Crematogaster brevis group

Polymorphism unknown ( C. treubi group is monomorphic). The occipital carina developed as distinct ridge (Fig. 2 a). Pronotal shoulders developed as ridges (Fig. 4). The petiole in dorsal view rectangular, with angular anterolateral corners (Fig. 3 a). Postpetiole bilobed behind. Mesosoma with standing hairs sparse.

This species group seems to be most similar to the Malagasy Mesocrema species, C. rasoherinae .
