Volynkin, Anton V. & Černý, Karel, 2018, Revision of the genus Nephelomilta Hampson, 1900, with descriptions of twelve new species and two new subspecies (Lepidoptera, Erebidae, Arctiinae), Zootaxa 4472 (3), pp. 401-451 : 411

The N. effracta species-group

Diagnosis. All three species of the species-group have the whitish ground color of forewings and the red pattern, which is significantly reduced in N. pseudoeffracta . The male genitalia of the species-group are characterized by the weakly developed medial costal angle, the broadened distal section of the valve, which forms a broad but short apical costal lobe, the distally broadened ventral costal plate, the broad, lobe-like ampulla with rounded margin, and the absence of a distal membranous lobe of valva. The female genitalia structure has no significant differences from that of the N. pusilla and N. chalcedona species-groups.
