Rounded Acne Ants
(See also Orthonotomyrmex, Myrmepinotus, Myrmopiromis, and Myrmisolepis.)
Diagnosis. Emery (1925) - "Worker and female. - Medium-sized species; caste dimorphism somewhat marked, as in Myrmopiromis. Head as in Myrmopiromis. In majors and queens, the anterior surfaces of head, at least cheeks and clypeus, are with large, internally punctate foveae which are more-or-less numerous and dull. Medial clypeal carina present in minors, absent in majors; anterior clypeal margin with short, rounded or truncate lobe, or devoid of lobe in majors. Pronotum never shouldered; rest of mesosoma and petiolar scale as in Myrmopiromis. Cuticle generally dull, at least on head and mesosoma, gaster often shining; pilosity highly variable. Male. - Forel and Santschi have described several males of this subgenus; I know of none in kind.
Geographical distribution of species. - Afrotropics, Malagasy region including islands; [at least] one species known in Northern India."
Myrmotrema is currently a subgenus of Camponotus.
grandidieri species group
Rakotonirina et al. (2017) - The Camponotus grandidieri species group is currently equivalent to the subgenus Myrmotrema. Although we continue the practice of placing Camponotus taxa in their respective subgenera, this study does not address the support of subgenera as monophyletic lineages. Because initial results suggest many of the subgenera are not natural, we employ the species group nomenclature in the present study. See the Camponotus grandidieri species group page for more information about this group.
