E t y m o l o g y:The species is named after the town Karagwe in Tanzania where the holotype was collected.

R e c o g n i t i o n: The male of Cerceris karagwe has no longitudinal carina on coxa III, the sternum VIII has lateral-basal rounded projections ( Fig. 5d View Figs 5 ), the propodeal enclosure is obliquely rugose with a distinct developed medio-longitudinal furrow, flagellomeres V-XI have shallow tyloidea (hardly to be seen), the flagellomere XI is as long as X and slightly bent ( Fig. 5c View Figs 5 ), the scutum is shiny and densely longitudinally rugose-punctate, the mesopleuron and the propodeal side are coarsely reticulate-punctate. Additionally, the sternum II is without basal plate.

The male of C. koforidua DOLLFUSS differs from C. karagwe by having a different (normal) sternum VIII. The flagellomeres IX-XI have short tyloidea and the median part of the clypeus has in most specimens a transverse fuscous and impressed line slightly behind the apex. The male of C. bulawayoensis BRAUNS differs from C. karagwe by having a different (normal) shaped sternum VIII, the propodeal enclosure is densely punctate and the flagellomeres IX-XI are flattened below, XI is obliquely truncate and emarginate with an oblique carina.

D e s c r i p t i o n:J, 8-9 mm. Sculpture: apical margin of clypeus shallowly tridentate or straight ( Fig. 5a View Figs 5 ); mandible with shallow tooth internally; flagellomeres V-XI with shallow tyloidea (hardly to be seen); flagellum XI as long as X and slightly bent ( Fig. 5c View Figs 5 ); prosternum without transverse carina; mesopleuron without tubercle; epimeron without crest; propodeal enclosure obliquely coarsely rugose, medio-longitudinal furrow distinctly developed; petiole slightly longer than wide; pygidial plate longer than wide ( Fig. 5e View Figs 5 ); sternum VIII latero-basal with rounded projections ( Fig. 5d View Figs 5 ); genitalia as in Figs 5f, g View Figs 5 ; sternum II without medio-basal plate; sternum VI with more or less developed tooth apico-lateral. Puncturation: median part of clypeus and frons punctate; clypeal side micro-punctate; vertex coarsely punctate; prosternum impunctate; pronotal collar densely punctate; scutum and scutellum shiny, densely and coarsely longitudinally rugose-punctate; metanotum and tegula impunctate; mesopleuron and propodeal side shiny and coarsely reticulate-punctate; mesopleuron venter shiny and impunctate; terga densely coarsely punctate; pygidial plate densely punctate; sterna lateral punctate. Pilosity: clypeal side and frons covered with short appressed setae; gena, mesopleuron, propodeal side and petiole covered with erect setae; rest of body irregularly covered with erect setae. Colouration: black; following parts variably yellow: clypeus, frons, inter-antennal carina, pronotum partly, tegula partly, petiole apical, terga III-VI apical, sternum III lateral; legs black, yellow and ferruginous; wings hyaline, marginal cell of forewings fuscous.
