Male with ocelli, hind femur and femoral tooth enlarged, inner margins of eyes diverging ventrally, and area superomedia more slender; otherwise similar to female. Differential diagnosis Moderately sized and yellowish orange with no defined dorsal dark markings; differentiated from all other Afrotropical species by the combination of the long malar line, the almost smooth pronotum, the deep and dense punctation, the absence of a femoral tooth in females and the rather short ovipositor. Morphologically close to P. moramora and related species which are also present in Southern Africa, but the longer malar line, the smooth pronotum and the deep dense punctation of P. san sp. nov. are reliable identification cues.
