Biology

Castes

Ergatoid queen described by Alpert (1992).

No alate or dealate queens occur in any of the Malagasy Terataner species. Colonies are almost always monogynous with a single reproductive, an ergatoid queen, that differs only slightly from corresponding workers. This reproductive lacks both wings and ocelli, and has an almost normal, worker-like thorax. The ergatoid queen is externally distinguishable from workers only by very subtle characters (e.g., small spines or tubercles below the mesonotal groove; a unique pattern of rugae on the sides of the pronotum) that vary among species. Ergatoid queens have ovaries bearing two to three ovarioles.
