In this study we compile data regarding lizard densities of the island populations of the Ibiza wall lizard, Podarcis pityusensis, which can serve as a baseline for future research and control of the invasive snakes, and in particular the horseshoe whip snake Hemorrhois hippocrepis, in the Pityusic Islands. Special attention has been given to the correct official spelling of 96 locations of which 89 are real rocks, islets and islands. For each island a short description, toponymy, faunal and floral aspects and some herpetological history is given, and a lizard density value was assigned. The results are very disturbing, with two confirmed- and three most likely extinct island populations of Podarcis pityusensis, and we call for coordinated action.

The Maltese Wall Lizard Podarcis filfolensis has long fascinated biologists due to its remarkable phenotypic plasticity and island-specific traits. Historically, the species was divided into multiple subspecies based on morphology, a framework that persisted unchallenged for most of the 20th century. However, contemporary genetic studies undermine the subspecies model, instead revealing two major clades across the Maltese and Pelagian Islands. This paper reviews historical and modern taxonomic interpretations, presents detailed morphological field observations, and critiques the persistent misuse of outdated subspecies nomenclature in both academic and public discourse. We advocate for the recognition of island morphs within a single species model and call for institutional leadership in taxonomic modernization.
