( Figs. 14 View FIGURES 1 – 21 , 35 View FIGURES 22 – 40 , 54, 54 View FIGURES 52 – 55 a –b)

Holotype: ♂, CAMBODIA, Kep, 11 xi 2011 (YS Bae et al.), gen slide no. CIS- 6437.

Diagnosis. This new species is easily distinguished from its allies by having very characterized the male labial palpus which is shortly developed and visible, while the third segment atrophied in most known species, and the second segment with an additional, upturned scale tuft arising from base of inner surface.

Description. Adult: Male ( Figs. 14 View FIGURES 1 – 21 , 35 View FIGURES 22 – 40 ). Wingspan, 11 mm. Head pale brownish gray on dorsal surface, blackish on face, with brownish scales laterally. Flagellum of antenna with indistinct brownish annulations. Second segment of labial palpus in male ( Fig. 35 View FIGURES 22 – 40 ) very large, quadrate, with scale tuft antero-ventrally, longer than width of head, densely covered with dark brown scales on outer surface; inner surface black, shiny, except median white zone beyond middle, with an additional upturned scale tuft arising from base, upturned; third segment shortly developed, visible. Tegula covered with blackish scales on anterior half, brownish scales on posterior half. Thorax brownish dorsally. Forewing elongate; ground color brownish orange, mottled with dark brown scales; a small black streak near base of cell; a longitudinal long blackish streak near base to 2 / 5 along plical line, discal streak black, as long as 1 / 5 the length of forewing, and another blackish streak from end of cell toward costa before apex; costa nearly straight; costal patch elongate preceded by the similar, smaller dots and followed by three smaller ones on costa; long whitish hair pencil on the underside of the forewing absent; apex more or less obtuse; termen oblique; fringe grayish. Hindwing elongate, grayish white, hyaline before middle, brownish scales along veins; broad anterior expansion on costa extended to middle, then oblique; apex acute.

Male genitalia ( Figs. 54, 54 View FIGURES 52 – 55 a –b): Abdominal sternite VIII convex on caudal margin, with pocket-like lateral sacs on anterior margin ( Fig. 54 View FIGURES 52 – 55 b). Uncus short, with acute apex, downward apically; socius elongate. Tegumen as long as valve, with almost parallel sides. Valvae asymmetrical, but more or less similar; left valva large, elongate, with a protrusion near basal 1 / 3 on dorsal margin; ventral margin convex beyond middle, without sclerotized basal process; patch of modified scales in distal 1 / 6. Right valve slender, narrower beyond 2 / 3; patch of modified scales as in left valva. Phallus taenioid, terminated with sclerotized spine-like process apically, about 2 / 3 the length of valva.

Distribution. Cambodia (Kep).

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