Cerceris chimoio DOLLFUSS nov.sp. ( Fig. 4 )

H o l o t y p e: ♀, Mozambique, 40 km SW Chimoio, 19°23'S 33°11'E, 650 m, 16.VII.2005, leg. J. Halada (ÖOLM). P a r a t y p e s: 2♀ ♀ same data as holotype (JHC, CAS).

E t y m o l o g y: The holotype of Cerceris chimoio was collected in Chimoio, Mozambique. R e c o g n i t i o n: The female of Cerceris chimoio is characterized by having the coxa III without longitudinal carina, the apical margin of clypeus with five teeth slightly erected ( Fig. 4a ), the mandible with double tooth internally and the mesopleuron with small tubercle. Additionally, the propodeal enclosure has transverse or slightly obliquely rugae, the scutum is shining and densely longitudinally elongate punctured and the legs are yellow and ferruginous. The female of C. saveensis is similar to C. chimoio but differs in having the anterior margin of the clupeus triangularly nearly rectangularly erected, this elevation has two carinae in ventral view which converge ventrally and is larger (11.5- 12.5 mm) ( C. chimoio 9-10 mm).

D e s c r i p t i o n: ♀, 9-10 mm. Sculpture: anterior margin of clypeus with five blunt teeth only slightly erected ( Fig. 4a,b ); lateral clypeal area distinctly emarginated; clypeus broader than long; mandible with double tooth internally; interantennal carina broad; prosternum without transverse carina; mesopleuron with small tubercle; epimeron without crest; propodeal enclosure with transverse or slightly oblique rugae and with medio-longitudinal furrow; petiolus wider than long ( Fig. 4e ); coxa III without longitudinal carina; sternum II without basal plate; pygidial plate ( Fig. 4d ); flagellum ( Fig. 4c ). Puncturation: clypeus and frons micropunctate and densely punctate; vertex densely punctate; propodeal collar densely punctate; prosternum micropunctate; scutum shining and densely longitudinally elongate punctate; metanotum impunctate; tegula impunctate; propodeal sides densely punctate; terga densely punctate; pygidial plate irregularly structured; sterna medial finely sparsely punctate, lateral coarsely punctate. Pilosity: latero-clypeal area with short appressed setae; rest of body with short erect setae. Coloration: black; following parts yellow: clypeus, frons, interantennal carina, mandible basal half, genae, pronotal collar, tegula partly, mesopleuron partly, epimeron, scutellum, metanotum, propodeal sides, terga partly and legs partly; following parts ferruginous: flagellum, vertex partly, tegulae partly, terga partly, pygidial plate, sterna, legs partly; wings hyaline, apical fuscous.
