    Description of a new species of the genus Trophonopsis Bucquoy et Dautzenberg, 1882 (Gastropoda Muricidae Pagodulinae) from the Mediterranean Sea
    Proceedings of the Eighth Malacological Pontine Meeting, October 4th-5th, 2014 - San Felice Circeo, Italy

    ABSTRACT
    Based on shell characters, a new species of the gastropod family Muricidae, Trophonopsis sparacioi n. sp., from Mediterranean Sea is described. Shells of the new taxon were collected from bathyal bottoms, in the Tyrrhenian Sea. The new taxon is compared with others species of the genus Trophonopsis Bucquoy et Dautzenberg, 1882, occurring in northeastern Atlantic and Mediterranean Sea.

    Additional notes on the systematics and new records of East Atlantic species of the genus Sorgenfreispira Moroni, 1979 (Gastropoda Mangeliidae)
    Proceedings of the Eighth Malacological Pontine Meeting, October 4th-5th, 2014 - San Felice Circeo, Italy

    ABSTRACT
    The Recent species currently ascribed to the Bela brachystoma-complex, Gastropoda Mangeliidae, (i.e.: Bela brachystoma (Philippi, 1844); Bela africana Ardovini, 2004; Bela ardovinii Mariottini et Oliverio, 2008; Bela exilis (Ardovini, 2004) should better be allocated in the genus Sorgenfreispira Moroni, 1979. Based on numerous samples, the distribution of the Recent species is summarised. Sorgenfreispira brachystoma (Philippi, 1844) comb. nov. ranges from Scandinavia to southern Morocco. Sorgenfreispira africana (Ardovini, 2004) comb. nov. is first recorded from Western Sahara, Ivory Coast, Angola and Ghana; Sorgenfreispira ardovinii (Mariottini et Oliverio, 2008) comb. nov. is first recorded from Ivory Coast; S. exilis (Ardovini, 2004) comb. nov. is first recorded from Mauritania, Western Sahara, Ivory Coast, Angola. Based on the study of the type material, Bela brachystoma apicalis Nordsieck, 1977, was actually based on specimens of B. taprurensis Pallary, 1904. Bela taprurensis is here first recorded from Libya.

    Phenotypic diversity, taxonomic remarks and updated distribution of the Mediterranean Jujubinus baudoni (Monterosato, 1891) (Gastropoda Trochidae)

    ABSTRACT
    Jujubinus baudoni (Monterosato, 1891) shows highly diverse chromatic and morphological patterns. Based on the examination of the type material and series of specimens from private collections, and of recent findings from Sardinia, we reviewed and updated the distribution of this species, and figured the three representative shell colour morphs which are constant in local populations. A comparative SEM analysis did not outline significant differences among shells with greatly different colour patterns, thus justifying their belonging to a single specific entity. The survey of the material of J. baudoni did not show a strict correspondence between Corse and Sardinian shell colour morphs and their geographical distribution, not allowing to clearly state trends and relationships among island populations. On the contrary the colour pattern of the continental shells of J. baudoni seems to be constant and different from the ones of the island shells, indicating a well separated colour morph. This study confirmed that the distribution of J. baudoni is limited to the north-western Mediterranean Sea, with its eastern range widened to the La Maddalena Archipelago (Sardinia). The record of this species from Azores is due to a misidentification with J. pseudogravinae Nordsieck, 1973, which is also figured for comparison. A lectotype and paralectotypes of Trochus baudoni are herein designated.
