Diagnosis. This new species can be distinguished from its congeners by the male flagellum having a deep notch at base containing a cluster of smaller scales that are arranged in helix shape. The male genitalia resemble those of D. paradichromella , but differ in the transtilla being ovate at connection and the lateral lobes of the juxta truncate at apex. In D. paradichromella , the transtilla is band-like at connection, and the juxta lateral lobe is rounded.

Description. Adult ( Fig. 3 ) with wingspan 17.5̅27.0 mm. Head yellowish white to golden yellow. Antenna brown to blackish brown, male scape about 2.5 times as long as wide, basal several flagellomeres incurved, forming a deep notch containing a cluster of smaller scales arranged in helix shape; female scape shorter, flagellum simple. Labial palpus upturned just beyond vertex, grayish brown to blackish brown; third segment slightly shorter than second segment. Maxillary palpus blackish brown. Patagium, tegula and thorax grayish brown to blackish brown. Forewing grayish brown to blackish brown, individual scales grayish white-tipped; antemedial line ill-defined, grayish white, from costal 1/4 sinuate to dorsal 2/5, incurved at CuP, bordered by ill-defined sub-triangular black patch on its outer margin near costa and on its inner margin near dorsum; discal spots black, separated; postmedial line grayish white, sinuate, incurved at M 1 and near CuA 2, edged with black; terminal line black; cilia grayish brown to blackish brown. Hindwing pale grayish brown to fuscous brown; cilia brown. Legs grayish brown to blackish brown, midleg and hindleg grayish white at apex of each tarsomere. Abdomen yellowish brown to blackish brown, edged with grayish yellow on posterior margin of each segment, sometimes light-colored on ventral surface.

Male genitalia ( Fig. 14 ). Uncus triangular, longer than width at proximal base, rounded at apex. Gnathos clubbed, about half length of uncus. 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 2.5 times as long as wide, gradually broadened toward rounded apex; clasper an indistinct mastoid process at basal 1/5, bearing short setae; costa about 4/5 length of valva, slightly narrowed distally; sacculus 2/7 length of valva, basal 1/3 subtriangular, smooth, distal 2/3 spatulate, with long setae. Juxta V-shaped, lateral lobes slightly shorter than gnathos, digitate, truncate at apex, bearing sparse setae in distal half. Vinculum U-shaped, length same as maximum width. Phallus about 1.2̅1.4 times length of valva, with sclerotized crimples and a bundle of spines in distal half.

Female genitalia ( Fig. 25 ). Papillae anales large and wide, with sparse setae, rounded at apex. Apophyses posteriores and anteriores short, about equal length. Eighth segment broad and short. Antrum lip-shaped. Ductus bursae membranous, uniform in width, about 1.5 times length of corpus bursae, granulate on inner wall except near antrum. Corpus bursae ovate, 1.5 times as long as wide, granulated in posterior half; signum a rounded, invaginated cup consisting of concentrically arranged granules, situated at posterior 1/3 of corpus bursae. Ductus seminalis originating from posterior 2/5 of corpus bursae.

Distribution. China (Gansu, Guizhou, Henan, Hubei, Shaanxi, Sichuan).

Etymology. The specific name is derived from the Latin prefix antenn -, meaning antenna, and the Latin word alveatus, meaning notched, referring to the deep notch at base of flagellum in male.
