Type species: Bifrontia compactior Norman
Notes: Bifrontia was introduced by Norman (1872) with two species B. compactior and B. laxa. Boonmee et al. (2014b) restudied the holotype of B. compactior and designated the species as the lectotype of the genus. Boonmee et al. (2014b) accepted Bifrontia as a genus of Tubeufiaceae.
