Both sexes fully winged. Body pale brown with red internal pigment; forewings pale at base and apex, with one dark and one rather paler transverse bands; antennae pale brown with segments IV–VI sometimes yellow at base; tarsi and apices of tibiae yellow. Head wider than long, finely reticulate between ocelli; ocellar setae pair III small but weakly spatulate, arising between anterior margins of posterior ocelli. Antennae 9-segmented; segments III–IV with forked sensorium, segment VI inner margin with long sensorium arising close to base. Pronotum with narrow transverse reticulation, faint markings between the main striae, discal setae weakly spatulate; posterior margin with three pairs of setae and one pair of posteroangular setae. Metanotum with closely spaced longitudinal striae, median pair of setae far distant from anterior margin. Forewing first vein with two widely spaced setae on distal half, second vein without setae; wing apex with one stout seta; cilia arise ventrally near anterior margin. Tergites with median pair of setae longer than distance between their bases; sculpture on lateral thirds with short longitudinal lines giving appearance of microtrichia; posterior margin of VIII with complete but weak comb; tergite X with no longitudinal split.
The genus Pseudodendrothrips includes 17 described species, but the significance of some of the species in which the body colour is mainly yellow remains conjectural. P. gillespiei is one of only two described species with the forewings banded, the other being from the Philippines (Mound & Tree, 2007).

Breeding on leaves
Collected originally from Alyxia ruscifolia, the true host is probably Trophis scandens (Moraceae)
