Volynkin, Anton V., Dubatolov, Vladimir V. & Kishida, Yasunori, 2018, On the taxonomy of the genus Agrisius Walker, 1855, with descriptions of two new species from Vietnam and Laos (Lepidoptera, Erebidae, Arctiinae), Zootaxa 4459 (1), pp. 128-138 : 129

The Agrisius japonicus species group

The species group was established and substantiated by Dubatolov & Kishida (2013). Moths are large, with brownish-grey or whitish body and wing coloration ( Figs 1–6 ). The forewing pattern consists of several rows of black dots in the basal area and the cell, the blackish suffusion on veins in the distal area of forewing, and is characterized by the absence of a spot in the distal section of the cell, which is well developed in the A. guttivitta species-group ( Figs 11–20 ). The male genitalia of the species group ( Figs 21–25 ) have the complex uncus consisting of the basal plate with a dorsal lobe-like rounded crest, and two short distal branches, which have the apical-dorsal processes curved upwards toward the dorsal lobe-like rounded crest and armed with row of spinules on their apical margins; the membranous elliptical valves have no coremata apically; the coremata are present on the penicular lobes; the aedeagus is narrow, without cornuti or spinules in the vesica. The female genitalia ( Figs 33–35 ) are characterized by the narrow, weakly sclerotized ductus bursae with no antrum.
