This species, known from a single collection and two specimens, was found in lowland primary rainforest where the workers were foraging on vegetation (Shattuck & Janda 2009).

Identification

Shattuck & Janda (2009) - minor Enlarged hairs on pronotum present, cream-colored and covering majority of dorsal surface; pubescence on dorsum of head abundant and closely spaced; erect hairs on dorsum of head between eyes and frontal carinae black.

The head shape is similar to Camponotus cyrtomyrmodes and Camponotus subpilus in being widest above the eyes and weakly convex between the eyes and mandibular insertions (in full face view), but differs in having the eyes located much more posteriorly on the head capsule. It also differs in having denser pubescence and more abundant enlarged erect hairs on the head and mesosoma compared to either of these species. This species, and other members of the Camponotus aureopilus group, are best placed within the subgenus Myrmophyma, noting that this placement is based on overall morphological similarity and a more rigorous study of the subgeneric and species-group classification within the genus is long overdue.

Type Material

Holotype worker and 1 worker paratype from Kaiangabip Village, Upper Fly River, 40 km SE Tabubil, 5° 32' 47" S, 141°30' 14" E, 150 - 250 m a.s.l., Western Province, Papua New Guinea, March 2008, leg.

Etymology

We dedicate this species to Roy Snelling, who recently passed on while on a collecting trip to western Kenya, one of his favorite stomping grounds. Roy had been more than generous over many years, always there with a kind (or harsh, as appropriate) word and a willingness to share his extensive knowledge, experience and material.
