A review of the species of the order Cocculiniformia and the family Lepetidae (Gastropoda: Archaeo-gastropoda) from the Iberian coasts is presented. The shell, radula and external morphology of the living animal of seven species of Cocculiniformia (Cocco-pigya spinigera, C. viminensis, Lepetella espinosae n. sp., L. sierrain. sp., L. barrajonin. sp., Copulabyssia corrugata and Addisonia excentrica) and one lepetid (Propilidium exiguum) are described. The shell of Lepetella ionica is also described, and its generic position is discussed. It is concluded that shell features are not sufficient to differentiate living species of Lepetella, and therefore the name Lepetella laterocompressa (Rayneval, Van den Hecke & Ponzi, 1854) should be restricted to the Pleistocene fossil species of Monte Mario. Seven species of Cocculiniformia are recorded for the first time for the Iberian fauna. The name Addisonia excentrica Tiberi, 1857, is proposed as the correct name for Gadinia lateralis Réquien, 1848, which is considered a junior synonym of Trimusculus mammilaris (Linné, 1758), and Addisonia paradoxa Dall, 1882 is a junior synonym of A. excentrica. Cocculina conspersa Dautzenberg & Fischer, 1897 is considered a synonym of Coccopigya spinigera (Jeffreys, 1883), and Propilidium scabrosum Jeffreys, 1883 of P. exiguum (Thompson, 1844). Ten other species of Cocculiniformia and six Acmaeoidea are mentioned and discussed on the basis of old descriptions or records from neighbouring zones, and the new genus Bogia is proposed for Cocculina labronica Bogi, 1984. The geographic and bathymetric ranges of all the species are given, and some aspects of their biology, taxonomy and biogeography are discussed.
