A list of earthworm species recorded in the Iberian Peninsula, based on examination of the literature and collections, is presented. Species which have been recorded in only one paper, or of which we have not been able to study Iberian material, are listed separately. With the collected data a map has been prepared from which the regions' studied and those which need to be sampled to complete the study of the Iberian Peninsula, principally Mediterranean zones, can be appreciated. Some provisional biogeographic considerations are presented. The Eurosiberian Region is represented in the North; its fauna is of Central-European character and it is possible to differentiate two zones, “Basque-Pyrenaic” and “Galaico-Lusitanian”. In the Mediterranean Region some species of Lumbricus and Dendrobaena are absent or scarce, and there are some differences between the Superprovinces “Mediterranean-Iberian-Levantine” with Hormogaster species and “Mediterranean-Iberian-Atlantic” with the Allolobophora molleri complex.
