa; median white rounded patch edged with dark brown; postmedian line oblique, straight, thick; fringes brown. Hindwing pale brown. Forelegs brown. Midlegs with femur brown, tibia and tarsi pale yellow. Hindlegs pale brown.

Abdomen. Male sternum A8 posterior margin notched.

Male genitalia (N = 3) (Fig. 63 ). Uncus long and slender, narrowed at apical 1/4, apex cuneate. Gnathos projection ogival, ca. 1/3 of uncus length. Valva slender, ventral margin straight on basal 2/3, bent dorsad on apical 1/3, dorsal margin convex, apex pointed. Juxta with base rounded, medially narrowed, apex broad, weakly sclerotised. Saccus broad, triangular, pointing dorsad. Phallus with flat spatula-shaped cornutus, apically with narrow bump.

Female genitalia (Fig. 105 ). Anterior apophyses with tip pointing upward at posterior 1/3. Antrum with a narrow weakly sclerotised ring. Ductus bursae of medium length, straight. Corpus bursae ovoid, posterior half reticulated, anterior half membranous, sclerotised between thorn and corpus opening, medially with faintly sclerotised band. Thorn long, curved, with small dents pointing toward thorn base on posterior edge, basally with conspicuous outwardly directed plump extension.

Distribution.

Recorded from the Oetakwa River (Papua: Indonesia) in New Guinea, also known from the Oro Province (Papua New Guinea) and the Moluccas (Indonesia), at altitudes between 500 m and 1,000 m.

Remarks.

Nuss (1998) transferred this species from Eudorina to Hoploscopa . Other specimens examined from the Moluccas and Papua New Guinea display the same pattern as the holotype from Western New Guinea, however a small difference in the shape of the gnathos projection is observed: it is pointed in the holotype, while it is rounded in the other specimens. Unfortunately, no molecular investigations were done on the holotype.
