The Bufo tuberosus species group with the description of a new species from the rainforest of Cote-d'Ivoire

A very small species of toad similar to Bufo tuberosus was discovered in a collection made in West Africa by M. Lamotte in the late 1960s. In the 1980s a second specimen of this species from Cote-d'Ivoire was donated to the Museum d'histoire naturelle de Geneve. This paper describes the new species, B. amieti, presents additional data on B. tuberosus, compares these species to others and hypothesizes an origin of B. amieti and B. tuberosus by geographical isolation of a common ancestor in eastern and western blocks of equatorial rainforest separated by the V-Baoule during past interpluvial periods.
