Asianthrips Okajima

( Figs 19 , 24 )

Asianthrips Okajima, 2006: 187 . Type species: Asianthrips orientalis Okajima , by monotypy.

The only species in this genus was described from southern Japan and Taiwan, and is almost unique among Phlaeothripinae in having the mesopresternum fused to the mesoeusternum medially with a reduced suture present laterally ( Fig. 24 ). According to Okajima (2006) this genus is probably related to Adraneothrips , although unlike the Asian members of that genus the notopleural sutures are complete.

Diagnosis: Head slightly longer than wide ( Fig. 19 ); eyes normal, postocular setae well-developed and wide apart; stylets retracted to postocular setae, usually wide apart; antennae 8-segmented, III with 3 sensoria, IV with 4; pronotum with 5 pairs of well-developed setae, notopleural sutures complete; basantra weakly present; mesopresternum fused to mesoeusternum medially ( Fig. 24 ); sternopleural sutures absent; fore tarsal tooth absent in both sexes; fore wings weakly constricted medially, with duplicated cilia; pelta nearly triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, shorter than head; male sternite VIII without pore plate.
