Fig. 4. Key to subgenera & species-groups of Malagasy Crematogaster (part II); key to the species of the C. degeeri-assemblage (part I). A. Median portion of clypeus lacking flange C. kelleri. B. Propodeal spines absent; mesonotum (m) greatly raised with respect to pronotum and propodeum C. tsisitsilo. C. Posterior face of mesonotum (pfm) long; promesonotal suture absent C. kelleri. 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. E. Pronotum dorsally with distinct median longitudinal groove C. mafybe. F. Pronotum dorsally without median longitudinal groove C. lobata. G.
