Thrips gowdeyi (Bagnall)

Ceratothrips gowdeyi Bagnall, 1919: 254 Physothrips neavei Karny, 1925b: 129

Taeniothrips modestus Hood, 1925: 134 syn.n. Taeniothrips debilis Hood, 1925: 136

Physothrips gowdeyi Bagnall, 1926: 105

Taeniothrips umtali Moulton, 1930: 203 syn.n.

Type material of all of these nominal species has been examined. Ceratothrips gowdeyi and Physothrips gowdeyi both have the same collection data, “Flowers of Solanum , Kampala, Uganda, 11.xi.1917 ”, and the type specimen of Physothrips neavei was also from Kampala, in flowers of Ipomea hildebrantei , 26.xii.1920. The types of modestus came from Cameroon, of debilis from southern Nigeria, and of umtali from Zimbabwe. Specimens have also been studied from Kenya and South Africa. This widespread species is generally similar to T. acaciae , but has eight antennal segments, only three instead of four lateral marginal setae on tergite II, and fewer pronotal discal setae. The metanotal sculpture varies in detail ( Figs 15–18 ), particularly between large and small individuals.

Diagnosis. Body variably brown, abdomen sometimes paler, tibiae sometimes yellow; forewing weakly shaded, scarcely paler at base; antennal segment III largely yellow, remaining segments brown. Antennae 8- segmented. Ocellar setae III short, on or just outside ocellar triangle. Pronotum with irregular transverse lines; posteroangular setae about 0.3 as long as pronotum. Mesonotal anterior campaniform sensilla present. Metanotum with irregular longitudinal reticulation medially ( Figs 15–18 ), no campaniform sensilla, median setae close together not near anterior margin. Forewing first vein with 3 setae on distal half; clavus with 5 marginal setae. Tergite II with 3 lateral marginal setae; tergal sculpture lines scarcely reach campaniform sensilla; VIII with complete weak comb; sternites III–VII with 10 to 25 discal setae in two irregular rows; pleurotergites with microtrichia almost ciliate, no discal setae. Male yellow, sternites III–VII with transverse row of discal setae posterior to rather small oval pore plate.
