Metriocnemus yakyijeus Sasa and Suzuki, 2000: 88 , Fig. 47 .

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.
