Diagnosis.

The antennae striped with white and the antemedian oblique white streak extended distally into white suffusion in the forewing are unique to this species. In male genitalia, the gnathos projection forms a broad plate with a small apical tip. In female genitalia, the antrum is membranous, the ductus bursae is long and corpus bursae is densely covered with erect papillae on one half.

Similar species.

No similar species known.

Description.

Head. Antennae dorsally striped with brown and white. Proboscis brown. Maxillary palpi brown, base pale brown, apex white. Labial palpi brown with white apex.

Thorax (Fig. 10 View Figures 4–18 ). Collar white. Forewing length: 8-9 mm (♂ & ♀); forewing ground colour brown; basal area of a darker brown; antemedian oblique thick white streak running from dorsum to upper margin of cell, distally extended into white suffusion; postmedian patch reduced to costal white blotch; postmedian line of a darker brown at costa; barely marked subterminal white line incurved inwards at CuA2, running up to M2; fringes pale brown. Hindwing pale brown. Fore- and midlegs brown, tibia and tarsi segments distally white. Hindlegs brown.

Male genitalia (N = 1) (Fig. 53 View Figures 52–57 ). Uncus medially conspicuously widened, narrowed at apical 1/4, apex spatulate. Gnathos projecting into a broad spatula-shaped plate with small apical tip on its middle. Valva ventral margin gently bent dorsad on distal 1/3, dorsal margin convex, apex pointed. Juxta slender, with base rounded, apex obtuse. Saccus small, pointing dorsad. Phallus with club-shaped cornutus.

Female genitalia (N = 1) (Fig. 94 View Figures 91–94 ). Anterior apophyses bent ventrad at 1/3. Antrum membranous. Ductus bursae long, straight. Corpus bursae globular, with one half reticulated, one half with erect papillae, with sclerotised bump on each side of thorn. Thorn straight, broad at base, tapering at mid-length, with small dents pointing toward thorn apex.

Distribution.

Known from the Papua (Indonesia) and Madang Provinces (Papua New Guinea) on New Guinea, at altitudes between 1,000 m and 1,700 m.

Phylogenetic relationships.

Hoploscopa niveofascia sp. nov. is recovered as sister group in the ML analysis of the COI barcode (BS = 95).

Remarks.
