Correction to the type locality of Tomopterna ahli (Deckert, 1938) (Anura: Pyxicephalidae), with the designation of a neotype
(Magnolia Press, 2019)Deckert 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 ... -
Correlating early evolution of parasitic platyhelminths to Gondwana breakup
(Oxford University Press / Society of Systematic Biologists, 2011)Investigating patterns and processes of parasite diversification over ancient geological periods should involve comparisons of host and parasite phylogenies in a biogeographic context. It has been shown previously that the ... -
DDT exposure of frogs: a case study from Limpopo Province, South Africa
(Elsevier, 2016)Amphibians are globally under pressure with environmental contaminants contributing to this. Despite caution aired more than 80 years ago of threats posed to amphibians by DDT spraying for disease vector control, no data ... -
Identification of sand frogs (Anura: Pyxicephalidae: Tomopterna) from Kenya with the description of two new species
(Magnolia Press, 2013)African sand frogs in the genus Tomopterna presently include 13 species. These are known to be highly cryptic and morphologically similar. Despite increased effort in the recent past, the taxonomy of the group is still ... -
An integrative taxonomic revision and redefinition of Gephyromantis (Laurentomantis) malagasius based on archival DNA analysis reveals four new mantellid frog species from Madagascar
(Pensoft Publishers [Commercial Publisher], 2022)The subgenus Laurentomantis in the genus Gephyromantis contains some of the least known amphibian species of Madagascar. The six currently valid nominal species are rainforest frogs known from few individuals, hampering a ... -
Leapfrogging into new territory: how Mascarene ridged frogs diversified across Africa and Madagascar to maintain their ecological niche
(Elsevier, 2017)The Mascarene ridged frog, Ptychadena mascareniensis, is a species complex that includes numerous lineages occurring mostly in humid savannas and open forests of mainland Africa, Madagascar, the Seychelles, and the Mascarene ... -
Metazoan parasites of anurans from the Vhembe area, Limpopo, South Africa
(North-West University (South Africa), 2022)Amphibians were the first vertebrate group to appear on land about 350 m.y.a and have diversified and colonized all suitable continents and islands. Amphibians are hosts to vast numbers and an astonishing diversity of ... -
Monophyly of the species of Hepatozoon (Adeleorina: Hepatozoidae) parasitizing (African) anurans, with the description of three new species from hyperoliid frogs in South Africa
(Cambridge Univ Press, 2018)Haemogregarines (Apicomplexa: Adeleiorina) are a diverse group of haemoparasites reported from almost all vertebrate classes. The most commonly recorded haemogregarines to parasitize anurans are species of Hepatozoon ... -
Multi-locus phylogeny and evolution of reproductive modes in the Pyxicephalidae, an African endemic clade of frogs
(Unisa Press/Taylor & Francis, 2011)The ranoid family Pyxicephalidae is an endemic group of African frogs, with the majority of its diversity concentrated in South Africa. Here we present the first molecular phylogeny that includes as many as nine of the ten ... -
A new grass frog with rupicolous tadpoles from northern Zambia (Anura: Ptychadenidae)
(Magnolia Press, 2018)We describe a new species of Ptychadena from Mutinondo Wilderness in northern Zambia. It has rupicolous tadpoles that develop in a film of water. The species is distinguished on morphology, advertisement call and DNA ...
