Molecular systematics of the wolf spider genus Lycosa (Araneae: Lycosidae) in the Western Mediterranean Basin

► Is the first comprehensive hypothesis for the phylogenetic relationships of genus Lycosa. ► Molecular species delimitation provides support for 12 different species. ► North-Western Africa has acted as the diversification center. ► Mediterranean-like climate and glaciations are the main factors of diversification. ► Important taxonomic changes are proposed.
