Specimen Labels

Dhadwal & Bharti (2023) report this species from India, where they found a nest inside the trunk of a tree. The workers were collected from both the grass and tree branches. The average daily temperature of the region was 28°C and it primarily consists of residential areas.

Identification

Dhadwal & Bharti (2023) - This species resembles Camponotus nicobarensis but can be easily separated from the latter by following a combination of characteristics:

  • C. nicobarensis (major worker)
    • the masticatory margin is armed with 5 teeth
    • the dorsal surface of the gaster is marked with black and yellowish alternate bands
    • the body is covered with very sparse and erect or sub-erect hairs
  • C. nicobarensis (major worker)
    • the masticatory margin of the mandibles are armed with 7 teeth
    • the gaster is brownish with a blackish edge of the proceeding tergite
    • the head, mesosoma, and gaster are all covered with very long, dense, and erect or sub-erect hairs on their dorsal surfaces

Description

Worker

Major Dhadwal & Bharti (2023) - (n = 7) HL 2.97–3.16; HW 2.72–3.03; EL 0.60–0.62; SL 2.70–2.85; PW 1.36–1.72; WL 3.41–3.65; MTL 2.35– 2.54; HTL 3.03–3.22; PL 0.80–0.93; PH 0.93–1.05; GL 2.66–3.41; TL 9.84–11.15; CI 91–95; SI 94–99; REL 19–20; PrI 50–56.

Habitus. In full-face view, head subtriangular, longer than broad (CI 91–95), with posterior margin emarginated medially, occipital corners rounded, lateral sides convex and converging anteriorly; clypeus broad and flat with a transverse anterior margin and pointed lateral angles; mandibles massive and triangular, with 5 teeth; eyes large, placed dorsally, slightly above the mid-length of head; antennae long, slender and 12-segmented, scape long (SI 94–99) surpasses the posterior head margin by ¼ of its length. In dorsal view, mesosoma anteriorly broad (PrI 50–56) and progressively narrow posteriorly; promesonotal suture and metanotal groove distinct; pronotum broader than rest of mesosoma; mesosoma forming a single convexity in lateral view; propodeal declivity slightly concave; propodeal spiracle elongated or slit-like placed below the margin of the propodeal declivity; anterior face of petiole convex and posterior face straight, dorsally convex and slightly emarginated; tibiae compressed; gaster large and oval.

Sculpture. Head, mesosoma, petiole and gaster microreticulated; clypeus, genae and antennal scape punctured; mandibles with scattered punctures. Except for the anterior region of the head and the gaster, the body is gleaming.

Pilosity and pubescence. Entire body covered with sparse, pale yellow and erect hairs; dense erect hairs present on anterior clypeal margin and on apex of the gaster; ventral margin of the hind tibia lacking a row of spiny bristles, but bearing 3–4 suberect setae close to apical spurs; body covered with short dense decumbent hairs.

Colouration. Mandibles, genae, antennal scape and appendages reddish brown; vertex with dark brownish band; posterior to the genae, mesosoma and petiole light brownish; dorsal surface of the gaster with alternating black and yellowish bands.

Minor Dhadwal & Bharti (2023) - (n = 7) HL 1.64–2.01; HW 0.94–1.06; EL 0.45–0.48; SL 2.37–2.54; PW 0.86–0.94; WL 2.74–3.03; MTL 2.05– 2.09; HTL 2.33–2.66; PL 0.61–0.69; PH 0.61–0.69; GL 2.25–2.47; TL 7.24–8.20; CI 39–53; SI 239– 252; REL 24–27; PrI 88–91.

Same characteristics as of the major worker, except: head relatively small (CI 39–53), elongated and subrectangular with parallel lateral sides, posterior margin of the head convex; scape long (SI 239–252), surpassing the posterior head margin by more than half of its length.
