Karmaly & Narendran, 2006
Other than a statement that the type was collected from a disturbed habitat, nothing is known about the biology of Camponotus keralensis.
Karmaly & Narendran (2006) - This species comes close to Camponotus thraso in the following characters: 1. Head rectangular; 2. Clypeus carinate with a short lobe, its anterior margin transverse; 3. Antennae slender filiform; 12 jointed; 4. Thorax viewed from side forming a regular arch; 5. Circular anal orifice at the apex of the hypopygim ventrally guarded by guard hairs. However it differs from Camponotus thraso in having: 1. Teeth not obsolete (in Camponotus thraso teeth obsolete); 2. Meso-metanotal suture distinct (in Camponotus thraso meso-metanotal suture indistinct); 3. Petiolar node convex in front, flat posteriorly (in Camponotus thraso petiolar node biconvex as long as broad).
