A summary is given of the species-level names in the genus Iberus, the representatives being endemic for Spain. Noteworthy results are: obversa has to be attributed to Born, 1778 (not 1780); guiraoana has to be attributed to Pfeiffer, 1853 (not Rossmaessler, 1854); carthaginiensis has to be attributed to Rossmässler, 1853 (not 1854); loxana has to be attributed to Schmidt, 1853 (not Rossmaessler, 1854); the author of campesina is not Ezquerra as often quoted, but Pfeiffer 1846; the lectotype selection of guiraoana, loxana and alcarazana by Martínez-Ortí & Robles (2012) is invalid. For guiraoana the lectotype is reselected. The holotype of laurenti and a syntype of partschi is figured. A nomenclatural overview is given of the hitherto recognized (sub)species of Iberus as delineated by the molecular studies of Elejalde and co-workers (2008).
