E t y m o l o g y: The male of Cerceris pseudoanubis is similar to the male of C. anubis .

R e c o g n i t i o n: The male of Cerceris pseudoanubis is characterized in having the coxa III without a longitudinal carina, the scutum is shining and irregularly sparsely punctated (punctures 1-2 diampeters apart), the sternum II has a more or less developed longitudinal carina and the propodeal enclosure is shining with distinct medio-longitudinal furrow and more or less developed shallow oblique striae lateral. Additionally, the median area of clypeus is produced, shallowly tridentate and the lateral sides are emarginate ( Fig. 16a ), the mandible has a distinct tooth internally and the flagellomeres X and XI have tiny tyloidea (hardly to be seen) ( Fig. 16c ). The similar male of C. anubis differs from C. pseudoanubis by having the scutum densely punctate (punctures 0-0.5 diameters apart), the sternum II has no longitudinal carina and the flagellomeres IV-XI have small linear tyloidea. The male of bothavillensis is similar to C. pseudoanubis but differs by having the sternum II without a longitudinal carina, the scutum more densely punctate, the flagellomeres X and XI with short black linear tyloidea and the propodeal enclosure with distinct oblique rugae. The male of iniqua differs from C. pseudoanubis by a slightly lateral rised scutellum, the scutum is densely longitudinally punctate, the sternum II has no longitudinal carina, the propodeal enclosure has distinctly oblique rugae and the flagellum has no tyloidea. The male of C. tsavoensis differs from C. pseudoanubis by having the sternum II without longitudinal carina and the body is predominantly ferruginous.

D e s c r i p t i o n: ♁, 8-9 mm. Sculpture: apical margin of clypeus median produced and shallowly tridentate ( Fig. 16a ); clypeal sides emarginate; mandible distinctly dentate internally; prosternum with rounded blunt transverse carina; flagellomere XI nearly as long as X and slightly bent; flagellomeres X and XI with short yellow tyloidea (hardly to be seen) ( Fig. 16c ); mesopleuron without tubercle; epimeron without crest; propodeal enclosure shining, with distinct medio-longitudinal furrow and lateral with more or less distinct oblique rugae; petiolus slightly longer than wide ( Fig. 16e ); sternum II with more or less distinct longitudinal carina; coxa III without longitudinal carina; sternum VI with lamellar tooth apicao-lateral; pygidial plate ( Fig. 16d ); genitalia ( Fig. 16f ). Puncturation: clypeus and frons irregularly punctured; prosternum densely punctate; gena and vertex densely punctate; pronotal collar nearly impunctate; scutum shining and irregularly sparsely punctate (punctures 0-2 diameters apart); scutellum sparsely punctate; metanotum nearly impunctate; mesopleuron, propodeal sides and terga coarsely densely punctate; sterna apico-lateral punctate; pygidial plate irregularly punctate. Pilosity: clypeal brush long; body sparsely covered with erect setae. Coloration: black; following parts yellow: clypeus frons, gena, pronotum, tegula, mesopleuron, mesopleuron venter, scutellum, metanotum, propodeum lateral, terga and sterna predominantly, fore- and midleg, hindleg partly, mandibles (except apex); flagellum ferruginous; wings hyaline, apex fuscous.

♀ unknown.
