Remarks.
Dianous aerator
is extremely similar to
D. ruginosus
in appearance and both of them can be collected from same localities in Emeishan. The differences between the males are distinct, and the males may be identified by the shape of sternite VII, without dissection. However, there is no difference between the females, and thus the female specimens from Emeishan, Xianfeng Temple are not included in the species. The species is new to
Guizhou
.
