Antillocladius yakyijeus (Sasa et Suzuki) ; Yamamoto (2004: 4) . Material examined: Holotype as in Sasa and Suzuki (2000) ( NSM ). JAPAN : Mie Prefecture : Toba city, Futami-chyo , 6 males , 18.v.1985 , T. Hirabayashi. Diagnostic characters: The male can be separated from all other members of the genus by having numerous apical setae on the wing membrane, cell m 3+4 bare; setose squama; acrostichals starting close to antepronotum, all scalpellate; long virga; anal point long, tapering, with moderately strong lateral setae; and inferior volsella prominent with anterior digitiform projection equally long as and partly covering rounded posterior lobe. Remarks: Antillocladius pluspilalus , A. yakyijeus , A. scalpellatus and A. subnubilus are only separable on the size of the virga and the chaetotaxy of squama and cell m 3+4 . See A. pluspilalus for comments. Distribution: The species is known from Japan .
