The name Vasconaster was proposed as a replacement name for the preoccupied Sarsella. According to Lambert & Thiery (1921) it is distinguished from Lovenia by the lack of internal ampullae and by its fully tuberculate plastron. The sternal plates of the type species, however, are not fully tuberculate, and there seem no grounds for separating this taxon from Lovenia, a view also held by Mortensen (1951).
