Camponotus radamae

Endemic to Madagascar, Camponotus radamae normally occurs in eastern humid forests ranging from the littoral region to mountaintops (Fig. 70D). The species is arboreal and terrestrial, and nests in rotten logs, tree stumps, dead branches, twigs, and rot pockets above the ground, while its workers rarely forage on the ground and on lower vegetation.

Identification
Lateral cephalic margins approximately parallel in full-face view; two apical teeth of mandible closely spaced; lateral cephalic margin posterior to eye level without erect hairs; antennal scape covered with appressed hairs; mesosoma much higher and short, with propodeal dorsum 3 × as long as declivity; petiolar node more or less flattened anteroposteriorly and tapering dorsally.

Camponotus radamae is similar to Camponotus vano in that the two apical teeth of their mandible are closely spaced, but C. vano has a more elongate body in which the mesosoma is very low and long, and its propodeal dorsum is at least four times as long as the declivity surface. In C. radamae the propodeal dorsum is 3 × as long as the declivity.
