Arcius species, like other plesiadapiforms, have enlarged and protruding lower incisors (Conroy, 1990). As with most paromomyids, this species had slender lower incisors; tall and pointed posterior lower premolar; low-crowned lower molars with short, squared trigonids and broad, shallow talonid basins; square upper molars with expanded basins; upper and lower molars that were elongated (Fleagle, 1999).
Arcius fuscus was found in Europe, specifically in France, during early Eocene epoch (Fleagle, 1999).
