(Figs. 3 e, 5f)
Type material. Holotype ♂, Thailand: Chiang Mai, Doui Pakia, 1500 m, 1–4.IX.1987, coll. S. Moriuti, T. Saito, Y. Arita & Y. Yoshiyasu, genitalia slide No. CIS-6218/Park. Paratype: Thailand: 1♂, Chiang Mai, Doui Pui, 1300 m, 5–7.IX.1987, coll. S. Moriuti, T. Saito, Y. Arita & Y. Yoshiyasu. The holotype is deposited in OPUJ and the paratype in KNA.
Description. Adult (Fig. 3 e) with wingspan 13.0 mm. Head grayish brown. Antenna yellowish brown, grayish white on ventral surface. Labial palpus ochreous brown; second segment grayish white on inner surface, with appressed scales; third segment slender, longer than second segment. Thorax and tegula brown. Forewing with costal margin slightly arched, apex produced triangularly, termen slightly concave medially; ground color brown, distal 1/3 with dense dark brown scales; markings blackish brown, edged with yellowish white: humeral patch a small spot; costal patch at basal 2/5, somewhat inverted triangular; median patch extending from upper margin of cell to dorsum, its outer margin nearly straight, inner margin convex medially; discocellular stigmata two, elliptical; subterminal fascia yellowish white, angled outwardly at anterior 2/5, then obliquely straight inward to dorsum; terminal dots distinct; fringe yellow, tinged with dark gray. Hindwing and fringe gray. Fore and mid legs yellowish white, with brown belts on dorsal surface; hind leg with femur yellowish brown, tibia dark brown, white at apex, tarsus with each tarsomere blackish brown in basal half, white distal half.
Male genitalia (Fig. 5 f): Uncus with basal half broad, distal half gradually narrowed, slightly curved toward ventral surface, pointed apically. Gnathos with basal 2/5 broad, rectangular, distal 3/5 gradually narrowed to gently hooked tip. Valva broad basally, slightly narrowed to 2/5; costa with basal 1/3 arched, concave medially; ventral margin with basal half nearly straight, distal half blunt; sacculus weak; cucullus slightly widened, about same width as basal part, narrowed to rounded apex distally, setose. Juxta nearly quadrate, anterior margin nearly straight, caudal margin concave in V shape medially; caudal lobe mastoid, bearing setae on dorsal surface. Vinculum narrow. Aedeagus stout, about 3/5 length of valva, broad at base, slightly curved at basal 1/3; cornuti consisting of dense teeth ranging from near base to middle and dense spines in distal half.
Female unknown.
Diagnosis. This species is superficially similar to D. apostatis (Meyrick, 1932) and D. lobigera Gozmány, 1978. It can be easily distinguished from them by the mastoid caudal lobes of the juxta in the male genitalia. In D. apostatis, the caudal lobes of the juxta are digitate (Fig. 4 b); in D. lobigera, the caudal lobes of the juxta are triangular (Fig. 5 e).
Distribution. Thailand.
Etymology. The specific name is derived from the Latin mamillatus (mastoid), referring to the shape of the caudal lobes of the juxta.
