Ptychadena is a genus of frogs in the grassland frog family, Ptychadenidae. [1] [2] They are distributed in Sub-Saharan Africa, as well as nilotic Egypt. The common names of this genus are ridged frogs and grass frogs. [1] This type of family have many different characteristics such as the species, Ptychadena neumanni who have long hindlimbs and a large ear drum compared to the Ptychadena erlangeri, for example. [3] They also have a unique bone structure which is a fusion between the presacral vertebrae and sacrum. [4]

The genus Sphenomorphus – vernacularly known as the common skinks – currently serves as a "wastebin taxon" for numerous skinks. While most or all species presently placed here are probably rather close relatives, the genus as presently delimited is likely to be not monophyletic and is in need of review. Some species in this genus have been moved to Pinoyscincus.

<i>Trachylepis</i> Genus of lizards

Trachylepis is a skink genus in the subfamily Mabuyinae found mainly in Africa. Its members were formerly included in the "wastebin taxon" Mabuya, and for some time in Euprepis. As defined today, Trachylepis contains the clade of Afro-Malagasy mabuyas. The genus also contains a species from the Brazilian island of Fernando de Noronha, T. atlantica, and may occur in mainland South America with Trachylepis tschudii and Trachylepis maculata, both poorly known and enigmatic. The ancestors of T. atlantica are believed to have rafted across the Atlantic from Africa during the last 9 million years.
