(T.) laqueatus (Marsham, 1802) in the structure of the parameres and abdominal sternite VII. Te main character in the structure of the aedeagus of O. altaicus, which difer this species from O. laqueatus, is the form of the parameres, which is especially obvious seen in the lateral view. In O. laqueatus, depression between paired teeth on the posterior margin of sternite VII is rounded; in O. altaicus this depression forms obtuse angle. Illustrations of some morphological details of O. laqueatus are also presented: habitus, the aedeagus, the structure of the parameres and male abdominal sternite VII.
