Description. Male ( Figs. 4–5, 7View FIGURES 1–10). Forewing length 11–12.5 mm. Forewing ground color dark yellow (in light color form) or pale brown (in dark color form) with a darkening along costal Vein eXtending beyond discal Vein. Postdiscal band dark brown, reduced into costal dash and often to short dash in hind part of the wing. Forewing dorsum noticeably conVeX in basal half, its outer margin narrowly folded inwards. Hindwing yellow. Male genitalia ( Figs. 25–26View FIGURES 24–26). Uncus simple, long; distal section of ValVe with straight costal and Ventral margins, apeX broadly rounded from costa to outer margin, but Ventrally slightly rounded; harpe-like fold U-shaped, reached sacculus apeX; distal saccular process short, bulbed subapically, and with apeX curVed dorsally; aedeagus short, moderately broad, Vesica with 3 diVerticula and field of granulation, one of them is wide; Vesica ejaculatorius situated subbasally. Female ( Figs. 6, 8View FIGURES 1–10). Forewing length 12-14 mm. Forewing ground color dark yellow (in light color form) or pale brown (in dark color form), with a row of 5 black spots of different size and shape, the middle one shifted outwards; hindwings pale yellow. Female genitalia ( Fig. 37View FIGURES 36–41). OVipositor short and broad; apophyses long and thin, apophyses anteriores slightly longer than apophyses posteriores; ductus bursae short, narrow, membranous, with round, bulbous Ventral plate; corpus bursae long, narrow, pear-like, membranous, with one barshaped signum; appendiX bursae short, bulbous, situated latero-posteriorly.

Remarks. The species has two color forms occurring sympatrically. EXternally, male of the new species differs from M. orientalis  by the narrower forewing, darker forewing ground color, smaller dark costal dash and presence of a short dash in the hind part of the wing; female differs from M. orientalis  by the slightly smaller size and smaller black spots on forewing. The male genitalia structure is similar to that of M. orientalis  , but the harpe-like fold is broader, the sacculus apeX is shorter and claw-like curVed, and the apical diVerticulum of Vesica is shorter, less curVed and has no apical spine. The female genitalia differ from those of M. orientalis  by the longer apophyses anteriores and posteriores, the much larger postVaginal plate, the corpus bursae shorter and narrower anteriorly, and the larger appendiX bursae.

Distribution. The species is widespread in Thailand and Vietnam.

Etymology. The species name is dedicated to Dr. Karel Černý (Innsbruck, Austria), who firstly reported and illustrated the species for Thailand as Prabhasa venosa (Černý & Pinratana 2009)  .
