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 : 130

( Figs 5, 6 , 23, 24 )

Agrisius dubatolovi Orhant, 2012 , Bulletin de la Société Entomologique de Mulhouse 68 (3): 37, Figs 4–6 (Type lOcality: Thailand, " Kanchanaburi, SOng TOh Mine , 831 M. ").

Material examined: 1 ♂, Vietnam, Cao Bang, Mt. Pia Oac , 1700 m, III.2002, slide AV1690 ♂ (Coll. SZMN) ; 1 ♂, China, Guangxi, Jiuwandashan , VI.2003, Wang Min leg., prep. Dubatolov (Coll. SZMN) ; 1 ♂, Hainan Isl., China, Diaoluashang, near Resort hotel, alt. 750/ 900 m, 24.V.2004, LT, K. Ueda leg., prep. Dubatolov (Сoll. SZMN).

Remark. This taxon was described by Orhant (2012) as a valid species without comparison with its closest relative A. japonicu s Leech, 1889, and later Dubatolov & Kishida (2013) have suggested that dubatolovi might be a subspecies of japonicus . The detailed comparison of its male genitalia ( Figs 23, 24 ) demonstrated its conspecificity with A. japonicus ( Figs 21, 22 ). Nevertheless, dubatolovi has several morphological differences from A. japonicu s japonicu s therefore, here we treat it as a valid subspecies of A. japonicus .

Diagnosis. Agrisius japonicus dubatolovi ( Figs 5, 6 ) is externally very similar to A. japonicu s japonicu s ( Figs 1, 2 ) by grey wing coloration, but differs by the slightly larger size and the somewhat narrower forewing. Both those subspecies are geographically separated by A. j. albida Daniel, 1952 , which has whitish wing coloration. The male genitalia of A. japonicus dubatolovi ( Figs 23, 24 ) differ from those of two other subspecies ( Figs 21, 22 ) by the uncus shape, which has the longer dorsal processes of its distal branches (thus, the distance between the apex of the dorsal process and the lobe-like rounded crest is the shortest, compared with other subspecies of A. japonicus ), and also by the smaller vinculum and the somewhat longer distal saccular process.

Distribution. South Сhina (Guangdong, Hainan), Indochina ( Vietnam, Thailand).
