Explanation of Names

Misspelling of Greek kremastos 'hanging', 'suspended' + gaster 'stomach' (refers to the dorsal attachment of postpetiole to gaster)
workers and males 2.5-3.5mm, queens about twice as long.
The unusual heart-shaped gaster (as viewed from above) and dorsal articulation of the postpetiole to the gaster are distinguishing features of this genus.
Northern and desert species soil-inhabiting, most species of the warm, humid Southeast arboreal or semi-arboreal.
Honeydew, extrafloral nectar, scavenged protein from bird and other droppings, carrion.
