Poyntonophrynus, also known as pygmy toads, are a genus consisting of ten true toad species native to Sub-Saharan Africa.[2][3] Originally, all Poyntonophrynus species were included in the genus Bufo. The genus was split due to large enough taxonomic divergence as evidenced by molecular markers.[1] The genus is named in honour of John C. Poynton [fr], South African herpetologist, with phrynus being Greek for toad.[1]

Taxonomy and systematics

[edit]

Poyntonophrynus corresponds to the former Bufo vertebralis group.[1][2] Poyntonophrynus is the sister taxon of Mertensophryne. Some molecular studies have suggested polyphyly of Poyntonophrynus, but the conclusion is likely to have been caused by sequences representing a different species than assumed.[2]

Description

[edit]

Poyntonophrynus are small toads.[4] They lack a tarsal fold, and their parotoid glands are indistinct and flattened. The tympanum is small but distinct.[1]

Species

[edit]

The species in this genus are:[2][3]

Sclerophrys urunguensis likely belongs to this genus, but remains formally in Sclerophrys (former Amietophrynus).[5]
