Identification

Dhadwal & Bharti (2023) - The distinguishing characteristics of the species are as follows:

  • the head is longer than broad
  • the petiole node is thick and bluntly rounded
  • the tibiae are compressed without spined beneath
  • body is reticulate punctate, somewhat matte and sparsely pubescent

This species resembles Camponotus mitis and can be distinguished by the following combination of characters:

  • C. meghalayaensis (major worker)
    • the anterior clypeal margin is medially emarginated
    • the body is covered with sparse erect hairs or less pilose and the node of petiole is thick and bluntly rounded in shape
  • C. mitis (major worker)
    • the anterior clypeal margin is not emarginated
    • the body is covered with erect dense pilosity and the node of the petiole is thin and scale-like

Description

Worker

Major Holotype HL 2.58; HW 2.34; EL 0.59; SL 2.25; PW 1.23; WL 3.07; MTL 1.47; HTL 2.54; PL 0.69; PH 0.70; GL 2.33; TL 8.67; CI 83; SI 96; REL 22; PrI 52. Paratype (n = 1) - HL 2.66; HW 2.48; EL 0.61; SL 2.37; PW 1.35; WL 3.36; MTL 2.11; HTL 2.82; PL 0.77; PH 0.73; GL 2.46; TL 9.25; CI 107; SI 95; REL 22; PrI 54.

Habitus. In full-face view, head longer than broad (CI 83–107), posterior margin of the head rounded and shallowly concave in the middle, lateral margins slightly converging towards the anterior side; anterior clypeal margin medially emarginated; mandibles with 7 teeth; eyes large placed near the midlength of the head; antennae long, slender and 12-segmented; scape short (SI 95–96) surpassing posterior margin of the head by ¼ of its length. In dorsal view, mesosoma broad and elongated, pronotum anteriorly narrow (PrI 54); pro-mesonotal suture and metanotal groove distinct; mesosoma form a single convexity with mesonotum somewhat higher than the pronotum and propodeum in lateral view; propodeal declivity almost straight; propodeal spiracle oval in shape placed below the margin of propodeal declivity; petiole node is thick and bluntly rounded; tibiae compressed; gaster elongated.

Sculpture. Head and mesosoma reticulate punctate; head somewhat matte, whereas mesosoma and gaster are gleaming.

Pilosity and pubescence. Pubescence sparse, with a few setae present on the vertex and anterior margin of the clypeus; lateral sides of the head covered with sparse short erect hair; hind tibia densely setose, without a row of spiny bristles on ventral margin in addition to 3–4 suberect setae close to the apical spur.

Colouration. Head and gaster dark brown; mesosoma yellowish brown to reddish brown; legs lighter brown.

Minor Paratypes (n = 5) - HL 1.76–1.88; HW 1.02–1.11; EL 0.45–0.49; SL 2.29–2.41; PW 1.02–1.06; WL 2.66–2.82; MTL 1.80– 1.96; HTL 2.25–2.54; PL 0.57–0.65; PH 0.61–0.65; GL 2.29–2.58; TL 7.28–7.93; CI 57–59; SI 217– 224; REL 25–26; PrI 95–100.

Differs from the major worker in the following characteristics: head smaller and elongated (CI 57–59), longer than broad and narrower posteriorly than in the fornt, with the posterior margin almost rounded and sub-parallel lateral margins; anterior clypeal margin straight; eyes comparatively large touching the lateral sides of the head; mandibles with 6 teeth; scape distinctly long (SI 217–224) surpassing posterior margin of head by half of its length; mesosoma is shorter than the one of major worker.
