Diagnosis. The male genitalia structure of the new species is similar with Diduga quinquicornuta ( Bayarsaikhan & Bae, 2019: fig. 12; present paper: fig. 14c), but can be distinguished from the latter by the more stout, long (towards apex of uncus) basal saccular process of left valva with rounded apex; apex of right valva strongly bifurcated, which lower and upper angle’s processes irregularly truncate, dentate margin. In D. quinquicornuta , slender, short (towards apex of tegumen) basal saccular process of left valva with angled apex; apex of right valva strongly four branched, which processes variously spine˗shaped ( Fig 14c View FIGURE 14 ).
Description. Adult (Figs 4a, 4b). Length of forewing 7 mm in both sexes. 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 pale brown; cilia pale brown. Abdomen brown, except deep yellow ventral, with deep yellow anal tuft in male. Male genitalia ( Fig 14a View FIGURE 14 ). Uncus stout, tapering, with apex strongly angled, heavily covered with setae. Tegumen triangular, weakly sclerotized. Valvae asymmetric: in left valva, short (almost same length with tegumen), irregularly triangular, with waved four diverse sized (among them one bifurcated), strongly sclerotized processes; cucullus membranose, club˗shaped, with costal sclerotized area; long (towards apex of uncus) basal saccular process of left valva with rounded, dentate apex; in right valva, square, almost same sized with left valva, with rectangular upper one and irregularly triangular lower one processes strongly sclerotized, dentate margin; cucullus membranose, club˗shaped. Juxta triangular. Saccus broadly “U”˗shaped. Aedeagus stout, weakly sclerotized and vesica with a large spine˗shaped cornutus and scobination. Female genitalia ( Fig 14b View FIGURE 14 ). Papillae anales weakly covered with setae. Asymmetrical ostial plate strongly sclerotized: left plate with strongly waved left and irregularly arch˗shaped right plates, both side covered with small spines wholly. Ductus bursae tubular, membranous, with strongly sclerotized band. Corpus bursae ovoid, heavily covered with dense spinulose scobination.
Distribution. China (Hainan).
Etymology. The species is named for the type locality, Hainan Prov., China.
