Result shows that 18 genital morphologcial characteristics are different within this subfamily. Five differences such as shape of the parameres, ratio of length and width of parameres, shape of tergite VIII, etc., could be used to indentify tribes within the Spondylidinae. Six morphologcial characteristics, such as ratio of parameres and tegmen, shape of roof, curvature of median lobe, etc., could be used to identify genera within the tribe Asemini. Two characteristics, ratio of length and width of parameres and the setation of tergite VIII can be used to identify species in the genus Cephalallus. A key to the Chinese tribes of Spondylidinae and the genera of Asemini is presented.展开更多
