Median portion of clypeus lacking flange [C. kelleri Forel, 1891, CASENT0466090]. B. Propodeal spines absent; mesonotum (m) greatly raised with respect to pronotum and propodeum [C. tsisitsilo Blaimer, 2013, CASENT0120279]. C. Posterior face of mesonotum (pfm) long; promesonotal suture absent [C. kelleri, CASENT0466090]. D. Promesonotum forming a straight plane, posterior face of mesonotum (pfm) abruptly sloping into metanotal groove, propodeal spines situated high on propodeum (pd) [C. kelleri, CASENT0466090]. E. Pronotum dorsally with distinct median longitudinal groove [C.mafybe sp. nov., CASENT0317762]. F. Pronotum dorsally without median longitudinal groove [C. lobata Emery, 1895, CASENT0125498]. G.
