Meiothrips Priesner

Remarks.

Dang and Qiao (2012b) provided a key to the five known species of Meiothrips , of which three are recorded from China: Meiothrips fuscicrus , Meiothrips menoni and Meiothrips nepalensis . Moreover, Meiothrips baishanzuensis Duan & Li from Henan Province was synonymised with Bactrothrips brevitubus Takahashi by Dang and Qiao (2012a).
