Sclerophrys Tschudi, 1838

This genus was formerly known as Bufo or Amietophrynus, but it is now named Sclerophrys (Ohler and Dubois 2016) . We were unable to identify any of the three species of Sclerophrys toads to a described species with certainty, and probably at least two of them represent undescribed species. All three seem to be confined to forested habitats. Interestingly, none of the typical and usually common (semi-) synanthropic species of the Congo ( S. gutturalis, S. pusilla, S. regularis) was recorded in this survey. Sclerophrys toads from the forests of Central Africa form a clade containing S. camerunensis, S. funerea, S. gracilipes, S. kisoloensis, S. villiersi, and several undescribed species (Liedtke et al. 2016, 2017), which for simplicity we tentatively name as the S. camerunensis-gracilipes group, and are in need of taxonomic revision (E. Greenbaum et al., in prep.).
