Asprothrips bimaculatus Michel & Ryckewaert

( Figs 1–2 , 21 )

Asprothrips bimaculatus: Michel & Ryckewaert 2014: 496 .

Female. Adequately described and illustrated by Michel & Ryckewaert (2014).

Male. Similar to female, but body paler; abdominal tergite VI without a pair of brown patches; sternites II–VII each with one small, rounded pore plate; genitalic paramere shape see Figure 21 .

Specimens examined. CHINA, Guangxi, Nanning City, Nalou Town (22°36'N, 108°39'E), 1 male, 1 female collected from Pennisetum purpureum (Poaceae) , 3.x.2012 (Shulan Yang). Taiwan, Pingdong, Kenting, Ngoluanpi Park (21°54' 09″N, 120°51'15″E), 1 female from grass ( Poaceae ), 5.viii.2012 (Xiaoli Tong).

Distribution: Martinique in the French West Indies, Malaysia (ThripsWiki 2015), China.

Comments. Unlike the type specimens of A. bimaculatus that have a pair of brown patches on abdominal tergite VI, the brown patches in the Chinese specimens are faded and only faintly visible. However, the male that is recorded here for the first time is devoid of such brown patches. With the description below of two new species from China, Asprothrips now includes seven described species that are all from Asia but with seminigricornis widespread in greenhouses of several countries ( Mound 1999, Sartiami & Mound 2013), and bimaculatus that shows a remarkable disjunct distribution between Martinique in the Caribbean and Asia ( Malaysia) (ThripsWiki 2015—identified by Ng Foo Yong). The new record of this species from China, including the male, supports the probability that it is originally from Asia, in common with the other members of the genus, and has been introduced to the western hemisphere.
