description: Deltoplastis curviloba Park & S. Wang, sp. nov.
(Figs. 2 g, 4f)
Type material. Holotype: ♂, Thailand: Loei Province: Phu Luang Wildlife Sanctuary, 700–900 m, 8–14.X.1984, coll. O. Karsholt, O. Lomholdt & E. Nielsen, genitalia slide No. CIS-6246/Park. Paratypes: 2♂, same data as the holotype. The holotype is deposited in ZMUC and paratypes in KNA.
Description. Adult (Fig. 2 g) with wingspan 11.0– 12.5 mm. Head creamy white. Antenna with scape white on dorsal surface, brown on ventral surface; flagellum brown with white. Labial palpus with second segment white on inner surface, pale brown on outer surface, with scattered dark brown scales; third segment white on inner and outer surface except brown on dorsal and ventral surface. Thorax yellowish white, tegula yellowish white except dark brown at base. Forewing with costal margin nearly straight, apex obtuse, termen slightly concave medially; ground color yellowish white, with scattered brown scales, dark brown from distal 1/6 of costal margin, along apex and termen to tornus; markings deep yellowish brown: humeral patch rectangular; costal patch at basal 2/5, outwardly oblique; median patch subtriangular, extending from below upper margin of cell to dorsum; discocellular stigma a short stripe; subterminal patch nearly trapezoidal, its outer margin extending from costal margin to dorsum, inner margin about 1/3 width of forewing; subterminal fascia obliquely inward; fringe yellowish white, mixed with pale yellow scales. Hindwing and fringe gray. Fore leg white on dorsal surface, brown on ventral surface; mid leg white, mixed with brown scales; hind leg with femur and tibia yellowish brown, tibia blackish brown at apex, tarsus with each tarsomere blackish brown in basal half, white in distal half.
Male genitalia (Fig. 4 f): Uncus broad at base, gradually narrowed to blunt apex, slightly curved toward ventral surface. Gnathos relatively small, not obviously hooked distally. Valva slightly broad at base, narrowed to basal 2/ 5; costa shallowly concave medially; ventral margin concave at about 2/5; sacculus nearly triangular, broad at base, narrowed to end, about 1/5 length of valva; cucullus nearly semilunar, narrowly rounded apically. Juxta nearly semicircular, anterior margin rounded, caudal margin semicircularly concave at middle; caudal lobe slender, curved outwardly before apex, pointed apically, slightly shorter than juxta. Vinculum narrowed, anteriorly produced triangularly. Aedeagus shorter than valva, slightly broad at base, nearly parallel sided from basal 1/4 to 3/4, with two to three large, hooked apical throns; cornuti consisting of dense spinules at basal half, a weak plate of clustered scale-like flakes at middle, a bunch of spines distally.
Female unknown.
Diagnosis: This species is superficially similar to D. scopulosa (Meyrick, 1910). It can be distinguished from the latter by the valva with cucullus nearly semilunar, and the juxta with clavate caudal lobes in the male genitalia. In D. scopulosa, the cucullus of the valva is falculate, and the caudal lobes of the juxta are very short (Clarke, 1965: 43, Pl. 21, Fig. 1).
Distribution. Thailand.
Etymology. The specific name is derived from the Latin curvus (curved) and -lobus (lobe), referring to the juxta with curved clavate caudal lobes.
