Agrisius leloii


The A. leloii  species-group

Agrisius leloii  sp. nov. ( Figs 9, 10 View Figure ) is very close to the A. japonicus  species-group ( Figs 1–8 View Figure ) by its external appearance, the long basal plate of the uncus with medial dorsal crest, the hood-like juxta, the absence of coremata on the apex of the valve (only longer hairs presented), the presence of only one, short saccular process, and the absence of cornuti and spinules in the aedeagus vesica, but the long distal branches of its uncus ( Figs 26 View Figure , 27 View Figure ) are very different from those of the A. japonicus  species-group ( Figs 21–25 View Figure ) and resemble those of the A. guttivitta  species-group ( Figs 28–32 View Figure ). However, in the A. guttivitta  species-group those branches are not curved dorsoventrally and are pointed apically, whereas in A. leloii  sp. nov. the distal branches of the uncus have the short and trigonal apical-dorsal processes similar to those of the A. japonicus  species-group, but differ from the latter by the claw-like apexes, which are curved downwards (in the A. japonicus  species-group they are curved upwards). The female genitalia of A. leloii  sp. nov. ( Fig. 36 View Figure ) differ from those of the A. japonicus  species-group ( Figs 33, 34 View Figure ) by the presence of a heavily sclerotized antevaginal plate, and from the A. guttivitta  species-group ( Figs 37–41 View Figure ) by the absence of heavily sclerotized antrum. Taking into account all listed genitalic characters, we treat A. leloii  sp. nov. as a member of the separate species-group, which is morphologically intermediate between the A. japonicus  and the A. guttivitta  species-groups.
