Sclerocephalus - Taxonomy

Taxonomy

Krätschmer (2004) questioned the validity of the type species Sclerocephalus haeuseri, of which the holotype is lost, and considered Pfarrwaldia jeckenbachensis as valid name for the neotype designated by Boy (1988). This was refuted in the revision of Schoch & Witzmann (2009), who considered P. jeckenbachensis as younger synonym of S. haeuseri.

The following four species are recognized as valid by Schoch & Witzmann (2009):

• Sclerocephalus haeuseri Goldfuss, 1847 from the Asselian (Lower Rotliegend) of Rhineland-Palatinate in Germany.
• Sclerocephalus bavaricus (Branco, 1887) from the Asselian (Lower Rotliegend) or uppermost Pennsylvanian (Gzhelian) of Rhineland-Palatinate in Germany.
• Sclerocephalus jogischneideri Werneburg, 1992 from the Asselian (Lower Rotliegend) of Thuringia in Germany
• Sclerocephalus nobilis (Krätschmer & Resch, 2005) from the Asselian (Lower Rotliegend) of Rhineland-Palatinate in Germany.
