New Pygmy Gecko (Goggia: Gekkonidae) from the arid Northern Cape Province of South Africa

The genus Goggia is composed of ten small bodied leaf-toed gecko species endemic to South Africa and adjacent Namibia. Using a combination of phylogenetic and morphological analyses we assessed the taxonomic status of an isolated rupicolous population discovered south of Klein Pella in the Northern Cape Province of South Africa. The newly collected material was recovered as a well supported clade by two independent phylogenetic algorithms (maximum likelihood and Bayesian inference), with little intraspecies structuring.

While the particular interspecific relationships among closely related Goggia remain unresolved, the phylogenetic results suggest the novel material is related to G. rupicola, G. gemmula, G. incognita and G. matzikamaensis. This is supported by the similar ecologies (rupicolous lifestyle), geographies (arid western extent of South Africa) and morphologies (prominent dorsal chevrons and yellow-centred pale dorsal spots), which are shared among these closely related species.

Despite their similarity, the novel population from Klein Pella remains geographically separate, differs from congeners by an uncorrected ND2 p-distance of 11.03–22.91%, and is morphologically diagnosable. Based on these findings we describe the Klein Pella population as a new species.
