|Formica fulvopilosa, now Camponotus fulvopilosus
Furry Carpenter Ants
Diagnosis. Emery (1925) - "Workers and queens - Large to medium species; caste dimorphism somewhat marked. Head of majors and queens wider than long, narrower anteriorly, widely truncated or sometimes slightly emarginate posteriorly; head of minors similar, but less broad. Cheeks without large punctae, as are characteristic of which are characteristic for Myrmotrema. Clypeus medially carinate, sometimes carina absent in majors; clypeus with short, truncated, or rounded anterior lobe. Mesosomal dorsum arched, continuous (fulvopilosus niveosetosus groups), or more-or-less strongly impressed anterior to propodeum (chrysurus and sclaris groups); pronotum sometimes with narrowly rounded (blunt) tooth at the shoulders (fulvopilosus, ellioti). Petiolar scale usually not thick, but thinned or sharp along margins. Cuticle matte, black or brown, most often lined with coarse, yellow, red, or white setae. Or with fine pubescence, forming gastral fur. Male. - Similar to Myrmepinotus. I know the males of C. fulvopilosus and C. darwini. The first has longer antennae, with scapes extending beyond posterior head margin by more than half their length; pedicel and flagellum as in Myrmepinotus.
Geographical distribution of species. - Southern and Eastern Africa, Madagascar, Mascarenes, and Seychelles."

Myrmopiromis is currently a subgenus of Camponotus.
Species groups of Myrmopiromis
Emery (1925) divided Myrmopiromis into three species groups, which he diagnosed as follows:
"Group I: fulvopilosus
Diagnosis. - Worker. - Slender, large in size; dorsum of mesosoma continuous, pronotum shouldered, tibiae compressed and with bristles on ventral margin.
Group II: niveosetosus
Diagnosis. - Worker. - Generally medium in size; body more-or-less squat; mesosomal dorsum continuous; pronotum rounded or shouldered; tibiae without bristles on ventral margin.
Group III: chrysurus
Diagnosis. - Worker.- Medium in size; mesosomal dorsum impressed anterior to propodeum; propodeum rounded (Myrmopelta [part] and Myrmisolepis [part], sensu Santschi)."
