With a wide geographic sampling comprising more than 90 localities and including more than 180 individuals, we conducted species delimitation analyses with a Maximum Likelihood approach that uses a mixed Yule-coalescent model to detect species boundaries. We estimated molecular phylogenetic relationships employing Maximum Likelihood and Bayesian Inference methods using mitochondrial and nuclear sequences. We conducted divergence time analyses using a relaxed clock model implemented in BEAST. Our results recovered twelve species that form 4 groups: Lycosa tarantula group comprising L. tarantula the type species of the genus, L. hispanica and L. bedeli; Lycosa oculata group composed of L. oculata, L. suboculata and three putative new species; Lycosa baulnyi group formed by the maghrebian L. baulnyi and L. vachoni and Lycosa fasciiventris group that includes two widespread species, L. fasciiventris and L. munieri. We found that each group of species shows a characteristic burrowing behaviour and molecular and morphological diagnostic characters. Molecular clock analyses support the hypothesis of a relatively recent evolutionary origin of diversification of the group (4.96 Mya (3.53-6.45 Mya)). The establishment of the Mediterranean-like climate and the Pleistocenic glacial cycles seem to have been the main factors that promoted the diversification within the group. Finally, the results obtained in this study together with the revision of museum specimens, descriptions, redescriptions and illustrations, lead us to propose 18 nomenclatural changes (synonymies, generic transfers and nomina dubia) concerning the genera Lycosa, Allocosa and Hogna in the Western Mediterranean.} }
