Distribution. China ( Taiwan); “East Indies”, Nepal, Malaysia, Indonesia, New Guinea. Remarks. The syntypes are missing (per. comm. with Dr. Arnaldo Bordoni, Dr. Jiri Janak, and Dr. Aleksey Gusakov). However, the characters of the aedeagus and male genital segments ( Fig. 8 , cf. Jiri’s drafted drawing on a male syntype) could be easily recognized as different from congeneric species.
