Diagnosis.
The forewings of H. metacrossa display Y-shaped median and a postmedian pale yellow patches observed in several other Hoploscopa species (e.g., H. danaoensis sp. nov.). Male hindwing displays an androconial organ on the dorsum. The strongly sclerotised tympanic drum in tympanal organs of males is only observed in this species. In male genitalia, gnathos is projected into a small, slender, tongue-shaped tip, and valva is broad, with a rounded ventral margin. In female genitalia, antrum sclerotisation is as long as wide, ductus bursae is short, straight and the corpus bursae is large.
Similar species.
Hoploscopa brunnealis , H. danaoensis sp. nov., H. kinabaluensis sp. nov. (q.v.), H. pseudometacrossa sp. nov. (q.v.). Males of H. metacrossa are easily separated from similar species (except H. pseudometacrossa sp. nov.) by the presence of scent organs on the hindwing, the sclerotised tympanic drum, and the characteristic spatulate uncus apex with ventral ridges. Female genitalia of the four above-mentioned species are similar, but ductus bursae is bent before corpus bursae in these species (nearly straight in H. metacrossa ) and corpus bursae are smaller than that of H. metacrossa .
Description.
Head. Antennae dorsally brown. Proboscis pale yellow to brown. Maxillary palpi brown, base and inner side pale yellow. Labial palpi brown, ventral base and inner side pale yellow.
Thorax (Fig. 42 View Figures 34–45 , 45 View Figures 34–45 ). Collar pale yellow. Forewing length: 9-10 mm (♂ & ♀); forewing ground colour brown; basal dark brown spot distally pale yellow; median discoidal stigma trapezoid, pale yellow, together with cubital pale yellow patches forming a Y; postmedian patch pale yellow speckled with brown, distal edge dark brown; postmedian line marked on costal half; postmedian area variously suffused with pale yellow; subterminal line pale yellow; fringes brown with pale yellow dots. Hindwing pale brown; in males, presence of an androconial organ on the dorsum of the hindwing. Forelegs brown. Mid- and hindlegs with femur brown; tibia pale yellow, speckled with brown; tarsi brown.
Abdomen (Fig. 84 View Figures 82–86 , 86 View Figures 82–86 ). Male sternum A8 posterior margin broadly indented, with short, rounded lateral projections.
Male genitalia (N = 3) (Fig. 81 View Figures 76–81 ). Uncus slender, narrowed at apical 1/4, apex spatulate, bearing thick setae, ventrally with five small ridges. Gnathos projection ca. 1/4 of uncus length, slender, tongue-shaped. Valva ventral margin curved dorsad on distal half, dorsal margin conspicuously convex, apex rounded. Juxta with base rounded or slightly quadrangular, narrowing at basal 1/4, apex tongue-shaped. Saccus triangular, conspicuously pointing dorsad. Phallus with elongated, flat, spatula-shaped cornutus with subapical tip.
Female genitalia (N = 3) (Fig. 121 View Figures 119–122 ). Anterior apophyses with dorsal bump at posterior 1/3. Antrum sclerotisation short, as long as wide. Ductus bursae short, nearly straight. Corpus bursae spherical, reticulated, with sclerotisation between thorn and corpus opening and faintly marked sclerotisation medially. Thorn straight, with small dents pointing toward thorn base, basally with small outwardly projected extension.
Distribution.
Known from the Papua (Indonesia) and the Morobe Provinces (Papua New Guinea) in New Guinea, at altitudes between 600 and 1,200 m.
