The known elevational range of Camponotus jjacquia extends from 43 to 923 m. Specimens have been collected on tree trunks, on low vegetation, in leaf litter, and under stones in Bismarckia woodland, deciduous forest, gallery forest, savannah woodland, spiny forest, and tropical dry forest. This species nests in the soil.
Identification
Rasoamanana and Fisher (2022) - A member of the Camponotus repens species group. Integument black; entire body with plentiful, erect setae; anterior clypeal margin produced into a rounded triangular lobe; dorsal outline of mesosoma slightly impressed at the level of metanotum; petiole long and low.
The unique petiolar shape, the density of its pilosity, and the shape of its metanotal dorsum make C. jjacquia a very distinctive species.

Description
Worker
Morphological measurements: see Appendix 1 and Ratios of morphometric data for majors and minors
Minor
Medium-sized. Absolute cephalic size (CS: 0.99±0.14; 0.91–1.09). In full-face view, head almost quadrate (CWb/CL: 0.32 ± 0.02; 0.31–0.34); posterior margin evenly straight, lateral margin of head anterior to eyes slightly convex. Eyes circular, placed above midline of head (PoOC/CL: 0.10±0.02; 0.09–0.12). Mandibles triangular with six teeth. Clypeus carinate, its anterior border angularly produced in the middle (ClyL/GPD: 0.20±0.06, 0.16–0.23). Antennal scape long, surpassing the occiput by the length of one basal funiculus (SL/CS: 0.34±0.02; 0.32–0.34). In lateral view, anterodorsal corner of pronotum rounded, mesonotum dorsum inclined toward nearly straight propodeum face (MW/ML: 0.19±0.02, 0.18–0.20; MPH/ML: 0.13±0.02, 0.12–0.14). In lateral view, petiolar node longer than wide, with flat summit, its anterior face leaning forward. Ants finely foveolate throughout, apparently shiny. Entire body, including mandibles and appendages, covered with plentiful, erect, whitish setae, uneven in length, some long. Head, mesosoma, and gaster dark brown to black; antennae, mandibles, tibiae, and tarsi reddish brown.
Major
Characteristics of minor workers, except: head much wider posteriorly (CS: 1.68±0.07, 1.61–1.76; CWb/CL: 0.91±0.02, 0.89–0.92); lateral margins convex and converging towards base of mandible. Eyes circular placed dorsolaterally midway from the occipital margin (PoOC/CL: 0.30±0.00, 0.29–0.30). Clypeus with a short rectangular lobe with rounded lateral angle (ClyL/GPD: 0.85±0.03, 0.81–0.88). Antennal scape short, not reaching the occipital margin (SL/CS: 0.57±0.02, 0.56–0.59). Dorsal outline of mesosoma interrupted by sutures, metanotal suture forms a canal. Head dorsum and mesosoma coarsely reticulate-punctate, petiole finely striolate, gaster imbricate and shiny.
Holotype worker: Madagascar, Province Toliara, Parc National de Tsimanampetsotsa, Forêt de Bemanateza, 20.7 km 81°E Efoetse, 23.0 km 131°SE Beheloka, –23.99222, 43.88067, 90 m, spiny forest/thicket, under stone, 22–26 March 2002 (BLF), collection code: BLF06310, specimen code: CASENT0445276 (CASC). Paratypes. Four workers with the same data as holotype CASENT0445284, CASENT0445285, CASENT0445287, CASENT0445288 (CASC).
Etymology
The new species is dedicated to Jean Jacques Rafanomezantsoa, who has been a Malagasy ant collector for more than twenty years.
