Data from: Disentangling the Pelomedusa complex using type specimens and historical DNA (Testudines: Pelomedusidae)

Uwe Fritz, Alice Petzold, Christian Kehlmaier, Carolin Kindler, Patrick Campbell, Margaretha D. Hofmeyr & William R. Branch
Recent research has shown that the helmeted terrapin (Pelomedusa subrufa), a species that occurs throughout sub-Saharan Africa, in Madagascar and the southwestern Arabian Peninsula, consists of several deeply divergent genetic lineages. Here we examine all nominal taxa currently synonymized with Pelomedusa subrufa (Bonnaterre, 1789) and provide mitochondrial DNA sequences of type specimens or topotypic material for most taxa. Lectotypes are designated for Testudo galeata Schoepff, 1792, Pentonyx capensis Duméril & Bibron, 1835, Pelomedusa nigra Gray,...

Data from: A revision of African helmeted terrapins (Testudines: Pelomedusidae: Pelomedusa), with descriptions of six new species

Alice Petzold, Mario Vargas-Ramírez, Christian Kehlmaier, Melita Vamberger, William R. Branch, Louis Du Preez, Margaretha D. Hofmeyr, Leon Meyer, Alfred Schleicher, Pavel Široký & Uwe Fritz
Using nearly range-wide sampling, we analyze up to 1848 bp of mitochondrial DNA of 183 helmeted terrapins and identify a minimum of 12 deeply divergent species-level clades. Uncorrected p distances of these clades equal or clearly exceed those between the currently recognized species of Pelusios, the genus most closely related to Pelomedusa. We correlate genetic discontinuities of Pelomedusa with data on morphology and endoparasites and describe six new Pelomedusa species. Moreover, we restrict the name...

Data from: A single origin of extreme matrotrophy in African mabuyine skinks

Margarita Metallinou, Jeffrey L. Weinell, Benjamin R. Karin, Werner Conradie, Philipp Wagner, Andreas Schmitz, Todd R. Jackman & Aaron M. Bauer
Most mammals and approximately 20% of squamates (lizards and snakes) are viviparous, whereas all crocodilians, birds and turtles are oviparous. Viviparity evolved greater than 100 times in squamates, including multiple times in Mabuyinae (Reptilia: Scincidae), making this group ideal for studying the evolution of nutritional patterns associated with viviparity. Previous studies suggest that extreme matrotrophy, the support of virtually all of embryonic development by maternal nutrients, evolved as many as three times in Mabuyinae: in...
