R e c o g n i t i o n The male of Cerceris wachileensis has no longitudinal carina on coxa III, the petiole is ferruginous and the flagellomeres are wider than long ( Fig. 24c View Figs 24 ), the mandible has a distinct tooth internally, the apical margin is tridentate ( Fig. 24a View Figs 24 ), the median area of clypeus is flat in lateral view, the flagellomeres VI-XI have flat tyloidea, the propodeal enclosure is shiny and coarsely transversely rugose without a medio-longitudinal furrow, the lateral carina of pronotum is ending in a point, the scutum is distinctly longitudinally rugose and coarsely punctate on posterior half, sternum VI is rounded apico-lateral.

The male of C. tsavoensis DOLLFUSS differs from C. wachileensis by having the apical margin of the clypeus yellowish-brown, the clypeal brush is broad, the sternum VI has a triangular tooth latero-apical, the flagellomere XI is bent and the gonostyle is differently shaped. The male of C. saveensis DOLLFUSS differs from C. wachileensis by having the mandible with a rounded tooth internally, the scutum is shiny and densely coarsely punctate (at most posteriorly with short longitudinal rugae), the propodeal enclosure is obliquely rugose with distinct medio-longitudinal furrow, the flagellomeres IX-XI have tyloidea, the flagellomere XI is obliquely truncate and the genitalia are differently shaped. The male of C. diodonta SCHLETTERER differs from C. wachileensis by having the median area of the clypeus convex and dull, the latero-clypeal area has dense erect setae, the clypeal brush is broad with golden colour, the sternum VI has an acute tooth apico-lateral and behind it with a brush of yellow setae and the genitalia are differently shaped.

D e s c r i p t i o n: ♁, 9-10 mm. Sculpture: apical margin of clypeus tridentate ( Fig. 24a View Figs 24 ); mandible with tooth internally; flagellomeres VI-XI with flat tyloidea ( Fig. 24c View Figs 24 ); lateral carina ending in a point; prosternum without transverse carina; propodeal collar medially depressed; mesopleuron without tubercle; epimeron without crest; propodeal enclosure transversely rugose, without distinct medio-longitudinal furrow; petiole broader than long ( Fig. 24e View Figs 24 ); pygidial plate as in Fig. 24d View Figs 24 ; genitalia as in Figs 24f, g View Figs 24 ; sternum II without basal plate. Puncturation: median part of clypeus and frons punctate; clypeal side dull; vertex densely reticulate-punctate; pronotal collar punctate; tegula impunctate; scutum densely reticulate-punctate, posterior half more longitudinal rugose-punctate; scutellum and propodeal side densely reticulate-punctate; metanotum finely punctate; terga densely punctate; pygidial plate punctate; sterna II-IV apically punctate; sterna VI and VII dull. Pilosity: clypeal side and frons lateral covered with short erect setae; rest of body irregularly covered with erect setae. Colouration: black; following parts yellow: clypeus, frons, inter-antennal carina, scape, spot on pronotal collar, tegula partly, metanotum, terga II-VI apical, sterna II-V apico-lateral and legs; following parts ferruginous: petiole, tergum II latero-basal, pygidial plate apical; wings hyaline, apically fuscous.
