Rimandai, S. Sau, A. Kinibel, M. Jimbudo (USNM). Diagnosis. The well-marked median cubital and dorsal snow-white patches on the forewing segregate this species from its congeners. Median discoidal stigma is trapezoid, reddish brown, postmedian patch is reddish brown, distally edged by thin white streak. In male genitalia, the narrow uncus-tegumen connection and the broadly indented uncus apex is unique to this species. In female genitalia, papillae anales are thick, not connecting dorsally and ventrally, corpus bursae is small, globular, with a long straight thorn. Similar species. No similar species known. Description. Head . Antennae dorsally brown. Proboscis pale brown. Maxillary palpi dark brown, base and inner side pale yellow to light brown. Labial palpi dark brown, ventro-basally pale yellow. Thorax (Fig. 12 ). Collar white. Forewing length 10-11 mm (♂), 9-10 mm (♀); forewing ground colour dark brown; cubital reddish brown fascia running from basal to postmedian area; basal and distal discoidal patches of a darker brown; rhombical reddish brown median discoidal stigma therebetween, basally and distally thinly edged with pale yellow; median cubital and dorsal patches white, elongated, slightly disrupted at 1A+2A; postmedian roughly quadrangular reddish brown patch, crossed with brown lines, with slender white streak abutting dorsally, running up to costa; postmedian line thin, marked on costal half; postmedian fascia white, speckled with brown; subterminal line thin, white, running more or less straight from dorsum distal 1/4 to apex; subterminal field faintly marked with reddish brown; fringes brown, with pale yellow dots. Hindwing pale yellow, slightly darker at apex. Legs brown, tibia distally pale yellow, tarsi brown to pale brown. Abdomen . Male sternum A8 posterior margin bilobed. Male genitalia ( N = 1) (Fig. 54 ). Uncus slender, entirely sclerotised, forming narrow connection to tegumen, narrowed on its middle, apex large, broadly indented. Gnathos reduced to barely sclerotised band. Tegumen arms dorso-posteriorly not fused. Valva slender, ventral margin nearly straight, gently bent dorsad on distal 1/4, dorsal margin convex, valva apex pointed. Juxta with base rounded, medially slightly narrowed with weakly sclerotised edges, apex broadly rounded, flanked on each side with sclerotised bump covered with setae. Saccus not pronounced. Phallus apically with sclerotised spine. Female genitalia ( N = 2) (Fig. 96 ). Papillae anales thick, dorsally and ventrally not connected. Posterior apophyses bent dorsad. Anterior apophyses widened at posterior 1/3, with tip pointed dorsad. Antrum sclerotisation as long as broad. Ductus bursae long, more or less straight. Corpus bursae small, globular, reticulated, with sclerotisation between thorn and corpus opening. Thorn straight, with small dents pointing toward thorn base, basally with small outwardly projected extension. Distribution. Known from Yawan village (1,700 m) in the Eastern Highlands Province (Papua New Guinea). Biology. The moths were reared from the fern Diplazium esculentum (Retzius in Retzius & Koenig , 1791) Swartz, 1803 ( Athyriaceae ) (S. Miller, C. Redmond & T. Whitfield, pers. comm.). Etymology. The species epithet gombongi comes from "gombong" , the name for fern in the Yau language (https://www.ethnologue.com/language/yuw), referring to the larval host plant. This name was suggested by Vojtech Novotny and Gibson Mayiah.
