Specimen Label

This species is currently only known from Borneo (Brunei, North Kalimantan, Sarawak). One colony was discovered in an artificial nest close to the “visitor canopy walkway” in the Ulu Temburong National Park, Brunei. The nest contained only specimens of C. paracolobopsis and may have been a complete colony (or fragment thereof) with minor workers, major workers, gynes and brood (see notes on Camponotus inquilinus).


Zettel et al. (2018) - Minor worker: Black species with brown scape and base of funiculus; only on tergites 3–4 with very narrow, translucent hind margins. Long white standing setae abundant all over dorsum. Basal margin of clypeus with distinct concavity. Flagellum of normal length. Pronotum with distinct sculpture, but somewhat shiny. Dorsal outline of mesonotum and propodeum slightly convex, propodeum moderately downcurved. Petiolar node high and narrow in lateral aspect.

Major worker: Colour as in minor, except anterior margin of head medium to yellowish brown; anterior part of frons and mandibles reddish brown. Head with scattered medium-sized punctures, denser on genae and clypeus. Clypeus with about 14–16 groove-like punctures, base with narrow medial impression. Genae with some comparatively large punctures.

Among the (almost) entirely black species, C. paracolobopsis has the major workers with the most strongly sculptured head (major worker of Camponotus paraleonardi). Camponotus paraleonardi differs by the golden hair on mesosoma and gaster, Camponotus kutteri by distinct pale hind margins of gaster tergites. Camponotus benguetensis from the Philippines is most similar; see the comparative notes of this species.

The paratype series from Kalimantan differs from the Brunei series by very dark antennae and, in major workers, by less obvious grooves on clypeus and genae between the very pronounced microsculpture, but is regarded as conspecific. These specimens resemble Camponotus benguetensis, but differ in the structures at clypeus base.

Ward’s Indices: ASM/HWex 0.26–0.28; ASM/CLW 0.55–0.65; CLW/CLL 1.15–1.38.

Structures: Head roundish, uniformly reticulated and matt dorsally and laterally, ventrally with slightly reduced microsculpture and somewhat shiny. Lateral outline of eye and head contiguous. Vertex moderately raised, not domed. Frons with hardly discernable shiny midline. Clypeus with distinct emargination at middle of basal margin, with distal margin slightly protruded in middle, with very narrow often reduced shiny midline. Mandible scarcely punctured, with five teeth. Mesosoma slender and low, entirely reticulated, but with a silky shimmer; dorsal outline convex, on pronotum and propodeum moderately convex, without distinct indentions. Petiolar node posteriorly very high, its anterior and posterior face parallel, apex strongly obliquely truncated. Gaster tergites entirely with dense reticulation, including very narrow translucent margins on tergites 3–4. Pilosity: White long standing setae abundant all over dorsum, longest on mesonotum, propodeum, gaster tergites 1 and 4. Subdecumbent pubescence short, thin, whitish, extremely sparse and inconspicuous on head, dense and distinct on mesosoma, petiole, and gaster. Colour: Trunk, mandibles, palpi, and legs black. Antenna black, except larger part of scape and basis of funicular segments 1–4(5) brown or orange brown. Tergites 3–4 with very narrow translucent margins.


Paratypes (n = 6): HW 1.76–2.02; HL 2.00–2.28; SL 1.22–1.35; SW 0.17–0.23; EL 0.54–0.58; ML 2.35–2.67; HaL 0.28–0.33; FeL 1.60–1.76; CI 85–90; SI 67–70; EI 28–33; FeI 84–97.

Structures: Head squared, moderately longer than wide. Eyes small, laterally not reaching sides of head. Ocellar scars absent. Frontal carinae prominent, curved.
