Fig. 39

Diagnosis

The species is distinctive in the shape of the body, unlike an ant, with a very convex cephalic part of the carapace ( Fig. 39B ). Legs relatively shorter than those in its congeners, a characteristic colouration of the abdomen, generally light with brownish grey patches on the sides.

Etymology

The specific epithet is a noun in apposition. It is Latin, meaning ‘helmet’, referring to the shape of the carapace.
