Titiotus Simon is revised, and contains at least 16 species known only from California. Males of the type species, T. californicus Simon, are described for the first time, as are those of T. flavescens (Chamberlin and Ivie). Eusparassus hansii Schenkel is transferred from the Sparassidae to Titiotus, and its male is newly described. Thirteen new species are described.
