Thrips acaciae Trybom 

Thrips acaciae Trybom, 1910: 161 

Thrips kikuyuensis Trybom, 1912: 6  syn.n. Thrips spadix Hood, 1932: 131  syn.n. Thrips hirtiventris Hood, 1932: 126 

This is here interpreted as a widespread and variable species. Faure (1964) recognised that T. hirtiventris  from Tanzania was a synonym. Trybom (1912) did not compare T. kikuyuensis  from Kenya with T. acaciae  that he had described previously (1910) from Namibia (Kalahari). However, a cotype of kikuyuensis  has been examined and these two cannot be distinguished satisfactorily. One paratype female of T. spadix  has been studied, and this is also considered to be a synonym, despite Hood indicating that the third antennal segment was rather longer. As discussed below, quadridentatus  is possibly a further synonym of acaciae  . Material recognisable as T. acaciae  has been studied from Sudan, Kenya, Tanzania, Zululand, Namibia and Cameroon.

Diagnosis. Body and legs brown, tarsi and fore tibiae yellow; antennal segments I –II brown, III mainly yellow, IV –V yellow at base; forewing shaded with small white oval near base. Antennae 7 -segmented. Ocellar setae III arising outside triangle ( Fig. 1View FIGURES 1 – 12), shorter than distance between hind ocelli. Pronotum with many transverse sculpture lines not closely spaced, about 40 discal setae; posteroangular setae about 0.3 as long as pronotum; with 4 or 5 pairs of posteromarginal setae. Mesonotal anteromedian campaniform sensilla present. Metanotum medially with longitudinal row of large slightly elongate reticles ( Fig. 2View FIGURES 1 – 12), median setae near but not at anterior margin, campaniform sensilla present or absent. Forewing first vein with 2–4 setae on distal half; clavus with 5–8 marginal setae and 1 discal seta ( Fig. 2View FIGURES 1 – 12). Abdominal tergites with sculpture lines extending to setae S 1; VIII posterior margin with weak but complete comb; pleurotergites with no discal setae, but with weakly dentate or slender microtrichia on widely spaced lines of reticulation ( Fig. 3View FIGURES 1 – 12); sternites III –VII with more than 24 short discal setae in two irregular rows.
