Jg. 36 H. 3/4 S. 577—584 Bonn, Oktober 1985 Some interrelationships of the Canary Island lizards of the genus Gallotia by Thorpe, K. Watt & M. Baez Introduction In the Canary islands there are, depending on the author, three or four extant nominal species of the endemic genus Gallotia, i. e. the large simonyi and steh- lini, the typically 'medium' sized galloti and the typically 'small' atlántica. Their distribution and differentiation is of interest. Every island and substantial islet is occupied yet the level of sympatry between extant populations is extremely low, that is, the remaining small population of simonyi simonyi is sympatric with galloti and the population of stehlini on Gran Canaria may be sympatric with a small, possibly introduced, population of atlántica (Barquín & Martín 1982). Nevertheless the distribution of atlántica and galloti is completely mutually 100 km. 18° 17° 16° 15° 14° 13° Fig. 1. Distribution of extant populations of Gallotia and locality samples. G. galloti (solid squares) is widespread in La Palma (P), North East Tenerife (NET), South Tene- rife (ST), Gomera (G) and Hierro (H). G. atlántica is widespread (solid triangles) in Ale- granza (A), Graciosa (GR), Montana Clara (MC), Lanzarote (LA), Lobos (LO) and Fuer- teventura (F) and is reported to have a small population (open triangle) on Gran Cana- da (GC). The large lizard, G. stehlini is widespread on Gran Canaria (solid circle) and a small population of G. simonyi still (open circle) exists on Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Zoologisches Forschungsinstitut und Museum Alexander Koenig.
