Liothrips heptapleurinus (Priesner)
(Figs 43–46)
Smerinthothrips heptapleurinus Priesner, 1935: 360–361 .
This species was collected by Takahashi at Taihoku, Taiwan, 23.xii.1926, from Heptapleurum (= Schefflera). Two syntypes were studied by Okajima (2006) who recorded this thrips from Japan, Ryukyu Islands, together with a full re-description. The following notes are based on that description.

Head about 1.5 times as long as wide (Fig. 43); po setae longer than eyes, narrowly blunt at apex; maxillary stylets retracted to level of po setae, rather close together. Pronotal am setae shorter than aa setae; mesopresternum connected medially (Fig. 44); metanotum sculptured with fine longitudinal striae or reticles; fore wing with 14–16 duplicated cilia. Pelta bell-shaped, with a pair of CPS (Fig. 45); tube conical, sides straight.
