| Resumo: |
A new troglobitic genus and species, viz. Speleodentorcula beroni gen. & spec. nov., is described from the island of Euboea, Greece. The species, known from a single cave only, is quite isolated systematically. According to the structure of its shell and the genitalia S. beroni should be classified with the Orculidae. Within this family Speleodentorcula is most similar to Walklea anatomically; conchologically there is some vague resemblance to Fauxulus (apertural denticles) and Odontocyclas, Walklea, Fauxulus and Afriboysidia (surface sculpture). Speleodentorcula alone is considered the sister group of the taxon encompassing these last mentioned four genera.
