Status Fischer (1969) listed the name as senior synonym of Symmetrocapulus semirugosus (Laube), considering it a nomen nudum ("insuffisamment caractérisé"). It is, however, available and may take priority, but future studies (Gründel 2012) did not consider it. D'Orbigny's (1850) description is indeed short and little informative. [details]
