Description
Pristomerus san sp. nov.
urn:lsid:zoobank.org:act: 8ECF1D02-AFCA-4063-BEAF-6D479B1EB6F5
Fig. 33
DiagnosisRather small; yellowish-orange overall, with basal tergites sometimes variously infuscate; face and clypeus densely and deeply punctate but clypeus apically smoother, remainder of head coriaceous; clypeus transverse; malar line long; antenna short with 26–28 flagellomeres, penultimate flagellomere subquadrate; mesosoma entirely densely, deeply and evenly punctate, except almost entire pronotum and ventral half of speculum smooth; female femoral tooth absent; ovipositor moderately short, apically sinuous. 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 diagnosisModerately 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.
