D. pictus is found in portions of North Africa as well as some European western Mediterranean areas. Countries of native occurrence include Algeria, Tunisia, France, Italy and Malta (Bosch et al. 2009). In Italy one of the main ecoregions of occurrence is the South Appenine mixed montane forests. The Mediterranean woodlands and forests is one of the chief ecoregions of occurrence in North Africa (World Wildlife Fund & Hogan, 2007).
Prior to the recognition of D. scovazzi as a separate species, the distribution of D. pictus included the Galita Islands (Salvador, 1996). It is not clear whether the population on the Galita Islands is D. pictus or D. scovazzi.
