In addition, I found Bentyra from Japan . In this study, I newly record this genus from Japan and review Chirotica and Paraphylax . The Japanese genera can be distinguished by the following key. Key to Japanese genera of Chirotica genus group 1. Upper tooth of mandible longer than lower tooth. Mesoscutum with a median longitudinal groove on the median lobe in Japanese species ( Fig. 63G ). ……………………..… Bentyra Cameron, 1905 -. Upper tooth of mandible as long as or slightly shorter than lower tooth. Mesoscutum with or without a median longitudinal groove on the median lobe. ……………………………………………………… 2 2. Median part of face relatively strongly convex. Area superomedia longitudinally elongate ( Fig. 65F ). Vein 2rsm indistinct or absent ( Fig. 20C ). Mesoscutum without a median longitudinal groove on the median lobe in Japanese species. ……………………………… Chirotica Förster, 1869 -. Median part of face relatively weakly convex or flat. Area superomedia not longitudinally elongate ( Figs 65G–J ). Vein 2rs-m short but distinct (e.g., Fig. 21C ). Mesoscutum with a median longitudinal groove on the median lobe in Japanese species. ………….....…………… Paraphylax Förster, 1869
