Diagnosis. The male genitalia structure of the new species is significantly different from allied species: valva with five diverse sized and formed processes, which are asymmetric in each valva; aedeagus vesica with a large spine˗shaped cornutus and scobination. In female genitalia, it can be distinguished from the latter by the asymmetri- cal ostial plate strongly sclerotized, with a large, strongly waved left spur (right one blunt).
Description. Adult ( Figs 6a, 6b View FIGURES 3–7 ). Length of forewing 5 mm in male, 6 mm in female. Head, patagium and tegula deep yellow. Thorax dark brown. Forewing ground color dark brown, with broad, deep yellow costal margin, which hind border broadly waved; with row of small, dark brown dots or patches from basal of costa to tornus; cilia deep yellow. Hindwing ground color light brown; cilia light brown. Abdomen brown, except deep yellow ventral side, with deep yellow anal tuft in male. Male genitalia ( Fig 12 View FIGURES 12–13 ). Uncus stout, tapering, with apex strongly angled, heavily covered with setae. Tegumen triangular, weakly sclerotized. Valva asymmetric, with four diverse sized and formed, strongly sclerotized processes; cucullus membranose (left one weakly sclerotized), club˗shaped. Saccus broadly “U”˗shaped. Aedeagus stout, weakly sclerotized and vesica with a large spine˗shaped cornutus and scobi- nation. Female genitalia ( Fig 18 View FIGURES 14–18 ). Papillae anales weakly covered with setae. Asymmetrical ostial plate strongly sclerotized: left plate with a large, strongly waved left spur, it is heavily covered with short spines and right plate blunt, covered with small spines partly. Ductus bursae tubular, membranous, weakly wrinkle, with sclerotized band. Corpus bursae irregularly ovoid, heavily covered with dense spinulose scobination in proximal half.
Distribution. Vietnam (Hanoi, Ninh Binh Prov.).
Etymology. The specific epithet is derived from the Latin “ quinque “ meaning “five” and “ cornutus ” meaning “horned”, refers to the five diverse sized processes of the valva in the male genitalia.
