Taxonomie und Systematik der HippocardioideaPojeta & Runnegar, 1976 [n. superfam.] (Mollusca; Rostroconchia)

The revisions of the families PseudobigaleaidaeHoare, Mapes &; Yancey, 2002 and HippocardiidaePojeta &; Runnegar, 1976 led to the introduction of a new taxon at the superfamily rank in order to unite the two families and distinguish them from the members of the Conocardiidae and Bransoniidae within the order Conocardiida. The autapomorphy of this new superfamily HippocardioideaPojeta &; Runnegar, 1976 [n. superfam.] — the more or less uniform development of at least one hood — is considered taxonomically as so important that we exclude a common ancestry of the almost contemporaneously occurring taxa of the Hippocardiidae, Pseudobigaleaidae on the one hand and the Bransoniidae sensuPojeta &; Runnegar on the other. The family Hippocardiidae is divided into six taxa on subfamily rank, the HippocardiinaePojeta &; Runnegar, Babinicardiinae n. subfam., Barrandeicardiinae n. subfam., Bohemicardiinae n. subfam., Goticardiinae n. subfam. and Hassiacardiinae n. subfam. At the species level, 13 taxa are assigned to the generaBabinicardia n. gen.,Barrandeicardia n. gen.,Bohemicardia n. gen.,Filicardia n. gen,.Globocardia n. gen.,Goticardia n. gen.,Pohlia n. gen. andHassiacardia n. gen. Additionally, the speciesGoticardia kauffmannii n. gen. n. sp. is introduced, whereas the primary homonymy of ?Conocardium“reticulatum Babin, 1966 is retained, because this taxon remained inassignable to any of the existing genera, but is considered as a member of the Hippocardiidae. The revised family Hippocardiidae occurred stratigraphically from the Middle Silurian (Wenlockian) until Mississippian time; members of the new superfamily Hippocardioidea are known from the Ordovician until the Pennsylvanian.
