Syntypes : France , Spain . Brief description. Female: Body black with extensive yellow in all body parts ( Figs 5 A-D, 7A, B, 8A), flagellum black above and red beneath; tegula yellow; legs mainly yellow with black spots on coxae, trochanters and femora; wings hyaline, slightly infumate apically, with pale brownish veins ( Fig. 5A ); pygidial plate dark reddish brown ( Fig. 8C ). Clypeus with middle lobe convex, preapical area of clypeus with two small processes, hardly seen from punctures, free margin with two small lateral teeth surrounding minute ones in the middle (sometimes hardly seen from punctures) ( Figs 5C , 8A ); propodeal enclosure longitudinally striated either throughout or at base, parts adjacent to propodeal enclosure with dense coarse, very close punctures ( Figs 5B , 8B ); hindcoxa with sharp keel along inner margin; pygidial plate relatively long, oval, rugose with some sparse punctures at base, broad at base, gradually narrowed towards apex, apex narrowly rounded, with dense inwardly curved whitish setae along whole outer edge ( Fig. 8C ); gastral S 5 denticulate at apex, with two large middle teeth with a rounded depth in between, followed laterally by a number of small teeth ( Fig. 8D ). Male ( Fig. 7C ): Body with reduced yellow compared to female, scutellum entirely black; clypeus with apicomedian protrusion; propodeal enclosure longitudinally ridged at base, smooth and shiny posteriorly; pygidial plate sub-rectangular, parallel-sided, straight posteriorly. Material examined: Bulgaria ( Photo from CAS ): 1♀ , 1♂ , Sandansky , 31.viii.1956 , W.J. Pulawski collector ( CAS ); 1♀ , Wadi El Lega ( South Sinai ), 4.xi.1943 ( EFC ) . Distribution: PA: Afghanistan , Algeria , Armenia , Bulgaria , China , Croatia , Egypt , France , Hungary , Iran , Iraq , Israel / Palestine , Italy , Jordan , Kazakhstan , Kyrgyzstan , Libya , Mongolia , Montenegro , Morocco , Portugal , Romania , Russia , Slovenia , Spain , Syria , Tajikistan , Tunisia , Turkey , Turkmenistan , Ukraine , Uzbekistan . Intraspecific variation: In some Russian specimens, the yellow of the body is replaced by more or less whitish yellow ( Schmidt 2000 ). In the Egyptian specimens, propodeal enclosure is longitudinally ridged at basal half, smooth and shiny on posterior half ( Fig. 5B ); in European species, propodeal enclosure is longitudinally ridged all over ( Fig. 8B ). In Egyptian specimens, propodeum has two large yellow markings laterally ( Fig. 5B ), while in European specimens, propodeum is entirely black ( Fig. 8B ). Comments . Roche (2007a) listed C. bupresticida libyca de Beaumont, 1960 in Egypt , without mentioning any supporting data, this may have been collected from Siwa Oasis which is located east of Egypt-Libya border. He synonymized C. bupresticida Dufour with C. bupresticida libyca . On examining the female specimen collected from Wadi El-Lega (S. Sinai ) agrees very well with all the characters of the nominate C. bupresticida . It differs from C. odontophora in the following: body with extensive yellow (in C. odontophora pale colour of body (ivory) is distinctly reduced); propodeal enclosure ridged throughout or at least at basal half (in C. odontophora propodeal enclosure is smooth and shiny); female S 5 with two median large teeth, separated by deep, rounded emargination ( Fig. 8D ) (in C. odontophora the two median teeth are distinctly smaller, with slight emargination in between ( Fig. 15B )); pygidial plate wrinkled, with some scattered punctures ( Fig. 8C ) (in C. odontophora pygidial plate is impunctate, with few fine, whitish setae at base ( Fig. 15A ).
