Nephelomilta suffusa


The N. suffusa   species-group

Diagnosis. Species of the species-group are characterized by the brownish red or ochreous forewing coloration. For the male genitalia the combination of such features as the absence of an apical costal lobe, the presence of the ventral-apical costal process, the absence of a subapical saccular process, and the absence of spines on the medial diverticulum of the vesica is characteristic. The female genitalia resemble those of the N. sumatrana   species-group by the small pheromone glands situated ventrally and the absence of an antevaginal plate, but the long and heavily sclerotized ductus bursae is unique within the genus; in addition, the apophyses anteriores in the N. suffusa   speciesgroup are much shorter than the apophyses posteriores, like in other species-groups, except for the N. sumatrana   species-group.

Description of external morphology. Head brownish red; thorax blackish with two dark reddish spots; abdomen blackish, with admixture of brownish red scales. Forewing coloration brownish red or ochreous brown, with fuscous pattern which is variable within species; subbasal line as spot; antemedial line angled in cell, medial line angled in cell, strongly broadened posteriorly, often connected with antemedial line; postmedial line as curved broad shadow with slightly wavy margins, may be interrupted into several diffuse spots; three large spots in subterminal area, may be connected with postmedial shade; terminal line interrupted into row of small spots on veins; medial spot of cell diffuse, often connects antemedial and postmedial line; discal spot as complex of two dots in males which usually connected with medial line, and V-shaped complex of three dots in females which sometimes merged into V-shaped spot; cilia reddish brown or ochreous brown, with fuscous dots opposite veins. Hindwing reddish brown or ochreous brown, with more or less developed fuscous suffusion; discal spot broad, diffuse; cilia ochreous or blackish brown.
