Camponotus ihazofotsy is known from the dry forest of Tsimanapetsotsa and Andohaela NP. We assume that this species is arboreal because all samples were collected from 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 ihazofotsy closely resembles Camponotus tsimelahy, although morphological examination reveals a number of distinguishing characters. The most interesting character is the form and length of the petiolar scale; in C. ihazofotsy the petiole is cuboidal (anterior and posterior face about the same height), while in C. tsimelahy the posterior face is higher than the anterior face. In addition, these two species are sympatric at one site, Ihazofotsy. Molecular phylogenetic analysis provides strong evidence that they represent separate lineages (unpublished data).

Description

Morphological measurements: see Appendix 1 and Ratios of morphometric data for majors and minors
Minor
Small-sized species. Absolute cephalic size (CS: 0.78±0.12; 0.75–0.81). In full-face view, head ovate, usually somewhat longer than broad, lateral margin of head straight and tapering to front (CWb/CL: 0.34±0.01, 0.34–0.35). Eye subelliptical, protruding, its border smoothly aligned to lateral margins of head (PoOC/CL: 0.09±0.03, 0.08–0.10). 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: 0.35±0.03, 0.34–0.36). In lateral view, mesosoma without anterolateral margination, promesonotum distinctly convex, mesopropodeal suture deeply impressed so that propodeum dorsum is 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: 0.18±0.01, 0.17–0.18; MPH/ML: 0.10±0.01, 0.10–0.10). In lateral view, petiole cuneate, its anterior face convex, its posterior face more flattened. 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.
