(Figs. 2 b, 4a)
Type material. Holotype ♂, China: Guizhou Province: Dashahe, Daozhen County, 1350 m, 26.VIII.2004, coll. Yunli Xiao, genitalia slide No. ZYM06346. Paratype: 1♂, Guocun, 1300 m, same data as holotype except dated 20.VIII.2004. Types deposited in NKUM.
Description. Adult (Fig. 2 b) with wingspan 13.5–14.0 mm. Head grayish brown, white around compound eye. Antenna pale yellow. Labial palpus brown except second segment white apically. Thorax and tegula grayish brown. Forewing with costal margin almost straight, apex triangularly produced, termen slightly concave below apex; ground color yellowish brown, with scattered brown scales; markings dark brown, edged with pale yellow: humeral patch a small spot; costal patch at basal 2/5, wedge-shaped; median patch elliptical, extending from upper margin of cell to dorsum; discocellular stigmata two, rounded, located one above another; subterminal patch trapezoidal, its outer margin extending from costal margin to dorsum; subterminal fascia pale yellow, slightly arched outwardly at middle; fringe pale gray. Hindwing grayish brown; fringe gray. Legs yellowish white.
Male genitalia (Fig. 4 a): Uncus broad at base, slightly narrowed to about 2/5, then gradually narrowed to pointed apex. Gnathos with basal 4/5 broad, nearly trapezoidal, distal 1/5 triangular, curved downward, pointed. Valva broad at base, narrowed to middle; costa deeply concave medially; ventro-distal corner blunt; sacculus short, about 1/4 length of valva; cucullus triangular, upturned, apex narrowly rounded, outer margin slightly arched. Juxta shield-like, protruded antero-medially; caudal margin straight, posterior half with an upright, narrow leaf-shaped process longitudinally; caudal lobe elongate, curved inward, pointed distally, about 2/3 length of juxta. Vinculum narrowly banded. Aedeagus slightly shorter than valva, curved medially, produced to a slender free process ventroapically; cornuti consisting of scattered granules in distal half, a row of small denticles connected with an arrowhead-shaped process exceeding apex of aedeagus.
Female unknown.
Diagnosis. This species is superficially similar to D. ovatella Park & Heppner, 2001. It can be distinguished by the valva with the costa deeply concave medially, the juxta with a narrow, upright, narrow leaf-shaped process longitudinally on posterior half, and the aedeagus with an arrowhead-shaped cornutus in the male genitalia. In D. ovatella, the costa of the valva is shallowly concave, the juxta has a upright, semicircular process on posterior 2/3, and the cornuti consist of spinuous plates located medially and apically (Park & Heppner, 2001: 47, Fig. 7).
Distribution. China (Guizhou).
Etymology. The specific name is derived from the Latin angusti- (narrow) and foliaceus (leaf-shaped), referring to the narrow leaf-shaped process of the juxta.
