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

( Figs. 3 View FIGURE 3 h, 6c, 8c)

Type Material. Holotype ♂, Thailand: Mae Hong Son, Sop Pong, 21.VII.2009, coll. Y. S. Bae & D. Y. Chae, genitalia slide No. NK-WYQ1402. Paratypes: 1♂, 2♀, same data as the holotype except dated 20–22.VII.2009. Types are deposited in KNA.

Description. Adult ( Fig. 3 View FIGURE 3 h) with wingspan 16.0–17.0 mm. Head yellowish brown, white around compound eye. Antenna yellowish white. Labial palpus with second segment grayish white on inner surface, blackish brown on outer surface, terminal white; third segment yellowish white on inner surface, ocherous brown on outer surface. Thorax and tegula yellowish brown. Forewing with costal margin almost straight, apex protruding triangularly, termen concave from below apex; ground color pale yellow, black along distal part of costal margin along apex and termen to dorsum distally; markings blackish brown, edged with yellowish white: humeral patch extending to basal 1/8 of costal margin; median patch large triangular, extending from below costa to dorsum, its lower margin about 1/2 length of dorsum, outer margin nearly oblique; discocellular stigma spoon-shaped, its anterior half roundly expanded; 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 1/4; subterminal fascia yellowish white, slightly arched outwardly at anterior 2/5, followed by a broad zone with dense deep gray scales; fringe pale gray, basal line yellowish white. Hindwing and fringe deep gray, fringe pale yellow on tornus, basal line yellowish white. Fore and mid legs yellowish white, scattered with brown scales; hind leg with femur and tibia dark brown, tarsus yellowish white.

Male genitalia ( Fig. 6 View FIGURE 6 c): Uncus broad at base, narrowed to apex. Gnathos broad at base, narrowed to middle, obviously slender and hooked distally. Valva broadest at base, narrowest at middle; costa with basal 1/5 squarely protruded, semicircularly concave medially; ventral margin with basal half straight, ventro-distal corner bluntly arched; sacculus about 1/3 length of valva; cucullus triangular, upturned obliquely, narrowed to rounded apex, outer margin gently rounded. Juxta quadrate, convex medially on anterior margin, slightly concave on caudal margin; caudal lobe short tooth-like, bearing setae apically. Vinculum narrow. Aedeagus as long as valva, curved at basal 1/3; cornuti consisting of a round plate of clustered short conic spines at distal 1/6 and a longitudinal band of clustered spines extending from basal 2/5 to 4/5 as well as a curved thorn situated distally.

Female genitalia ( Fig. 8 View FIGURE 8 c): Abdominal sternite VIII with caudal margin medially concave. Papillae analis rounded posteriorly, setose. Apophyses anteriores about 3/4 length of apophyses posteriores. Ductus burse longer than corpus bursae, basal 1/5 slightly thin, distal 4/5 thick; ductus seminalis arising from posterior 1/4 of ductus bursae. Corpus bursae oval; signum elongate subrectangular, as long as 1/2 length of corpus bursae, with dense minute granules in anterior 2/3 and stronger teeth in posterior 1/3.

Diagnosis. This species is superficially similar to D. commatopa Meyrick, 1932 and D. figurodigita Wu & Park, 1998 . It can be distinguished them by the juxta convex medially on the anterior margin, and the caudal lobes of the juxta tooth-like in the male genitalia; and by the subrectangular signum in the female genitalia. In D. commatopa , the anterior margin of the juxta is bluntly rounded and the caudal lobes of the juxta are indistinct ( Fig. 4 View FIGURE 4 d); and the signum is nearly rounded ( Fig. 7 View FIGURE 7 c); in D. figurodigita , the anterior margin of the juxta is straight and the caudal lobes are short digitate ( Wu & Park, 1998: 3, Fig. 8 View FIGURE 8 ).

Distribution. Thailand.

Etymology. The name specific name is derived from the type locality.
