This species seems to prefer deciduous forest habitats such as tropical dry forest, gallery forest, spiny forest or thicket, and transitional forest, but is much rarer in humid habitats at lower altitudes. Collections have been taken from sifted litter (leaf mold, rotten wood), under stones, on low vegetation, ex soil, ground forager(s), and ground nest using methods including sampling transects, soil sampling, sardine and tuna fish baiting and Malaise traps.

Identification

Rasoamanana and Fisher (2022) - A member of the Camponotus repens species group. Integument shiny black; standing pilosity sparse elsewhere; clypeus with short, rounded lobe; mesonotal suture impressed; petiole nodiform; gaster longer than mesosoma.

Camponotus tsimelahy may be confused with Camponotus repens and Camponotus ihazofotsy; all three species share the same sculpturation, form of petiole, and type of suberect setae. However, in profile, the dorsal outline of the mesosoma presents a slightly concave metanotal groove. See the discussion section under C. ihazofotsy.

Description

Morphological measurements: see Appendix 1 and Ratios of morphometric data for majors and minors

Minor

Medium-sized species. Absolute cephalic size (CS: 0.79±0.04; 0.77–0.81). In full-face view, head ovate, usually somewhat longer than broad, lateral margin of head straight and tapering to front (CWb/CL: 0.29±0.02, 0.28–0.29). Eyes subelliptical, protruding, their borders smoothly aligned to lateral margins of head (PoOC/CL: 0.09±0.00, 0.08–0.09). Mandibles triangular with six teeth. Anterior clypeal margin not produced, entire, broadly rounded. Antennal scape long, surpassing the occiput by the length of two basal funiculi (SL/CS: 0.41±0.03, 0.40–0.42). In lateral view, mesosoma without anterolateral margination, promesonotum distinctly convex, mesopropodeal suture deeply impressed so that propodeal dorsum raised to the level of mesopropodeal suture, propodeum angular in profile, with unequal basal and declivitous faces, the former horizontal, the latter straight to evenly concave (MW/ML: 0.19±0.02, 0.17–0.20; MPH/ML: 0.13±0.01, 0.13–0.14). In lateral view, petiole cuneate with convex anterior face and flat dorsal face. Body finely imbricate. Hairs whitish, one pair present on vertex, middle of mesonotum, and propodeum dorsum; two pairs on each side of lateral corner of propodeum; three pairs on lateral margins of petiole. Head and mesosoma reddish, legs light brown, basal face of first gastral segment light brown and the remaining segment dark brown to black.
