The male genitalia of seven species from the genus Aegosoma are described and compared. The result shows that 16 genital characters, such as narrow position of the apex of parameres, ratio of length and width of parameres, curvature of tegmen, ratio of spiculum gastrale and spiculum relictum, ratio of penis and tegmen, ratio of median structs and median lobe, curvature of penis, ratio of tegmen and parameres etc., can be used to identify species of Aegosoma. A key to Chinese species of Aegosoma is presented.展开更多
