( Figs 2 , 14 , 25 )

Roeselia protogigas Inoue, 1970: 3–4 . TL: Japan (Ichibata, Shimane Pref.).

Roeselia protogigas: Choi, 2006: 186–187 .

Meganola protogigas: Inoue, 1982: 665 ; Sasaki, 2011: 179.

Diagnosis. This species is similar to Meganola triangulalis ( Leech, 1888) but can be distinguished from it by the following characters: forewing ground color ground color pale gray to fuscous gray; postmedial line not begin medial patch; male genitalia with tegumen not tumescent at basal area; valva weakly excurved at basal area; harpe well-developed triangular-shaped; sacculus developed; aedeagus short length, without dentation; female genitalia with ostium bursae sclerotized long elliptical; ductus bursae short, narrow; and corpus bursae with cervix bursae two signa present.

Redescription. Adult ( Figs 2a, b ) Wingspan 22–30 mm in both sexes. Head and thorax bright gray in both sexes. Ground color of forewing gray, with dark brown hemicircular costal patch in male, female darker than male. Postmedial line broadly waved in outerline near costa; cilia gray, mixed with black scales. Ground color of hindwing bright gray in male, darker in female; cilia gray in both sexes. Male genitalia ( Fig 14 ). Pseudouncus tapering weakly covered with setae on dorsal side. Tegumen triangular. Valva elongated rectangular, weakly curved inwardly, with blunt apex; costal margin of valva sclerotized. Harpe triangular, with dentate distally. Saccus V-shaped. Aedeagus slender, without cornutus ( Choi (2006): 186, fig. 2; in present paper: Plate 4. 16). Female genitalia ( Fig 25 ). Apophyses posteriors twice length than anteriores. Ostium bursae strongly sclerotized, relatively thick than ductus bursae. Ductus bursae membranous, with small cervix bursae. Corpus bursae with two triangular signa.
