Diagnosis. This species is similar to M. costalis ( Staudinger, 1887) but can be distinguished from it by the following characters: forewing ground color gray; dark brown medial marking broadly waved in outer line near costa; male genitalia with pseudouncus tapering; harpe finger-shaped with dentate; saccus quarter of valva, V-shaped with pointed apex; aedeagus stout, weakly sclerotized, without cornutus; female genitalia with ostium bursae tubular, very slightly sclerotized; ductus bursae membranous, twice length of ostium bursae; and corpus bursae ovoid, with two triangular signa and two long, horizontally broad band-shaped signa.

Redescription. Adult ( Figs 10a, b ). Wingspan 14–18 mm in both sexes. Head and thorax gray in both sexes. Ground color of forewing gray, with dark brown basal patch in costal margin; dark brown medial marking broadly waved in outer line near costa; brown subterminal line waved; cilia gray, mixed with white scales. Hindwing gray; cilia gray. In female, ground color of forewing and hindwing similar as male. Male genitalia ( Fig 21 ). Pseudouncus tapering, weakly covered with setae, subscaphium present. Tegumen circular, almost two-thirds length than valva. Valva elongated rectangular, broadly to the apex, weakly curved inwardly, with rounded apex; costal margin of valva sclerotized. Harpe short, finger-shaped, with dentate dosally. Saccus V-shaped, with pointed apex. Aedeagus slender, weakly sclerotized, without cornutus. Female genitalia ( Fig 33 ). Apophyses posteriores twice length than anteriores. Ostium bursae tubular, membranous. Ductus bursae membranous, twice length than ostium bursae. Corpus bursae ovoid, with two triangular signa and two long, horizontally broad band-shaped signa.
