Phasmothrips Priesner

(Fig. 129)

Phasmothrips Priesner, 1933b: 82 . Type species: Phasmothrips asperatus Priesner, by monotypy.

Based on a single species, that is known only from the original series of both sexes, taken from a leaf gall on Sloanea in Java, this genus is considered to be a member of the Liothrips -lineage. However, it is remarkable for the numerous short-stout setae on the pronotum (Fig. 129) and fore femora, as well as on the head. In the absence of long pronotal setae it is unlike any species of Liothrips or related genera.

Diagnosis: Head longer than wide, cheeks with about 8 pairs of short, stout setae (Fig. 129); head dorsally with one pair of small tubercles on posterior quarter; eyes without enlarged ommatidia, postocular setae small, not reaching posterior margins of eyes; maxillary stylets one-third of head width apart, retracted into basal third of head; antennae 8-segmented, III with 1 sensorium, IV with 3; pronotum well-developed and rounded, only epimeral setae well-developed, other major setae small, about 8 pairs of stout spur-like setae on anterior angles, notopleural sutures complete; basantra absent; mesopresternum reduced medially; sternopleural sutures absent; fore tarsal tooth present in both sexes; fore wings parallel-sided, with about 90 duplicated cilia; pelta rounded triangular; tergites II–VII with 2 pairs of wing-retaining setae; lateral abdominal setae very long, tergite IX setae slightly longer than tube; tube with straight sides, slightly shorter than head; male sternite VIII with an entire pore plate.
