Isotrichothrips Priesner

(Figs 16, 76)

Isotrichothrips Priesner, 1968: 282 . Type species: Liothrips longirostris Karny, by original designation.

The two species included in this genus are from Java, Indonesia, and type specimens of longirostris have been examined. The genus belongs to the Liothrips -lineage, but is distinguished from the worldwide Liothrips because in males setae S1 and S2 on tergite IX are equally long. This condition also occurs in the New World genus Pseudophilothrips (Mound et al. 2010), from which Isotrichothrips is distinguished by the much shorter antennae (Fig. 16).

Diagnosis: Head longer than wide (Fig. 76); postocular setae well-developed; stylets retracted into head; antennae 8-segmented (Fig. 16), segment VIII shorter than VII, III with 1 sensorium, IV with 3; pronotum with 5 pairs of well-developed setae, notopleural sutures incomplete; basantra absent; mesopresternum transverse?; sternopleural sutures?; fore tarsal tooth absent in both sexes; fore wings parallel-sided, with duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides; male tergite IX with setae S2 as long as S1.
