Diagnosis. This species is similar to M. strigulosa ( Staudinger, 1887) but can be distinguished from it by the following characters: forewing ground color pale gray; dark gray medial marking broadly waved in outer line, without excurved; male genitalia with pseudouncus ovoid; valva stout, with vasally setae; harpe short, slender, weakly curved, with apical pointed finger-shaped; saccus half-length than valva; aedeagus slender, weakly sclerotized, slightly curved; female genitalia with ostium bursae slender; and corpus bursae with two triangular signa larger than M. strigulosa .

Redescription. Adult ( Figs 9a, b ). Wingspan 20–24 mm in both sexes. Head and thorax gray in male, dark gray in female. Ground color of forewing brown-gray in male, darker in female, 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 dark brown scales. Ground color of hindwing pale brown in male, darker in female; cilia pale brown in both sexes. Male genitalia ( Fig 20 ). Pseudouncus ovoid, weakly covered with setae on dorsal side, subscaphium present. Tegumen triangular, almost same length as saccus. Valva elongated rectangular, weakly curved inwardly, with rounded apex, basal area hairy. Costal margin of valva sclerotized. Harpe short, slender, weakly curved, with apical pointed hook-shaped. Saccus elongated V-shaped. Aedeagus slender, weakly sclerotized, slightly curved, without cornutus. Female genitalia ( Fig 32 ). Apophyses posteriores almost same length as anteriores. Ostium bursae broad, sclerotized, funnel-shaped. Ductus bursae membranous, tubular, half-length of corpus bursae. Corpus bursae ovoid, with two triangular signa medially and two long, horizontally band-shaped signa.
