Diagnosis. This new species can be differentiated from its allies by the viculum conspicuously constricted on anterior 1/ 3 in the male genitalia. It resembles D. paradichromella superficially, but differ in the male scape is 1.5 times as long as wide, the bell-shaped uncus, the finger-like postero-lateral lobe of the transtilla in the male genitalia, and the corpus bursae is double-kerneled peanut shaped in the female genitalia. In D. paradichromella , the male scape is 2.5 times as long as wide, the uncus is triangular, the postero-lateral lobe of the transtilla is right-angled triangle shaped, and the corpus bursae is elongate bag-shaped.
Description. Adult ( Fig. 13 View FIGURES 11–13 ) with wingspan 16.5̅22.0 mm. Head fuscous brown. Antenna brown, scape about 1.5 times as long as wide; male flagellum shallowly incurved basally, with a cluster of smaller scales. Labial palpus upturned just beyond vertex; first segment grayish white, second and third segments fuscous brown except whitetipped; second segment 1.7 times as long as third segment. Maxillary palpus brown. Patagium, tegula and thorax grayish brown. Forewing grayish brown, mottled with grayish white; antemedial line grayish white, from costal 1/3 from slightly oblique outward to dorsal 2/5, incurved at A, bordered outwardly by a black line and inwardly by an ovate, blackish brown patch near dorsum; discal spots blackish brown, fused, crescent; postmedial line grayish white, incurved at M 1 and CuA 2, edged outwardly with a grayish brown line and inwardly an indistinct broader band; terminal line black; cilia brown. Hindwing brown, cilia grayish brown. Foreleg blackish brown, mid and hindleg grayish brown mottled grayish white. Abdomen blackish brown, each segment darker in base than apex.
Male genitalia ( Fig. 24 View FIGURES 23–24 ). Uncus bell-shaped, about same length as width at proximal base. Gnathos about 5/8 length of uncus, tapered, apex slightly hooked. Transtilla produced in U shape posteriorly, postero-lateral lobe fingerlike, uniform in width, twice as long as width. Valva four times as long as wide, slightly narrower distally; clasper short and stout; costa clubbed, about 5/6 length of valva, apical 1/3 narrowed; sacculus 2/7 length of valva, sinuate in S shape, sharp at end. Juxta V-shaped; lateral lobe short, clubbed, as long as gnathos, three times as long as wide. Vinculum somewhat goblet-shaped, 1.4 times as long as maximum width, conspicuously constricted on anterior 1/3. Phallus stout, about same length as valva, with fascicle-shaped crimples.
Female genitalia ( Fig. 34 View FIGURES 32–34 ). Papillae anales large and wide, rounded at apex, with dense setae. Apophyses posteriores expanded at base, as long as apophyses anteriores. Eighth segment 1/3 as long as width. Antrum bowl-like, weakly sclerotized. Ductus bursae about half length of corpus bursae, smooth in posterior half, slightly broadened and granulated in anterior half. Corpus bursae twice as long as maximum width, double-kerneled peanut shaped, granulated near junction with ductus bursae; signum a rounded, invaginated cup consisting of concentrically arranged granules, situated at anterior 2/5 of corpus bursae. Ductus seminalis posterior margin of corpus bursae.
Distribution. China (Fujian, Guangxi, Hunan, Jiangxi).
Etymology. The specific name is derived from the Latin prefix strict-, meaning constricted, and the terminology vinculum, referring to the vinculum of this species is conspicuously constricted on anterior 1/3.
