Type locality: Thailand ( Pangha Pha Pass , Mai Hong Son Prov.) .

Type materials. Holotype: ♁, Pangha Pha Pass (868m) [near Soppong], Mai Hong Son Prov., Thailand, 27 Jul 2009, J. B. Heppner (gen. slide JBH–3197; adult photo 12222) ( MGCL) (deposited at MGCL).

Diagnosis. This species is distinctive in the forewing having a basal orange mark besides the midwing orange fascia, the latter also without an extension to the apex (with apical finger-like extension in V. cambodiensis sp. nov.). Male genitalia with basal appendage on valvae.

Description. Wing expanse: 13.5 mm male (n = 1). Male ( Fig. 4 ). Head ( Fig. 7 ): vertex orange; frons yellow and laterally; caudal eye margin yellow; labial palpus yellow-white, with distal segment lighter and dark brown on basal segment, and bristles dark brown; antenna purple-brown, with light yellow segments on basal 5 segments and at 4/ 5 in short section; scape yellow. Thorax: golden-yellow to orange; tegula purple-brown to golden distally; venter purple-brown; forelegs purple-brown except yellow coxae, with remainder of legs golden except purplebrown markings at joints and dorsally on tarsi. Forewing ( Fig. 4 ): lustrous dark brown, with dark orange fascia from costa at 2/5 and recurved to wing base, and wide orange fascia at midwing and with concave emargination by tornus; fringe purple-brown and long from before apex to tornus; venter lustrous dark brown, with light yellow patch on tornus. Hindwing ( Fig. 4 ): pale bronze-brown, with purple-brown near apex; fringe purple-brown from before apex to tornus; venter lustrous dark brown. Abdomen: dark brown, with metallic bronze iridescence, with paler caudal marginal scales per tergite; venter light brown with bronze iridescence, with segmental caudal margins creamwhite; genital tufts brown with bronze iridescence; S6 caudally convex, medially conical. Male genitalia ( Fig. 10 ): tegumen-vinculum as fused cylinder, with strong dorsal transtilla-like semi-circular ring; uncus undeveloped and membranous; medial linear subscaphium on diaphragma; valva quadratic and setose, with saccular margin strongly developed and densely setose and basally abruptly convex before basal joint; valval base with small triangular apically acute setose appendage; juxta-anellus complex as dorsal convex collar with lateral extended flattened arms to lateral semi-circular flattened ends; short oblong basal stylus plate; saccus short; aedeagus narrow and long, cornutus a single long thin tubule (subequal to aedeagus length and width). Female: unknown.

Etymology. The species is named for the type locality, Pangha Pha Pass, northwestern Thailand (northwest of Chiang Mai).

Biology. Unknown.

Distribution. Known only from far northwestern Thailand (Mai Hong Son) ( Fig. 12 map).

Discussion. The new species is closest to V. cambodiensis sp. nov., known only from the female, and could possibly be the male of the same species, but it seems to be a separate species.
