Diagnosis. Agrisius leloii  sp. nov. ( Figs 9, 10 View Figure ) is externally very similar to A. japonicus  (subspecies japonicus  and dubatolovi  ) ( Figs 1, 2, 5, 6 View Figure ), and can be reliably distinguished from them only by the genitalia structure. The male genitalia of A. leloii  sp. nov. ( Figs 26 View Figure , 27 View Figure ) differ clearly from those of A. japonicus  ( Figs 21–24 View Figure ) by the much broader valves, the more robust and stronger curved distal saccular process, and the uncus structure: in A. leloii  sp. nov. the basal plate of the uncus is significantly longer and broader, the medial dorsal crest is reduced to a small trigonal process with a rounded tip, the distal branches of the uncus are much longer, with short and trigonal apicaldorsal processes and claw-shaped apexes with additional short thorn on their ventral surfaces; these apexes are curved downwards. The female genitalia of A. leloii  sp. nov. ( Fig. 36 View Figure ) differ from those of A. japonicus  ( Figs 33, 34 View Figure ) by the presence of the large and heavily sclerotized antevaginal plate, the absence of the sclerotized area in the ductus bursae, and the much longer, band-like signa.

Description. Adult ( Figs 9, 10 View Figure ). Forewing length 22.5–25.5 mm in males and 23.5– 27 mm in females. Forewing narrow with elongated towards apex, its ground color brown. Forewing pattern consists of series and rows of blackish spots in inner part of wing: wing base with one small spot; subbasal row consists of three spots; one additional small spot is situated on radial vein between subbasal and antemedial rows; antemedial row consists of six spots of different size; one additional small spot is situated in cell outwards from antemedial row; postmedial row consists of nine spots of different size and strongly curved on cell. In forewing outer part, veins dark brown, alternating with indistinct darker strokes between veins. Hind wings somewhat paler than forewing, brown with darker veins. Male genitalia ( Figs 26 View Figure , 27 View Figure ). Uncus consists of long and broad basal plate, which has small, trigonal, apically rounded dorsal crest, and two long distal branches, which have short and trigonal apical-dorsal processes and claw-shaped apexes which are curved downwards, with additional short thorn on their ventral surfaces; tegumen short, moderately sclerotized; penicular lobes broad, with coremata; tuba analis broad, with heavily scleroized, plate-like subscaphium; juxta large, heavily sclerotized, hood-like; vinculum heavily sclerotized, Vshaped. Valve lobe-like, membranous, distally broadened; costa weakly sclerotized, short and broad, with ventrally directed cuneal extension; sacculus short and narrow, with one heavily sclerotized curved extension. Aedeagus small and narrow, with long and curved coecum; vesica curved ventrally at base, with distally directed narrow and short subbasal diverticulum. Female genitalia ( Fig. 36 View Figure ). Ovipositor short, conical; papillae anales broad, with weak setae; VIII abdominal segment moderately sclerotized; apophyses short and broad, apophyses posteriores broader and longer than apophyses posteriores. Ostium bursae narrow. Antevaginal plate large, heavily sclerotized, with rounded lateral lobes and narrowly rectangular anterior part. Ductus bursae long, narrow, membranous, S-like curved; corpus bursae extremely long, membranous, drop-like, with two extremely long and narrow, band-shaped signa, which consist of two plates each and are spiked.

Distribution. The species is known from Сentral Vietnam (Da Nang, Quang Ngai and Gia Lai provinces).

Etymology. The species name is dedicated to Le Loi, the most famous man of Vietnamese history and one of its greatest heroes.
