The examination of type and non-type specimens and of original descriptions for several nominal species of the genus Solea allowed me to determine that among the 97 nominal species, only eight species are valid. They are Solea solea, S. senegalensis, S. aegyptiaca, S. turbynei, S. ovata, S. stanalandi, S. elongata and S. heinii. I provide a new description for the genus with comments on its phylogenetic position, and a new description for each species. I also resurrect the genus Barnardichthys Chabanaud, 1927b for the species Solea fulvomarginata Gilchrist, 1904. I provide an identification key to species of Solea.
The second part of the work is a revision of the genus Dagetichthys Stauch and Blanc, 1964, including the species that were traditionally described as Synaptura sensu Chabanaud, 1928, with a description and the phylogeny of these species. I first determined that the five species in the genus Synaptura sensu Chabanaud, 1928, were forming a monophyletic group with Dagetichthys lakdoensis as its sister group. As Synaptura has never been a valid genus name, I assigned the Synaptura sensu Chabanaud, 1928, species to the genus Dagetichthys. Its sister group is Buglossidium luteum (Risso, 1810). From the most plesiomorphic to the most apomorphic, the species are D. lakdoensis Stauch and Blanc, 1964, D. marginatus Boulenger, 1900, D. lusitanicus Brito Capello, 1868, D. commersonnii (Lacepede, 1802), D. albomaculatus Kaup, 1858, and D. cadenati Chabanaud 1948. I discuss a biogeographic scenario explaining the distribution of species and I give an identification key to species.
