Meganola fumosa ( Butler, 1879)

( Figs 12 , 23 , 35 )

Nola fumosa Butler, 1879: 9 . TL: Japan (Yokohama Pref.). Rhynchopalpus fumosa: Tshistjakov, 2008: 15–16 .

Meganola fumosa: Inoue, 1982: 667 ; Oh, 1991: 78–80 [unpublished]; Sasaki, 2011: 180. Diagnosis. This species is similar to M. mediofascia ( Inoue, 1958) but can be distinguished from it by the following characters: ground color of forewing gray; medial marking broadly curved; male genitalia with pseudouncus sharp, long, with an apical small spine, almost same length as tegumen; valva costal margin minute dentate; harpe slender, hook-shaped; saccus one-fifth than valva; aedeagus robust; female genitalia with ostium bursae tubular; corpus bursae, with two signa, anterior signum twice length than posterior, band-shaped signa absent; and appendix bursae present.

Redescription. Adult ( Figs 12a, b ). Wingspan 14–20 mm in both sexes. Head and thorax dark gray in both sexes. Ground color of forewing dark gray in male, brighter 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; cilia pale brown in both sexes. Male genitalia ( Fig 23 ). Pseudouncus sharp, long, with an apical small spine, almost two-thirds length than tegumen. Tegumen triangular. Valva elongate, straight, with rounded apex; costal margin of valva sclerotized. Harpe short, slender, hook-shaped. Saccus V-shaped, half-length of pseudouncus. Aedeagus weakly sclerotized, with cornutus. Female genitalia ( Fig 35 ). Apophyses posteriores twice length than anteriores. Ostium bursae tubular, membranous. Ductus bursae membranous, half-length of corpus bursae. Corpus bursae ovoid, with two triangular signa, posterior signa two-thirds length than anterior; appendix bursae present.
