Description. Adult (Fig. 3 f) with wingspan 17.0–21.0 mm. Head yellowish brown, white around compound eye. Antenna with scape snowy white on dorsal surface, brown on ventral surface; flagellum brown with snowy white. Labial palpus ocherous brown, second segment with appressed scales, white apically; third segment slender, longer than second segment. Thorax and tegula yellowish brown. Forewing with costal margin nearly straight, apex bluntly rounded, termen slightly concave near middle; ground color yellow, with scattered brown scales, black along apex and termen; markings blackish brown, edged with yellowish white: humeral patch rectangular; costal patch at basal 1/3, outwardly oblique; median patch irregularly shaped, large, extending from below costa to dorsum, its lower margin about 1/3 length of dorsum; discocellular stigma nearly key-like, its anterior half expanded, posterior half narrowed; subterminal patch trapezoidal, its outer margin extending from costal margin to dorsum; narrow black stripe extending from before lower angle of cell along CuA2 to dorsum at distal 1/5; subterminal fascia yellowish white, more or less obliquely straight, followed by a broad zone covered with dense grayish brown scales; fringe yellowish brown, gray distally, basal line yellowish white. Hindwing brown; fringe yellowish brown, basal line pale yellow. Fore and mid legs with ventral surface brown, yellowish brown on dorsal surface, tarsus white with brown; hind leg with femur brown, tibia dark brown, white at apex, tarsus white, mixed with blackish brown scales on dorsal surface.
Male genitalia (Fig. 6 a): Uncus broad at base, gradually narrowed to apex, slightly curved toward ventral surface. Gnathos broad at base, gradually narrowed to 3/5, distal 2/5 curved ventrad, conspicuously tapering to tip. Valva with basal 2/5 nearly trapezoidal, parallel sided medially; costa with basal 1/5 slightly oblique, concave medially; ventral margin almost straight; sacculus broad at base, narrowed to end, about 1/4 length of valva; cucullus covered with dense strong setae, triangular, straightly upturned, narrowed to blunt apex, outer margin slightly arched, ventro-distal corner blunt. Juxta nearly quadrate, straight on anterior margin, with a sharp-tipped triangular process on caudal margin; caudal lobe papillate, bearing long setae apically. Vinculum narrowed, slightly convex anteriorly. Aedeagus as long as valva, slightly S shaped, with four unequally sized denticles in distal 1/3 on ventral surface; cornuti being dense granules in distal half.
Female unknown.
Diagnosis. This species is superficially similar to D. cremnaspis (Meyrick, 1905). It can be distinguished by the valva with costa oblique basally and the juxta with one triangular process at middle on the caudal margin in the male genitalia. In D. cremnaspis, the costa of the valva is straight basally and the juxta has no process at middle on the caudal margin (Clarke, 1965: 39, Pl. 19, Fig. 2). This species is also similar to D. causidica (Meyrick) superficially. The differences between them are stated under D. causidica.
Distribution. China (Guizhou), Vietnam, Thailand.
Etymology. The specific name is derived from the Latin acut- (acute) and processus (process), referring to the sharply pointed triangular process of the juxta.
