A new species of thick-toed gecko (Pachydactylus) from Serra da Neve and surrounding rocky areas of southwestern Angola (Squamata: Gekkonidae)

Abstract

Several specimens of Pachydactylus angolensis, a poorly known Angolan endemic gecko, have recently been collected in southern Angola, considerably increasing its known distribution range. Previous observations led to the hypothesis that two different morphological forms exist in the country—a coastal form and an inland form. Based on the morphological examination of historical and recently collected specimens, as well as on newly generated molecular data, we conducted a taxonomic revision of this putative species complex. The results support the separation of these two forms as two different species. The coastal form belongs to the nominotypic population, while the inland form is here described as a new species, Pachydactylus maiatoi sp. nov.. A brief comment on the biogeographical implications of this discovery is also provided.
