Resum: S’han localitzat diversos exemplars de sargantana italiana (Podarcis sicula) en un viver de jardineria dins el terme municipal de Sant Celoni (Vallès Oriental, Barcelona). Els especímens semblen del morfotipus meridional (“sicula”, reticulat, present a Sicília, Sardenya, sud d’Itàlia, Menorca i Dubrovnik). Una curta seqüència del gen mitocondrial 12S d’un individu corrobora la procedència geogràfica de la sargantana. D’altra banda, els responsables del viver han confirmat l’origen calabrès de les oliveres, dins de les quals haurien trobat refugi les sargantanes. En el mateix garden s’ha observat, en oliveres procedents d’Extremadura, exemplars de Timon lepidus i de Tarentola mauritanica, d’origen incert.
Abstract: Several specimens of Italian wall lizard (Podarcis sicula) were found in a garden center in Sant Celoni (Vallès Oriental, Barcelona). The specimens can be confidently assigned to the Italian meridional morphotype (“sicula” type, reticulated and present in Sicily, Sardinia, southern Italy, Menorca and Dubrovnik). A short sequence of the 12S rRNA mitochondrial gene from one specimen supports this hypothesis. The lizards arrived inside old olive trees imported from Calabria. In the same garden several specimens of Timon lepidus and Tarentola mauritanica of uncertain origin have been found in olive trees imported from Extremadura (South eastern Spain).

Fig. 4 (upper) & Fig. 5 (bottom): Bottom and Upper photo, olive trees imported to Sant Celoni’s
garden center (Catalunya), originating from Extremadura (South eastern Spain), in which it is
possible to see (enlarged photo at the bottom) one Timon lepidus (about three observed at the same
place) of unknown origin. Some individuals of Tarentola mauritanica have been seen on the same
tree, and it is possible that some of them come from Italy or South Spain. Genetic samples should be
analyzed in order to confirm these hypothetical introductions.
