Bactrothrips flectoventris Haga & Okajima, 1989: 8.

Described originally from Japan, with paratypes from China (Taiwan), this species is unique in the genus in having the eyes prolonged posteriorly on the ventral surface of head. The specimens listed below were identified from the original description, but differ in the lengths of major setae on the head from the lengths in the original description (in parentheses): interocellar setae 106–152 (cf 65–125), postocellars 54–73 (cf 21–63), postocular cheek setae 50–62, postoculars 67–85 (cf 27–32), mid-dorsal setae 98–111 (cf 50–75). The major setae on the head are clearly longer than in the original specimens, and although the length of the postocular cheek setae was not given, the original illustration showed that the postocular cheek setae were much longer than the postoculars. This species presumably varies in some characters between different geographical populations. It is here recorded for the first time from the Chinese mainland (Hainan).
