Comments. Within the subgenus Dendromyrmex this species is distinguished by having a sculpted pronotum with transverse, wrinkled striae dorsally, and similar striae arranged vertically on its side; antennal scapes with abundant hairs; dorsum of gaster mostly smooth and shiny ( Mackay, 2004). We examined specimens from canopy fogging and hand-collected samples from lowland Amazonian forests. Antmaps shows a record of C. traili for Ecuador, without reference though, only a non-traceable collection number is indicated. Camponotus traili was previously known from the Amazon region of Colombia, Venezuela, Bolivia, and Brazil, ( Janicki et al., 2016).
