Diagnosis.

In full-face view, lateral margins of head anterior to eye level approximately parallel and covered with erect hairs; two apical teeth of mandible normally spaced; mesonotum short and lacking constriction; propodeal dorsum approximately straight, 2 × as long as declivity; dorsal margin of petiole shorter than posterior margin.

Description.

Minor worker. In full-face view, lateral margins of head anterior to eye level approximately parallel, rounding progressively towards a slightly concave posterior margin; eye convex and large (EL/CS: 0.27 ± 0.00; 0.27-0.28), not breaking lateral cephalic margin, location of its posterior margin at posterior 1/4 of head (PoOc/CL: 0.26 ± 0.00); frontal carinae parallel, not widely opened posteriorly (FR/CS: 0.27 ± 0.0); clypeus lacking anterolateral angle, anteromedian margin broadly convex; two apical teeth of mandible normally spaced; antennal scape relatively long (SL/CS: 1.62 ± 0.01; 1.61-1.63). Dorsal outline of mesosoma approximately evenly convex; metanotal groove visible; propodeal dorsum straight, ca. 2 × as long as declivity, joining it at a blunt angle. Petiole nodiform, its dorsal margin shorter than anteriorly inclined rear margin and joining the anterior margin at a blunt angle.

First and second gastral tergites without a pair of white spots; short erect hairs on lateral margin of head present; near posterior margin of head with two elongate erect hairs; antennal scape covered with erect hairs; junction of propodeal dorsum and declivity with one pair of erect hairs.

Major worker. Unknown.

Distribution and biology.

Camponotus joany is geographically restricted to the dry forest of Montagne de Francais in the north of Madagascar (Fig. 61D View Figure 61 ). Its nest sites are unknown and workers have been found foraging on lower vegetation.
