Deltoplastis mamillata Park & S. Wang View in CoL , sp. nov.

( Figs. 3 View FIGURE 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 View FIGURE 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 View FIGURE 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 View FIGURE 4 b); in D. lobigera , the caudal lobes of the juxta are triangular ( Fig. 5 View FIGURE 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.
