Diagnosis. The male and female genitalia structure of the new species is similar with Diduga dubatolovi (Bayarsaikhan & Bae, 2018: fig. 9, 20; present paper: fig. 10c,d), but can be distinguished from the latter by the shorter processes of upper and lower angles of valvae, in left valva, short (almost two times shorter than D. dubatolovi), slightly waved lower angle’s process with stout apical spine; strongly waved, broadly oval˗shaped upper angle’s process with finger˗shaped dorsal projection; in right valva, stout lower angle’s process with a straight, long, slender apical spine; upper angle’s process two times broader than lower one, with finger˗shaped dorsal projection; aedeagus waved, with a long, slender, waved, spine˗shaped cornutus and scobinated plate in male genitalia; ostial plate of female genitalia weakly sclerotized, without any spines; ductus bursae broad, almost straight, tube˗shaped; corpus bursae with strongly sclerotized spines in cervix of bursae and scobinated in apical half, while in D. dubatolovi; in left valva, long, strongly angled lower angle’s process with slender apical spine (almost half size of D. allodubatolovi n. sp.); upper angle’s process slender, waved (almost two times longer than D. allodubatolovi n. sp.); in right valva, more stout lower angle’s process with a waved apical spine; weakly waved, finger˗shaped upper angle’s process with “X”˗shape apical spurs; aedeagus waved just apical half, with an almost straight and short (three times shorter than D. allodubatolovi n. sp.) spine˗shaped cornutus and scobinated plate (Fig 10c) in male genitalia; ostial plate of female genitalia strongly sclerotized, with two spines; ductus bursae narrow, waved, tube˗shaped, with a strongly sclerotized, aloe leaf˗shaped plate in cervix of bursae; corpus bursae without spines and scobinated (Fig 10d).
Description. Adult (Figs 2a, 2b). Length of forewing 5˗6 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; terminal fascia dark brown; 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 10a). Uncus slender, waved, with a small apical spine. Tegumen irregularly triangular, weakly sclerotized. Valvae asymmetric, stout: short, slightly waved lower angle’s process of left valva with stout apical spine; strongly waved, broadly oval˗shaped upper angle’s process with finger˗shaped (half size of uncus) dorsal projection; in right valva, stout lower angle’s process with a straight, long (almost same length with uncus), slender apical spine; upper angle’s process two times broader than lower one, with finger˗shaped (0.5 times shorter than left valva’s process) dorsal projection; aedeagus waved, with a long, slender, waved, spine˗shaped cornutus and scobinated plate. Female genitalia (Fig 10b). Papillae anales weakly covered with setae. Ostial plate weakly sclerotized. Ductus bursae broad, almost straight, tube˗shaped, weakly sclerotized whole of length. Corpus bursae with strongly sclerotized spines near cervix of bursae and scobinated in apical half.
Distribution. China (Hainan, Yunnan).
Etymology. The species is named allodubatolovi (near D. dubatolovi) referring to the superficial characteristics with those of genitalia.
