Only known from the type locality in Phang-nga Province, Thailand.

Identification

Zettel et al. (2018) - Minor worker: Body chiefly light reddishbrown; head somewhat darker; gaster ventrally infuscated. Pronotum with long standing setae. Trunk with dense microreticulation, matt; only pronotum with weaker sculpture, shiny. Clypeus basally shallowly emarginated. Flagellum of normal length, antennomere 7 about twice as long as wide. Dorsal outline of entire mesosoma slightly convex, of pronotum moderately convex, in front of propodeum with shallow depression.

Major worker unknown.

This species is similar to Camponotus sophiae from the same locality. It differs by a shinier, less reticulated pronotum, a normally long antennal flagellum, a concave dorsal outline between mesonotum and propodeum, and slightly shorter and less abundant standing setae. It differs from Camponotus concurrens by the only moderately convex pronotum (humped in minors of C. concurrens) and bearing long standing setae, and by the shallow depression in the anterior part of the propodeum.

Holotype: HW 1.22; HL 1.41; SL 1.28; SW 0.15; EL 0.38; ML 1.89; HaL 0.27; FeL 1.60; CI 86; SI 105; EI 31; FeI 131. Ward’s Indices: ASM/HWex 0.29; ASM/CLW 0.59; CLW/CLL 1.47. Paratypes (n = 3): HW 1.24–1.28; HL 1.37–1.43; SL 1.26–1.28; SW 0.14–0.15; EL 0.38–0.39; ML 1.83–1.92; HaL 0.20–0.25; FeL 1.57–1.70; CI 86–94; SI 100–102; EI 31; FeI 122–137. Ward’s Indices: ASM/HWex 0.27–0.28; ASM/CLW 0.55–0.57; CLW/CLL 1.40–1.56.

Structures: Head roundish, uniformly reticulated and matt dorsally and laterally, ventrally with slightly reduced microsculpture and somewhat shiny. Lateral outline of eye barely meeting outline of head. Vertex slightly domed. Frons with very narrow shiny midline. Clypeus with very small emargination at middle of basal margin, distal margin slightly protruded in middle, basally with a very short, deep, shiny median impression. Mandible punctate, with five teeth. Mesosoma slender, moderately low; mesonotum and propodeum densely reticulated and matt, pronotum with indistinct sculpture, shiny; dorsal outline of pronotum, anterior portion of mesonotum and posterior slope of propodeum distinctly convex, outline of posterior mesonotum and anterior part of propodeum slightly concave, creating a low depression between mesonotum and propodeum. Petiole with moderately high node, its anterior and posterior face parallel, apex strongly obliquely truncated. Gaster tergites with dense reticulation until hind margin.

Pilosity: Pale, moderately long standing setae scattered all over dorsum, longest on propodeum and gaster tergite 1. Subdecumbent pubescence short, thin, whitish, rather inconspicuous.

Colour: Body reddish-brown, tending to orange on mesosoma, gaster and scapes; head somewhat darker; ventral side of gaster, antennal flagellum, maxillary palpi, and legs dark brown; gastral tergites 2–4 with very narrow translucent margins.
