Trachylepis
Trachylepis·Scincidae
Trachylepis is a genus of skinks primarily found in Africa, belonging to the subfamily Mabuyinae. The name "Trachylepis" translates to "rough-scaled," reflecting the characteristic keeled dorsal scales found in most species, despite their superficially smooth appearance. This genus encompasses a diverse group of lizards, including species with various common names and habitats across the African continent and even extending to islands like Fernando de Noronha in Brazil.

About Trachylepis
Trachylepis: The Rough-Scaled Skinks
Trachylepis is a genus of skinks belonging to the subfamily Mabuyinae, with its members primarily inhabiting the African continent. The genus name itself, "Trachylepis," translates to "rough-scaled," a descriptor that aptly suits most species within this group. Despite a superficially smooth appearance, these skinks are characterized by having three or more subtle longitudinal keels on their dorsal scales, contributing to their distinctive texture.
Historically, many Trachylepis species were once classified under the broader "wastebin taxon" Mabuya, and for a period, were placed within Euprepis. Today, Trachylepis is recognized as a distinct clade comprising Afro-Malagasy mabuyas. Interestingly, the genus also includes species found beyond Africa, such as Trachylepis atlantica from the Brazilian island of Fernando de Noronha. Evidence suggests that the ancestors of T. atlantica likely crossed the Atlantic Ocean from Africa within the last nine million years. The genus may also extend to mainland South America with lesser-known species like Trachylepis tschudii and Trachylepis maculata.
The diversity within Trachylepis is reflected in the numerous species recognized, each with its own common names and specific ecological niches across various African landscapes. Studies have been conducted to classify and understand the relationships within this genus, leading to the refinement of its taxonomic boundaries and the identification of its evolutionary pathways.

Frequently Asked Questions
What does the name Trachylepis mean?
The generic name Trachylepis literally translates to "rough-scaled." This name refers to the characteristic feature of most species in this genus, which have three or more slight longitudinal keels on their dorsal scales, giving them a rougher texture.
Where are Trachylepis skinks primarily found?
Trachylepis skinks are mainly found across the African continent. However, the genus also includes species found on islands such as Fernando de Noronha off the coast of Brazil.
What is the taxonomic classification of Trachylepis?
Trachylepis belongs to the skink family and is classified within the subfamily Mabuyinae. It was previously included in the broader "wastebin taxon" Mabuya.
Are there any Trachylepis species found outside of Africa?
Yes, Trachylepis contains a species, T. atlantica, from the Brazilian island of Fernando de Noronha. There is also a possibility of occurrence in mainland South America with species like T. tschudii and T. maculata, though these are less well-documented.
What is the defining physical characteristic of Trachylepis skinks?
The most defining physical characteristic, indicated by their name, is their "rough-scaled" appearance. This is due to the presence of multiple slight longitudinal keels on their dorsal scales, even though they may appear smooth at first glance.
