Notonagemia analis
Outer margin of forewing not undulate as in Meganoton nyctiphanes and Cerberonoton rubescens, but shallowly sinuate anterior to hind angle. Palpus with 2nd segment smaller than in Meganoton nyctiphanes and Cerberonoton rubescens. Hindtarsus first segment with 2nd row of spines extending close to the base, as in Psilogramma. 8th abdominal tergite without stridulatory scales on the inner surface.
Male genitalia: Uncus divided into 2 long and slender processes that are regularly curved ventrad and gradually narrowed to a point; the processes becoming closer a little beyond their midlength. Gnathos produced into a long cylindrical process, slightly bent downward at the apex, which is obtuse. Valve sole-shaped, the dorsal margin bent inwards; a large clay-coloured patch of large, multidentate, ribbed, stridulatory scales present; subdorsal longitudinal groove sharply defined, deep, the fold below it with long bristles. Harpe ladle-shaped, minutely dentate. Phallus with one pointed process that is broad at its base.
Female genitalia: Ostial plate only lightly sclerotized, the entire post-ostial part membranous and scaled; the ante-ostial part also membranous; a narrow sclerotized stripe extends to each side from the ostial cavity; the upper edges of these plates continuous, forming an arcuate ridge that borders the ostial cavity posteriorly; the proximal edge of the cavity formed by a very thin membranous fold, which is preceded by a stronger fold.
