Holotype: J, KENYA, Eastern Katutu-Kithioko , 27.XI.1999, leg. M. Snižek ( JHC).

E t y m o l o g y:Inhonour of Mag. Esther Ockermüller, curator of the Entomological Collection of Biodiversitätszentrum Linz, Austria.

R e c o g n i t i o n:Themaleof Cerceris ockermuellerae has no longitudinal carina on coxa III, the flagellomeres III-X are distinctly broadened in lateral view and have distinct linear tyloidea ( Fig. 12c View Figs 12 ), the flagellum is dorsally black and ventrally ferruginous, the flagellomeres X and XI are all black, the apical margin of the clypeus is tridentate ( Fig. 12a View Figs 12 ); the sternum VI has a tiny acute spine apico-lateral and the propodeal enclosure is obliquely rugose with distinct medio-longitudinal furrow. Additionally, the sternum II has a shallow longitudinal carina, the mandible is edentate internally, the pronotal collar is rounded laterally and the scutum and the propodeal side are shiny and nearly densely punctate.

The male of C. pseudovittata DOLLFUSS has also broadened flagellomeres but differs from C. ockermuellerae by having the propodeal enclosure smooth as a mirror, nearly without lateral- and medio-longitudinal furrows, the propodeal side is smooth and irregularly sparsely punctate (punctures 0-5 diameters apart), and the pronotal collar is rectangularly raised laterally. The male of C. zeerustensis DOLLFUSS has broadened flagellomeres but the tyloidea are short, the sternum VI is rounded apically and the genitalia are differently shaped.

D e s c r i p t i o n:J, 9.5 mm. Sculpture: apical margin of clypeus tridentate ( Fig. 12a View Figs 12 ); flagellomeres III-X broadened in lateral view and with linear tyloidea ( Fig. 12c View Figs 12 ); mandible without distinct tooth internally; pronotal collar rounded lateral; prosternum without transverse carina; mesopleuron without tubercle; epimeron without crest; propodeal enclosure obliquely rugose, with distinct medio-longitudinal furrow; petiole slightly longer than wide; pygidial plate as in Fig. 12d View Figs 12 ; sternum II with shallow longitudinal carina; sternum VI with tiny acute tooth apico-laterally; genitalia as in Figs 12e, f View Figs 12 . Puncturation: median part of clypeus and frons punctate; clypeal side dull; vertex and pronotal collar densely punctate; scutum and scutellum nearly densely punctate; mesopleuron and propodeal side coarsely and densely punctate; terga densely punctate; pygidial plate densely punctate; sterna lateral punctate. Pilosity: clypeal side covered with short appressed setae; rest of body irregularly covered with sparse erect setae. Colouration: black; following parts yellow: clypeus, frons, inter-antennal carina, scape anterior half, pronotal collar lateral, tegula lateral half, metanotum, petiole apical, tergum II apico-lateral, tergum III broad band apical, terga V and VI apical, sternum II and III apico-lateral; legs yellow with black marks; flagellomeres I-IX dorsally black, ventrally ferruginous; flagellomeres X and XI all black; wings hyaline, apically fuscous.
