Bactrothrips quadrituberculatus (Bagnall)
(Figs 35, 41)
Idolothrips quadrituberculatus Bagnall, 1908: 210 .
Described originally as Idolothrips quadrituberculatus, the species was combined with Bactrothrips by Mound & Palmer (1983). The specimens listed below were identified using the detailed description in Haga & Okajima (1989) and Okajima (2006), and this is the first record of this species from China. It is very similar to B. brevitubus with large body and mid-dorsal setae of head the longest, but is distinguished in the key above by length of the postocellar setae. The genetic distance of COI averaged 0.064 (range=0.061–0.067).
