An updated list of echinoderm groups and species, which have been described, verified or newly ascertained from the Lochkovian, Lochkov Formation (Lower Devonian of the Barrandian area), is presented for the first time. The list is arranged in the form of a table with a brief introduction about the character of the echinoderm assemblages and their palaeoecology in both facies of the Lochkovian, i.e. the Radotín Limestone and Kotýs Limestone. In the systematic part, a new type of ophiocistioid goniodonts discovered in the Kotýs Limestone is described and a new taxon, Branzoviella talpa gen. et sp. n. (Ophiocistioidea, Echinodermata), is set for it.
