Correction to the type locality of Tomopterna ahli (Deckert, 1938) (Anura: Pyxicephalidae), with the designation of a neotype
No full textDeckert described a Tomopterna as Arthroleptella ahli from South Africa in 1938. We demonstrate that the type of Tomopterna ahli (Deckert, 1938) was actually collected in Namibia, and that this nomen is a senior synonym of Tomopterna damarensis Dawood & Channing, 2002. We designate a neotype for Tomopterna ahli (Deckert, 1938
Alain Dubois’ contributions to African amphibian nomenclature
No full textAlain Dubois has made important contributions to our understanding of African amphibians. His 1981 interpretations based only on earlier literature include the recognition of a series of subfamiles in the Ranidae. Later he added data derived from his work on the morphology of museum specimens, defining new subdivisions within the Raninae. By 2005 he was using molecular evidence to provide a testable working taxonomy, and proposed an arrangement including the epifamily, superfamily, family and subfamily division
The larva of Schismaderma carens (Smith, 1849) (Anura: Bufonidae): a redescription
Full text linkWe describe the outer morphology of Schismaderma carens larvae in greater detail than previous
studies, with special attention to the histology of the unusual head fold in this taxa. The oral cavity is
described for the first time. External morphology, including the oral disc (LTRF 2/3), overall shape,
biometrical indices, oral cavity morphology, and the filter apparatus confirm that Schismaderma
carens is a generalized filter-feeding tadpole, not very different from most toad tadpoles of the world.
Internally some papillae around the choanae appear taller and fused than in common toad tadpoles,
but their function is unclear. The dorsal horseshoe-shaped head fold is an integumental expansion, rich
in blood vessels and surrounded by a thin epithelium consistent with it serving a respiratory function.
Its role is interpreted as an additional gas exchange site allowing the utilization of alpha-mesosaprobic
and polysaprobic water
