Crematogaster

ix. Crematogaster inflata- group

1. Members either with propodeum greatly inflated ( Fig. 36 ), or posterolateral denticles on the mesonotum ( Fig. 37 ).

2. Head large and broad, often medially depressed.

3. Petiole elongate-rectangular ( Fig. 20 ), oval ( Fig. 19 a) or circular ( Fig. 21 a).

4. Postpetiole of globular shape ( Figs 21 b, 24, 25), a faint posterior impression may be present.

This group most likely includes members of the former subgenera Physocrema and Paracrema (as listed by Bolton, 2011), as well as probably a number of species that have previously been associated with the subgenus Crematogaster sensu stricto. Definitive membership of species is, however, difficult to assess at this point and only certain for the following: C. subcircularis Mayr , C. inflata Smith , C. onusta Stitz , C. ampullaris Smith and C. modiglianii Emery.
