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).

Material examined. CHINA, Yunnan Prov. (Xishuangbanna District), 4 females 2 males on dried-up tree leaves, 7.x.2010, M.Y. Lin; Hainan Prov. (Xinglong County), 3 males on withered leaves, 16.iv.1963, B.L. Zhang. Distribution. China (Yunnan, Hainan); Japan.
