Abstract(cid:1) The presentpaper dealswitha newly recorded genusTurnixacarus Gaudet Atyeo, 1996and a newspecies, Turnixacarus
longisetus sp. nov. collectedfromTurnixsuscitator blakistoni (Swinhoe) (Gruiformes, Turnicidae) in Guizhou Province ofChina. The
type specimens of the newspeciesarepreservedinthe Insect Collectionof Southwest University, Chongqing, China.
