    First record of fossil Jujubinus curinii Bogi et Campani, 2006 (Gastropoda Trochidae) in north-eastern Sicily (Italy)

    ABSTRACT
    The discovery of a fossil specimen of Jujubinus curinii Bogi et Campani, 2006 (Gastropoda Trochidae) is reported from the geologic stage of “Milazziano” (Tyrrhenian, Pleistocene) located at Capo Milazzo, North-Eastern Sicily. The specimen has been found during a study on the Jujubinus Monterosato, 1884 material stored in the Monterosato’s collection at the Museo Civico di Zoologia of Rome, Italy.

    Check-list of the Nudibranchs (Mollusca, Gastropoda) from the biodiversityhot spot “Scoglio del Corallo” (Argentario promontory, Tuscany)

    ABSTRACT
    The Mediterranean nudibranch (Mollusca Gastropoda) fauna is part of complex communities belonging to the Mediterranean endemic “Coralligenous”. This important ecosystem shows a high species richness and functional diversity with assemblages of species tied together by major trophic and ecological relationships. A first check-list for the biodiversity hot spot “Scoglio del Corallo”, located along the coast of the Argentario promontory (Tuscany, Tyrrhenian Sea) is here reported.

    Jujubinus errinae n. sp. (Gastropoda Trochidae) from the Strait of Messina, Mediterranean Sea

    ABSTRACT
    A new species of the gastropod family Trochidae, Jujubinus errinae n. sp., from the Mediterranean Sea is described based on shell characters. The new taxon was compared with the most closely related species showing marked sculpture and from relatively deep water habitat, J. catenatus Ardovini, 2006, J. montagui (Wood, 1828) and J. tumidulus (Aradas, 1846). The species, which is known from the type locality only, the Strait of Messina, might be strictly associated to the endemic hydrocoral Errina aspera (Linnaeus, 1767) beds (Hydrozoa Stylasteridae).

    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 of Thuridilla hopei (Vérany, 1853) (Gastropoda Heterobranchia Sacoglossa). A DNA-barcoding approach
    Proceedings of the Seventh Malacological Pontine Meeting, October 5th-6th, 2013 - San Felice Circeo, Italy

    ABSTRACT
    The sacoglossan Thuridilla hopei (Vérany, 1853) shows highly diverse chromatic patterns. Based on the morphological examination of specimens from different Mediterranean localities, we have observed that in spite of this great variability in colours of T. hopei, two major chromatic morphotypes are related to bathymetry. Specimens from deeper water exhibit blue darker and more uniform patterns than individuals from shallower water, which show a more variable, dashed and spotted arrangement of light blue, yellow, orange, white and black pigmentation. A molecular genetic analysis using the mitochondrial COI and 16S rDNA markers has confirmed that all these extremely different chromatic morphotypes belong to a single specific entity, i.e. T. hopei, a sacoglossan with a wide distribution, from Macaronesia in the Atlantic, to the easternmost Mediterranean Sea.

    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.

    Report of Coralliophila guancha Smriglio, Mariottini et Engl, 2003 in the Mediterranean Sea (Gastropoda Muricidae)
    https://doi.org/10.31396/Biodiv.Jour.2023.14.4.707.711

    ABSTRACT
    With this note the status and distribution of Coralliophila guancha Smriglio, Mariottini et Engl, 2003 (Gastropoda Muricidae) are assessed, based on published and unpublished records. The range of the species is extended to the Mediterranean Sea, where it had previously been recorded as a distinct species, Coralliophila ahuiri Cossignani, 2009, which is here regarded as a synonym.
