The genus Trachelas from the Iberian Peninsula is revised. A new species, Trachelas ibericus from Spain, is described from both sexes, and the female of T. validus Simon 1884, an Iberian endemic, is described for the first time. Data are presented for the occurrence of T. canariensis Wunderlich 1987 and T. macrochelis Wunderlich 1992, formerly considered Canarian endemics, on the Iberian Peninsula. Trachelas praestans (O. Pickard-Cambridge 1911) is synonymized with Creugas gulosus Thorell 1878. Trachelas purus Kritscher 1969 is synonymized with T. rayi Simon 1878, and T. flavipes L. Koch 1882 with T. maculatus Thorell 1875. A diagnosis, descriptions, illustrations, distribution data, and a key are presented for the eight presently known Trachelas species of the Mediterranean region. In addition, an update is given on the presence of Cetonana laticeps (Canestrini 1868) in Spain.
