Female macroptera. Body mainly yellow with light brown markings, apex of tergite X brown; antennal segment I as pale as head, II–III shaded at least near apex, IV–VIII brown; fore wings pale with setae dark. Antennae 8-segmented, III–IV with short forked sensorium. Head wider than long; vertex, including ocellar triangle, with sculpture lines; 3 pairs of ocellar setae, pair III no longer than longitudinal diameter of an ocellus, arising between posterior margins of hind ocelli; 4 pairs of small postocular setae. Pronotum with transverse lines of sculpture, 2 pairs of long posteroangular setae; median posteromarginal setae slightly longer than remaining 3 pairs of posteromarginals. Mesonotal anterior campaniform sensilla present. Metanotum with sculpture irregular, forming elongate concentric area posteromedially; campaniform sensilla present; median setae at anterior margin. Mesofurca with spinula. Fore wing first and second veins with complete row of setae; clavus with 5–6 veinal and one discal setae. Tergites without craspeda; V–VII without ctenidia but with irregular microtrichia on lines of sculpture laterally; sculpture lines extend to median setae; VIII with paired ctenidia anterolateral to spiracle, posteromarginal comb of regular long microtrichia; tergite X long and slender, twice as long as IX. Sternites without discal setae; VII with setae S1 arising at margin.
Male macroptera. Similar to female but smaller; antennal segments I–II yellow in contrast to brown III–VIII; tergite VIII comb long and regular, median pair of setae on IX well-developed; sternites III–VII with small circular pore plate; sternite VIII posterior margin with several prominent microtrichia.
Species of the genus Pseudanaphothrips share many character states with species of Frankliniella, but none of them have tergal ctenidia so well-formed. Currently the genus includes nine species, all but one from Australia. However, some of these are based on very few specimens, and these remain particularly difficult to distinguish (Mound & Palmer, 1981). P. aureolus is readily distinguished by the elongate tenth abdominal segment in females, and the small circular sternal pore plates in males.
