Camponotus lokobe is endemic to Madagascar and restricted to the rainforest of the RNI Lokobe in the north of the island. Nest sites have been found in rotten logs.
Identification
Rakotonirina and Fisher (2022) - With head in full-face view, lateral cephalic margins converging posteriorly towards eye level, then rounding to occipital corner of head; anteromedian margin of clypeus noticeably excised medially; two apical teeth of mandible normally spaced; lateral cephalic margin anterior to eye level covered with erect hairs.
Camponotus lokobe can be separated from Camponotus dufouri and Camponotus tendryi by the fact that its clypeus is characterized by a medially excised anteromedian margin.

Morphological measurements: see Appendix 1 and Ratios of morphometric data for majors and minors
Minor With head in full-face view, lateral cephalic borders anterior to level of eye parallel to each other, converging strongly towards posterior margin behind eye level; eye large and convex (EL/CS: 0.30±0.01; 0.27–0.31), breaking lateral margin of head, level of its posterior margin located approximately at posterior 1/3 of head (PoOc/CL: 0.29±0.01; 0.28–0.31); frontal carinae not widely opened (FR/CS: 0.26±0.01;0.25–0.27), posteriorly parallel, distance between them larger than smallest distance to eye; clypeus with anterolateral angle and medially slightly concave anteromedian margin; two apical teeth of mandible distantly spaced; antennal scape relatively long (SL/CS: 1.80±0.03; 1.76–1.85). Mesosoma long and low (MPH/ML: 0.29±0.01; 0.29–0.30), with its dorsal outline almost flat; metanotal groove feebly visible; propodeal dorsum feebly convex anteriorly and flat posteriorly; junction of propodeal dorsum to declivity bluntly angulate; propodeal declivity 1/3 length of the dorsum. Petiole nodiform, tapering dorsally; its dorsal margin inclined posteriorly and forming a blunt angle to anterior face; posterior face 2 × as high as the anterior; femur of hind leg rounded axially, without twist near base.
First and second gastral tergites without a pair of white spots; with head in full-face view lateral margin covered with erect hairs; near posterior margin of head with a pair of erect hairs; antennal scape covered with erect hairs inclined at ca. 45°; pronotum with numerous erect to suberect hairs; a pair of erect hairs present on posterodorsal angle of propodeum.
Type Material
- Holotype worker. MADAGASCAR: Province Antsiranana: RNI Lokobe, 6.3 km 112° ESE Hellville, Nosy Be, -13.41933, 48.33117, 30 m, rainforest, ex rotten log, 19–24 Feb 2001, (Fisher, Griswold et al.) collection code: BLF03476, specimen code: CASENT0436584 (CAS).

Etymology
The species name lokobe is a singular non-Latin noun used in apposition and refers to the type locality.
