Thrips fumosus (Trybom)

Physopus fumosus Trybom, 1908: 3

Described from many specimens of both sexes from Mt Meru, Tanzania, specimens have also been seen from Rwanda. Faure (1962) re-examined the type series and noted that the chaetotaxy of the first vein of the forewing is highly variable. The species is remarkably similar to T. fumosoides in many details.

Diagnosis. Large dark brown species, with dark forewings including clavus; mid and hind tibiae brown, tarsi yellow; antennal segment III brown with extreme base yellow. Antennae 8-segmented. Head relatively long, ocellar setae III small on anterior margins of triangle; postocular setae II and IV minute. Pronotum medially with widely spaced transverse lines; midlateral setae long, posteroangular setae about 0.7 of pronotal length. Metanotum reticulate, almost equiangular but reticles with no internal markings; median setae long near anterior margin; campaniform sensilla present. Forewing first vein with setae on distal half varying from 7 to 12 (usually 8 or 9). Abdominal tergite II with four lateral marginal setae; VIII with complete fine but short comb; sternites with about 10 long discal setae, pleurotergites without discal setae.
