Proclitus ganicus Sheng & Sun, 2013 (A–C: KPM-NK 81127, female) ― A: lateral habitus; B: head, frontal view; C: head, mesosoma, and metasoma, dorsal view. Distribution . Japan (Honshu, Shikoku, Yakushima Is., Amamioshima Is., Tokunoshima Is., Okinawajima Is., Ishigakijima Is., Iriomotejima Is. and Yonagunijima Is.) and China . Bionomics . Host is unknown. In Japan , adults are collected in broadleaf forests and can be collected in winter. Remarks . In Eastern Palearctic species of this genus, this species is unique in several character states. Namely, the coxae black (largely yellow in other species), the hind tibia with conspicuous basal and apical black bands (usually indistinct or weak in other species), and the ovipositor sheath distinctly shorter than hind tibia (usually longer than hind tibia in other species).
