Type locality: Cambodia ( Cardamon Mts. , Pursat Prov.) .

Type materials. Holotype: ♀, Cardamon Mts. , [nr. Pramaoy], Pursat Prov., 22 Feb 2012, Y.-S. Bae, X.- V. Le, and B.-S. Park (gen. slide JBH–2998; adult photo 11370) ( INUC) (deposited at INUC).

Diagnosis. This species is distinctive for its large orange midwing fascia with its median distal finger-like orange extension to the wing apex. Female genitalia with acute knife-like asymmetrically bifurcate sterigma.

Description. Wing expanse: 16 mm female (n = 1). Female ( Fig. 5 View FIGURES 3–5 ). Head ( Fig. 8 View FIGURES 6–8 ): vertex and frons orange, with yellow on lower frons; white eye marginal scales (frontal and caudally); labial palpus pale yellow to white distally, with dark brown on basal segment and laterally on middle segment; bristles from base to middle segment pale white; antenna purple-brown, with basal 3 segments pale yellow dorsally; scape light yellow. Thorax: orange; tegula purplebrown proximally, then mostly orange to distal end; venter purple-brown; forelegs purple-brown except yellow coxae; mid- and hind legs yellow except purple-brown femurs, distally on tibiae (and purple-brown spurs), and on tarsae. Forewing ( Fig. 5 View FIGURES 3–5 ): lustrous purple-brown, with median wide orange fascia across wing from middle to 2/3, basally concave, and with a narrower and distally acute extension from middle of median fascia to wing apex; a thin orange line along anal margin; fringe purple-brown; venter lustrous dark brown, with thin yellow costal line at 2/3. Hindwing ( Fig. 5 View FIGURES 3–5 ): purple brown, lighter towards base; fringe purple-brown; venter lustrous purple-brown. Abdomen: dark brown to purple-brown, except dark golden on T1; venter yellow-orange; genital tufts purple-brown, but ventrally yellow-orange; pregenital plate (S6) simple, unadorned; S7 fused with sterigmal projections. Female genitalia ( Fig. 11 View FIGURE 11 ): ovipositor very long (ca. 2.5x length of abdomen S6) and narrow; papilla analis small, slightly acute (but not scerlotized as piercing type); apophyses long and slender, with posterior pair somewhat longer than anterior pair; ostium a simple, membranous funnel tube to ductus bursae; sterigma with asymmetrical strongly sclerotized knifelike caudal spines (left spine shorter than right spine, Fig. 11a View FIGURE 11 ) and fused to S7; ductus bursae short (ca. 1.5x bursal length) and narrow, membranous; corpus bursa ovate; signum absent. Male: unknown.

Etymology. The species is named after Cambodia.

Biology. Unknown.

Distribution. Known only from southwestern Cambodia (Pursat), in the Cardamon Mts ( Fig. 12 View FIGURE 12 map).

Discussion. The female of this new species appears somewhat similar to the male of V. panghapha sp. nov., so it is not known if it could be the female of the same species, but it appears to be a distinct third species.
