This new species is characterized by the forewing having an inverted irregular V-shaped tornal spot. It can be distinguished from the similar-looking species by the valva with two large ventroapical spines hooked dorsad, and with a large semicircular protuberance beyond the middle of the costa. Description. Adult ( Fig. 4 ) wingspan 8.5−9.0mm. Head with vertex snowy white, frons silvery gray, occiput pale reddish brown. Labial palpus with second segment yellow to brownish yellow; third segment blackish brown except white at apex. Antenna with scape white; flagellum black, dorsal surface white on basal several flagellomeres, alternated with white on remaining flagellomeres. Thorax and tegula pale reddish brown. Forewing yellow, markings white edged with black scales: basal fascia from base of fold obliquely straight outward; antemedian fascia wider, sub-parallel with basal fascia, arched outward slightly, reaching upper margin of cell; costal spot sub-rectangular, slightly narrowed posteriorly, extending from distal 2/5 obliquely outward, crossing upper corner of cell ventrally; tornal spot irregularly inverted V shaped, its outer arm large, inner arm shorter and slenderer; apical spot round; two pre-apical spots placed on termen, much smaller than apical spot; cilia yellow except gray around tornus. Hindwing and cilia deep gray. Fore- and midlegs black, fore tibia with two white dots and a small apical tuft of white scales, mid tibia with a white tuft of long scales, fore and mid tarsi white at apices of first and second tarsomeres counting from base; hindleg whitish yellow on ventral side, grayish brown on dorsal side except tarsus whitish yellow at apex of each tarsomere. Male genitalia ( Fig. 12 ): Uncus wide basally, narrowed distally, rounded apically. Gnathos strong, longer than uncus, trapezoidal, straight apically. Tegumen divided from about posterior 1/4, narrowed anteriorly to rounded apex, sclerotized along edges. Valva wide at base, slightly narrowed to apex; costa concave before middle, with a large semicircular protuberance from beyond middle to before apex; ventral area setose from end of sacculus to apex, produced to two large ventroapical spines hooked dorsad. Sacculus wide at base, slightly narrowed to 2/3 of ventral margin of valva. Saccus shorter than uncus, broad triangular, rounded at apex. Juxta sub-rounded; lateral lobe slender, with sparse setae. Aedeagus stout, almost as long as valva, with wrinkles distally; cornutus large, slightly shorter than half length of aedeagus, its basal 2/3 rhombic, distal 1/3 slender, with strong spines. Female genitalia ( Fig. 16 ): Apophyses posteriores approximately twice as long as apophyses anteriores. Sternum quadrate, with fine setae on posterior margin; tergum large, rounded on posterior margin. Ostium bursae large and rounded. Antrum strong, almost uniform. Ductus bursae membranous, coiled medially, with a wide banded sclerite extending from antrum to corpus bursae. Corpus bursae elongate ovate, granulous, with two sclerotized sub-rectangular plates of granules; signum being a large rectangular plate with granules and denticles. Distribution. Cambodia ( Mondulkiri , Pursat ). Etymology. The specific epithet is derived from the Latin apex and uncatus (hooked), referring to the hooked ventroapical spines of the valva.
