| Abstract |
Subject of this note is a reappraisal of Coeloma isseli Ristori, 1886 from the Pliocene of San Venanzio (Modena, Emilia-Romagna, Italy) based upon the type series, including only the specimens housed in the Museo di Storia Naturale di Firenze, as reported by Ristori himself. Although the studied specimens have a poor state of preservation of the front and anterolateral margins, some characters, such as the shape of carapace, the orbits, the supra-orbital margin, the epibranchial regions, and the shape of the thoracic sternum, are shared with Geryon Krøyer, 1837 (Geryonidae Colosi, 1924) to which we tentatively assigned the species Coeloma isseli. Therefore, the new combination Geryon isseli (Ristori, 1886) is herein proposed. Finally, a comparison with the other genera of the family is herein provided. |
