Microtachycines tamdaonensis Gorochov & Storozhenko, 1992: 29 .

Material examined

Holotype VIETNAM • ♂; Vinh Phuc Province, Tamdao ; 9–18 Nov. 1990; A.V. Gorochov leg.; ZIN. Paratype VIETNAM • 1 ♀; same collection data as for holotype; ZIN .

Distribution

Vietnam (Tamdao).

Remarks

We examined the type specimens of Microtachycines tamdaonensis in ZIN and discussed with Dr A.V. Gorochov. We are sure that the male tenth abdominal tergite has a large outgrowth in the middle and the male epiproct is semicircular. Moreover, we examined the type specimens of M. elongatus and M. trispinosus in SEMCAS. All abdominal tergites of the two species have no outgrowths, but they have an extended epiproct. Therefore, we establish a new genus, Megatachycines gen. nov., and transfer M. elongatus and M. trispinosus to it.
