Description

Male. Length of fore wing: 27–28 mm. Frons and terminal half of palpus brown to pale brown. Antenna shortly bipectinate, with blackish grey rather than brown branches, as in other species. Abdominal crests bright yellow brown, without metallic gloss. Wing shape as in M. arenaria (Leech) , the outer margins perfectly rounded, not produced at the ends of veins. Wing colour white scattered with sparse brown or grey scales, markings yellowish brown to grey on upperside, without purple lustre of other species. Fore wing with a basal yellow-brown patch, extending to postmedian fascia along costa; antemedian line consisting of some interrupted black streaks; discal spot large, partly ringed with blackish brown; postmedian fascia with a row of greyish brown spots and a thin line distally to the spots, the line bluntly angled on M 1 and M 3; a broad yellowish brown subterminal band interrupted at middle, and grey at apical area. Hind wing with discal spot, postmedian fascia and subterminal band lighter and greyer than on fore wing. Underside with a weak tinge of violet, markings dark greyish brown; marking patterns as in M. arenaria (Leech) , the postmedian fascia placed more distally, and sharply angled on M 3, while on hind wing very deeply curved outwards; subterminal band as on upperside, but darker.

Male genitalia ( Figure 66 View Figures 65–67 ). Close to M. arenaria (Leech) . Socii short and broad. Shape of valva differs in more distinct angle at middle of saccular margin and much narrower terminal half. Terminal part of central basal lobe of valva slightly broadened. Saccular process more produced. The additional small bubble-like sclerite on vesica larger and rounder than in M. arenaria .

Female. Unknown.
