Diagnosis. This species is similar to Meganola gigas ( Butler, 1884) but can be distinguished from it by the following characters: ground color slightly brown gray; postmedial line begin to subterminal patch; male genitalia with tegumen tumescent at basal area; valva not excurved; harpe finger-shaped without dentation; aedeagus long as valva, waved; female genitalia with ostium bursae strongly sclerotized triangular-shaped; ductus bursae weakly sclerotized, almost same length as ostium bursae; cervix bursae half-length of ductus bursae, with horizontally band-shaped signum.

Redescription. Adult ( Figs 3a, b ). Wingspan 28–30 mm in both sexes. Head and thorax gray in both sexes. Ground color of forewing gray, with two dark brown hemicircular patch on costal margin; dark brown antemedial line waved, medial and postmedial lines waved; dark brown subterminal line waved; cilia gray, mixed with white scales. Ground color of hindwing gray; cilia gray in both sexes. Male genitalia ( Fig 15 ). Pseudouncus tapering, weakly covered with setae. Tegumen triangular. Valva elongated, weakly curved inwardly, with rounded apex; costal margin of valva sclerotized. Harpe short, slender stick-shaped. Saccus elongated, blunt V-shaped. Aedeagus slender, almost same length as valva, weakly sclerotized, without cornutus. Female genitalia ( Fig 26 ). Apophyses posteriores half-length of anteriores. Ostium bursae triangular, strongly sclerotized. Ductus bursae weakly sclerotized, almost same length as ostium bursae. Cervix bursae relativelty large than ductus bursae. Corpus bursae ovoid, with a horizontally band-shaped signum; appendix bursae present.
