Body yellow, but with brown markings laterally and on abdominal segment I; antennal segments I–III & V yellow, IV & VI brown in apical half, VII–VIII brown; fore wings mainly pale but with brown areas sub-basally and medially. Head reticulate, constricted to basal neck; only two pairs of ocellar setae. Antennae 8-segmented, III & IV with long, forked sense cones. Pronotum with few irregular lines of sculpture; one pair of short and conspicuous posteroangular setae. Mesothoracic spinula short; metathoracic spinula absent. Metanotum irregularly reticulate; campaniform sensilla present; two pairs of long setae, median pair stout and arising slightly behind anterior margin. Fore wing first and second veins with setal rows incomplete. Abdominal tergites II–VIII with numerous stout and irregularly arranged microtrichia on lateral thirds; II–V with pair of short and wide apart median setae; VI–VIII with one or two pairs of long setae medially; craspedum on VIII toothed laterally; X with complete longitudinal division. Sternites without discal setae, with three pairs of long marginal setae. Female macropterous or micropterous, males always micropterous.
Male sternites IV–VII with small transverse pore plate on antecostal ridge; tergite IX with pair of stout thorn-like setae arising from a large median tubercle.
Intraspecific variation
The colour of the thorax and abdominal tergite I show variation (Kudo 1977).
Genus and similar species information
This Old World genus comprises five species and possibly is related to the Oriental genera Indusiothrips and Isunidothrips (Mound & Marullo 1996). The lateral thirds of abdominal tergites of Dendrothripoides species exhibit many stout, dentate microtrichia, and the pronotum bears one pair of posteroangular setae. D. innoxius is the only species of this genus reported from the Americas.
World distribution
Described from Indonesia, it is now widespread in the Oriental and Pacific regions. It is also recorded from Central and South America.
