Remarks.

Sphyradium dobrogicum was described based on a single shell. The holotype could not be located in the collection of the Grigore Antipa National Museum of Natural History (Bucharest) during a recent search (2012). It could still be in Grossu’s house (Oana Popa, pers. comm., 2011) but, at present, the holotype seems to be lost.

Bank (2011) and Welter-Schultes (2012) assigned the species to Orcula without supporting evidence. Sphyradium dobrogicum has a domed apex, a ribbed shell and very weak lamellae (see original description and drawing), indicating that it may represent a dwarf specimen of Sphyradium doliolum . We visited the type locality of Sphyradium dobrogicum in 2011 but found only Sphyradium doliolum .

Based on available information we suggest using Sphyradium dobrogicum as a synonym of Sphyradium doliolum .
