Bactrothrips pictipes Haga & Okajima, 1989: 15–18 .

This species was described from the warm temperate zone of Japan and subtropical Ryukyu Islands based on a good number of females and males collected from dead leafy branches of Quercus and Castanopsis trees. Subsequently, it had been recorded from Taiwan ( Okajima 2006) and China ( Dang & Qiao 2012), and is newly recorded here from Vietnam. Although the specimens from Japan and Taiwan, including type-series, have the femora largely dark brown with apices yellowish, the specimens from Vietnam have the femora entirely dark brown. However, most of other structures are indistinguishable. This species has a pair of lateral red spots on each abdominal segment ( Fig. 2 ).

Although B. brevitubus zhamanus was treated as a synonym of B. pictipes by Dang and Qiao (2012) without sufficient scientific evidence or explanation, it is newly synonymized here with B. luteus . This is discussed above under luteus .
