Amnirana albolabris (Hallowell, 1856) Photo figure 23A TYPE LOCALITY.— “West Africa”. Perret (1977) restricted the type locality to “ Gabon ” and Jongsma et al. (2018) deduced that it is “north of the Ogooué River in Gabon ”.
DISTRIBUTION.— This species is widespread across lowland rainforests of Gabon, Equatorial Guinea, Cameroon, Democratic Republic of Congo, Republic of Congo, Central African Republic and Uganda, also reaching northern Angola (fide Marques et al. 2018). In Equatorial Guinea, it occurs in Río Muni, where it has been recorded from Cabo San Juan and Monte Alén (Boulenger 1903; De la Riva 1994). Published records from Bioko are at Musola, San Carlos de Luba region, Ureca, and Basupu (Boulenger 1900, 1906a; Mertens 1965; Hydeman et al. 2017) (Map 25C).
COMMENTS.— Amnirana albolabris is a polyphyletic taxon that contains several undescribed species (Jongsma et al. 2018). Populations from Bioko form part of an undescribed species closely related to the nominotypic A. albolabris, which is present in Río Muni (Jongsma et al. 2018). The undescribed species from Bioko is also recorded from the coast of Cameroon (Jongsma et al. 2018); a similar distribution pattern is shown by Petropedetes newtonii (Sánchez-Vialas et al. 2018).
