Distinguishing features

Female fully winged. Body and legs brown, tarsi yellow; fore wings dark at base, then with short pale area, then dark to apex; antennal segments III–V yellow, other segments brown. Head wider than long, reticulate between ocelli; ocellar setae pair III outside ocellar triangle in front of posterior ocelli. Antennae 8-segmented; segments III–IV with slender forked sense cone; segment VI inner margin with long sense cone arising on distal half. Pronotum transversely reticulate, reticles with internal markings, discal setae minute, posterior margin with no long setae. Metanotum with irregular longitudinal sculpture, median pair of setae far from anterior margin. Fore wing with no prominent setae, wing apex recurved with no stout seta, cilia arise ventrally far behind anterior margin. Tergites with median pair of setae longer than distance between their bases; lateral thirds of tergites with complex irregular sculpture; posterior margin of VIII with complete comb; tergite X with no longitudinal split.
Male not known.

Related species

D. willliamsi is similar to D. glynn in antennal structure, but has differently coloured fore wings, and different tergal sculpture. The Old World genus Dendrothrips currently includes 56 described species, mainly from Africa and Asia. The metathoric endofurca is greatly enlarged, "lyre-shaped", extending into the mesothorax, the sides of the metathorax are greatly swollen, the hind coxae are wider than long, the fore wing cilia arise ventrally well behind the anterior margin, and the apex of the fore wing is recurved without a prominent terminal seta. The form of the wing apex distinguishes the members of this genus from the other species placed in the Dendrothripinae.
