    First record of Callistochiton pachylasmae (Monterosato, 1879) for the Adriatic Sea (Polyplacophora Callistoplacidae)

    ABSTRACT
    It is reported the first record of Callistochiton pachylasmae (Monterosato, 1879) for the Adriatic Sea. It a very rare and peculiar polyplacophoran species (Callistoplacidae Pilsbry, 1893). Actually, The few known records span a wide Mediterranean range and extend to the neighbouring Atlantic.

    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.

    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.

    ABSTRACT
    A new Mediterranean species of the genus Alvania Risso, 1826 (Gastropoda Rissoidae) is described: A. rominae n. sp. All examined specimens are from the Ionian Sea. It is compared with the most similar congeners from the Mediterranean Sea: A. lineata Risso, 1826 and A. settepassii Amati et Nofroni, 1985, with which it is sympatric, and A. schwartziana Brusina, 1866, A. elisae Margelli, 2001, A. bartolinorum Amati et Smriglio, 2019 and A. zaraensis Amati et Appolloni, 2019.
