Scirtothrips spinosus Faure, 1929: 16

Described from 11 females and four males, taken in Transvaal and Cape Province, this species is remarkable among Scirtothrips species for having two pairs of unusually long setae on the posterior margin of the pronotum.

Diagnosis. Body mainly yellow, terga and sterna without median dark area but antecostal ridges dark; antennal segments II–VIII light brown; fore wing including clavus weakly shaded but extreme apex of wing pale. Ocellar setae III anterior to tangent between anterior margins of posterior ocelli (Fig. 21); pronotum striate but striae less closely spaced than aurantii, posteromarginal setae S2 and S3 about 0.7 times as long as pronotum (Fig. 21); fore wing second vein with 3–4 setae, distal posterior cilia straight but those at middle of wing wavy; metanotum with large elongate reticles medially (Fig. 21); terga V–VII with 4 discal setae on each lateral microtrichial field, VIII– IX with no microtrichia medially; sterna without microtrichia medially.
