Camponotus kutteri

Only known from the type locality on Simeulue Island, Indonesia (Zettel et al., 2018).

Identification
Zettel et al. (2018): Trunk, antennae and legs black; only mandibles orange; tergites with narrow but distinct pale hind margins. – Minor worker: Body matt to moderately shiny. Vertex moderately high. Posterior margin of clypeus concave. Dorsal outline of mesosoma strongly convex, with a shallow depression between mesonotum and propodeum.

Major worker: Head squared, about as long as wide; strongly shiny, with scattered punctures; some notably large punctures on frons.

The species fits relatively well in the species group, except for the distinct pale yellowish hind margins of gaster tergites in both major and minor workers, which resemble some species of Myrmamblys. The major worker strongly differs from other related black species by the shiny head, the minor worker by the more concave base of the clypeus.

Further notes: Forel (1915) described all morphs including males. He compared C. kutteri with Camponotus punctaticeps from Java, which has been listed as either a member of the subgenus Myrmamblys (Forel 1914, Emery 1925) or Colobopsis (McArthur 2012) by previous authors. According to the same publication (Forel 1915), the species lives in Sinabang in sympatry (but not necessarily at the same localities) with “Camponotus (Colobopsis) pilosus Smith”. This taxon is a member of the Colobopsis cylindrica group and is presently under investigation.
