Camponotus ivadia has thus far been collected only in the Forêt d’ Ampondrabe within Ankarana Reserve, a region with tropical dry forest located in the northern portion of Madagascar. All specimens were collected by beating vegetation.
Identification
Rasoamanana and Fisher (2022) - A member of the Camponotus madagascarensis species group. Integument dark brown, apparently shiny; hairs on mesosoma and petiole blunt-tipped; fine, pointed hairs on head and gastral dorsum; anterior clypeal margin with straight rectangular lobe; dorsal outline of mesosoma nearly evenly arcuate; petiole higher than long.
This species is easily recognized within the madagascarensis group as one of few back and shiny species with white standing pubescence.

Description
Worker
Morphological measurements: see Appendix 1 and Ratios of morphometric data for majors and minors
Minor
Medium-sized species. Absolute cephalic size (CS: 1.21±0.19, 1.13–1.30). In full-face view, head almost quadrate, with feebly convex posterior and lateral border (CWb/CL: 0.35±0.03, 0.33–0.36). Eyes elliptical, placed next to the lateral margins of head (PoOC/CL: 0.10±0.01, 0.10–0.11). Mandibles triangular with six teeth. Anterior clypeal margin angularly produced, with straight lateral border and rounded anterolateral corner. Antennal scape long, surpassing the occipital corner by the length of two basal funiculi (SL/CS: 0.39±0.02, 0.38–0.40). In lateral view, pronotum with short anterolateral margination, mesosoma moderately convex, propodeum angular in profile, with unequal basal and declivitous faces, each straight in profile and meeting at a rounded obtuse angle (MW/ML: 0.21±0.03, 0.19–0.22; MPH/ML: 0.16±0.01, 0.16–0.17). In lateral view, petiole rather narrow, its anterior face convex and its posterior face flattened. Body finely imbricate. Hairs whitish; enlarged, whitish hairs with blunt tip on mesonotum, propodeum, and petiolar dorsum; filiform, pointed, grayish hair on head, pronotum, and gastral segment; pubescence white, short, and more abundant across entire dorsum. Head, mesosoma and gaster dark brown, femora, tibia, and funiculi brown, scape and basitarsi slightly lighter.
Major
Characteristics of minor workers, except: head as long as wide, posterior borders medially concave and subparallel, lateral sides diverging apically (CS: 1.93; CWb/CL: 0.93). Eyes circular, placed dorsally in the middle of the lateral borders (PoOC/CL: 0.28). Anterior clypeal margin forms a short, rounded, rectangular lobe, slightly concave medially (ClyL/GPD: 0.84). Antennal scape short, just reaching the occipital border (SL/CS: 0.69). Sculpture, pilosity, and color as in minor worker.
Type Material
Holotype worker: Madagascar, Province Antsiranana, Forêt d’ Ampondrabe, 26.3 km 10° NNE Daraina, tropical dry forest, on low vegetation, –12.97, 49.7, 175 m, 04 November 2009 (BLF) collection code: BLF10105, specimen code: CASENT0498634 (CASC). Paratype. One worker with same data as holotype but specimen coded as CASENT0498635 (CASC).
Etymology
The species epithet ivadia is derived from the low vegetation microhabitat it prefers.
