Diagnosis. This new species can be separated from its congeners by the forewing black from the base to the inner margin of the antemedial line. The genitalia structures are similar to those of D. dichromella , differing in the male genitalia by the triangular uncus gradually narrowed to apex, the clubbed gnathos tapered to a hooked apex; and in the female genitalia by the subtriangular corpus bursae twice as long as the maximum width and the signum situated in the middle of the corpus bursae. In D. dichromella , the uncus is subtriangular in the basal half, sharply narrowed at middle and tubular in the distal half, the gnathos is broadened in distal half and the apex is not hooked in the male genitalia; the elongate bag-shaped corpus bursae is 3.5 times as long as its maximum width, and the signum is situated at the anterior 2/7 of the corpus bursae in the female genitalia.

Description. Adult ( Fig. 4 ) with wingspan 21.5̅ 27.5 mm. Head grayish brown. Antenna grayish white, scape about twice as long as wide, male with basal several flagellomeres constricted, incurved, without scale tufts; female flagellum simple. Labial palpus upturned beyond vertex; first segment grayish brown mixed with grayish white; second and third segments about equal length, grayish brown to blackish brown. Maxillary palpus grayish brown mixed with grayish white. Patagium, tegula and thorax yellowish brown to brownish fuscous. Forewing black in basal area, from grayish white gradually to grayish brown in medial area, grayish brown in distal area; antemedial line white, from costal 1/3 obliquely outward to dorsal 2/7; discal spots indistinct, black, fused into a club shape; postmedial line grayish white, sinuate, incurved at M 1 and CuA 2; terminal line black; cilia grayish brown. Hindwing pale grayish brown; cilia brown basally, pale brown distally. Foreleg blackish brown with scattered white scales, midleg grayish brown mixed with white, hindleg grayish white; tarsi black except white at apex of each tarsomere. Abdomen with dorsal surface blackish brown except yellow at posterior margin of each segment, ventral surface yellowish brown.

Male genitalia ( Fig. 15 ). Uncus triangular, longer than width at proximal base, gradually narrowed to rounded apex. Gnathos about 2/3 length of uncus, clubbed, tapered to hooked and slightly bifurcate apex, apico-dorsal portion minutely serrated. Transtilla produced in V shape posteriorly; postero-lateral lobe three times length of its medial width, tapered from base to narrowly rounded apex, forming an acute angle of about 45°. Valva three times as long as wide, narrowed at base, gradually broadened to middle, then narrowed to rounded apex; clasper an indistinct mastoid process at basal 1/7, bearing short setae; costa about 5/6 length of valva; sacculus sinuate, clubbed, 2/7 length of valva. Vinculum U-shaped posteriorly, 1.3 times as long as wide, concave on lateral margins at anterior 1/3, rounded anteriorly. Juxta broad V-shaped; lateral lobes about 4/5 length of gnathos, clubbed, slightly widened to rounded apex, bearing sparse setae. Phallus slightly longer than valva, with sclerotized crimples, crimples granulate in distal half.

Female genitalia ( Fig. 26 ). Papillae anales large and wide, with sparse setae, rounded at apex. Apophyses anteriores slightly longer and stouter than apophyses posteriores. Eighth segment about 2.5 times as wide as long. Antrum a narrow transverse band. Ductus bursae short, about 1/4 length of corpus bursae, gradually broadened, posterior 2/5 smooth, anterior 3/5 granulate on inner wall. Corpus bursae not easily differentiated from ductus bursae, subtriangular, twice as long as maximum width, granulate on inner wall in posterior 1/5; signum a rounded, invaginated cup consisting of concentrically arranged granules, situated at middle of corpus bursae. Ductus seminalis originating from posterior 1/5 of corpus bursae.

Distribution. China (Anhui, Beijing, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangxi, Liaoning, Shaanxi, Shandong, Sichuan, Tianjin, Zhejiang).

Etymology. The specific name is derived from the Latin prefix basi -, meaning basal, and the Latin word niger, meaning black, referring to the forewing black in the basal area.
