Pristomerus khoikhoi sp. nov. urn:lsid:zoobank.org:act: C10B9AAB-BA87-4421-81A6-DE6331803CF9 Fig. 16 Diagnosis Small; mostly black with legs mostly yellowish-orange; face moderately punctate; clypeus transverse, ventrally smooth; remainder of head coriaceous to finely granulate; inner margins of eyes subparallel; malar line very long; antenna short and slender with 19–25 flagellomeres, penultimate flagellomere strongly elongate; mesosoma laterally moderately to densely punctate with speculum ventrally smooth, mesoscutum coriaceous with notaulus punctate, scutellum smooth; female femoral tooth small; ovipositor moderately long, strongly sinuous apically. Male with ocelli weakly enlarged, hind femur swollen and femoral tooth stronger. Differential diagnosis Small and mostly black, apparently restricted to the south of South Africa. Differentiated from all other species of Pristomerus by the combination of the coriaceous mesoscutum, the smooth scutellum, the short antenna and the very long malar line.
