Synonyms

Camponotus cemeryi occurs in dry forest and spiny forest of west Madagascar and in the savannah shrubland and woodland of the central plateau (Fig. 49D). Along its distribution, members of the species can also be found in gallery forest habitats and in transitional forest between dry and humid forests. It may also establish colonies in human-modified habitats on the high plateau. Specimens have been collected mostly foraging on the forest floor and rarely on lower vegetation. The species nests in rotten logs, in the ground, under stones, and in rotting tree stumps. (Rakotonirina & Fisher, 2022)

Identification

With head in full-face view, lateral cephalic margins anterior to eye level parallel and lacking erect hairs, lateral and anteromedian clypeal margin continuously forming broad convexity; scape covered with erect hairs; mesosoma short and high (MPH/ML: 0.39, 0.46); petiolar node flattened anteroposteriorly; body color yellowish to brown.

Members of C. cemeryi can be separated from similar species like Camponotus boivini by the strongly convex dorsal outline of its short and high mesosoma. It can be differentiated from [[Camponotus mahafaly] by the presence of erect to suberect hairs on the antennal scape.

Worker specimens that show the typical form of C. cemeryi are generally found across the western dry forest of Madagascar, but specimens have been collected from the mountaintops on the high plateau of the island that present morphological variation in which the lateral margin of head posterior to eye level is covered with erect hairs, three pairs of erect hairs are present on posterior cephalic margin, and body color is generally depigmented yellow or brown with depigmented yellow in some parts of the body. Based on these characters, this variant may constitute a separate species; however, the dendrogram based on quantitative morphological analysis did not support this hypothesis.
