Bactrothrips brevitubus Takahashi, 1935: 61 .

Meiothrips baishanzuensis Duan & Li, 1995: 211 . Syn. n.

Described originally from Japan, this species is recorded widely in South China based on details given by Okajima (2006), and Meiothrips baishanzuensis Duan & Li is here considered a synonym based on examination of the holotype. Individuals are variable in morphology; in particular, the tubercles on abdominal segment VI are long in large males but short in small males ( Figs 38, 39 ). The COI results support the interpretation that this variation is intraspecific. The species is identified by the long postocellar setae (about 3–5 times as long as diameter of one postocellus, sometimes a little shorter than the longest mid-dorsal setae) and short epima (always shorter than one third of epim).
