Phosphatic fossils from the upper Pliensbachian Pleuroceras spinatum ammonite Zone of Buttenheim (Bavaria, southern Germany), identified previously as scyphopolyps and named Liapora neubigi by Keupp (2019), are demonstrated to be the capitular valves of a phosphatic barnacle that had been described as Pollicipes(?) lotharingica by Méchin in 1901 from an identical level at Agincourt (Meurthe-et-Moselle, northeastern France). The new material, representing only the second record of the species and the first discovery of the scutum, is described and the genus Liapora Keupp, 2019 is reassigned to the Eolepadidae Buckeridge, 1983. The diagnoses of the other two genera of eolepadids, Eolepas Withers, 1928 and Toarcolepas Gale & Schweigert, 2015 are revised in the light of the new discoveries, and the assignation of species to the three genera is discussed. Eolepadids are a low-diversity group of cirripedes which occur sporadically from the Triassic (Rhaetian) to the Lower Cretaceous (Berriasian) and represent the sister group to all calcite-shelled forms.
