Common Name
Language: Japanese

An arboreal species that nests in bark or crevices in tree trunks of coniferous and mixed forests. During a field survey in India, Dhadwal & Bharti (2023) report this species was collected from Solang, Himachal Pradesh. The nest was found under the stone, the colony was small and having few minor workers only. The area is mostly surrounded by Deodar and Pine trees, with an average daily temperature of 28°C.


Japanese Ant Image Database - Total length of workers around 5 - 6 mm. Body black; pronotum brownish in many individuals. First and 2nd gastral terga each with a pair of yellowish spots. Metanotal groove not incised dorsally; petiole with hairs.

Dhadwal & Bharti (2023) - Camponotus quarinotatus resembles Camponotus keihitoi, but both species can be easily distinguished by the following combination of characters:

  • C. keihitoi (minor worker)
    • the metanotal depression is distinct
    • pilosity is absent on the mesosoma and the petiole
    • the clypeal margin is transverse anteriorly
  • C. quarinotatus (minor worker)
    • the metanotal depression is indistinct
    • the mesosoma and the petiole are pilose
    • the clypeal margin is convex anteriorly
