Crematogaster scutellaris, copyright Philippe Garcelon.

Belongs within: Meranoplini.

Crematogaster is a pantropical genus of ants characterised by a heart-shaped gaster with the postpetiole attached to its upper surface; the petiole is flattened and the postpetiole is often bilobed in dorsal view (Heterick 2009). Though the genus as a whole is readily recognised, subordinate taxa are less so: species are often very variable and though several subgenera have been recognised, they are poorly defined and often of doubtful validity.
