 abstract={In this contribution we revise the ammonite subgenus Pervinquieria (Styphloceras) van Hoepen, 1951, and show it to be a synonym of Pervinquieria sensu stricto. All of the species assigned to the subgenus by van Hoepen are interpreted as a single variable species, of which Pervinquieria (Collignonia) vallifera van Hoepen, 1951, is a further synonym.},
