Twenty-one rissoid species have been found in four bathyal samples from the Strait of Sicily, represented exclusively by empty shells. Some of these species are shallow water dwellers, associated with algal facies, others are typical of deep-sea (bathyal-abyssal). Two species are described as new (Alvania ismar n. sp. and Manzonia schmidti n. sp.,...

A new species of the rissoid genus Alvania Risso, 1826 (Gastropoda Rissoidae) is described based on shells sorted out of a bioclastic sand sample collected with a trap box for Marginella species in Manda Toto Island (Lamu Archipelago, Kenya). It is compared with the most similar congeners.

The extant species of the genera Alvania Risso, 1826, Haurakia Iredale, 1915, Parashiela Laseron, 1956, Simulamerelina Ponder, 1985 and Subestea Cotton, 1944 (Rissoidae Gray, 1847) collected in the shallow waters of French Polynesia are herein revised, for a total of 19 species. Additionally, a new genus for a new deep-water species is here introdu...

Based on similarity in shell morphology, it is proposed that Alvania pluricosticillata Chirli & Forli, 2021 (fossil, recently described from the Plio-Pleistocene of Tuscany and Calabria) and Crisilla gagliniae (Amati, 1985) (extant, originally described from eastern Sicily) actually represent a single species. By priority, Crisilla gagliniae is the...

Pusia (Ebenomitra) angeloamatii, a new species of the genus Pusia Swainson, 1840 (Gastropoda Costellariidae), is described based on empty shells from the coasts of southern Turkey (Eastern Mediterranean Sea). It is compared with other species of the genus. Uromitra hypatiae Pallary, 1912 (currently Vexillum hypatiae) is transferred to Pusia based o...

The deep-water extant Rissoidae Gray, 1847 of the genera Benthonella Dall, 1889 and Benthonellania Lozouet, 1990 collected in French Polynesia are herein revised. Three species of Benthonella and eight of Benthonellania are described as new (all but one from French Polynesia): Benthonella boucheti n. sp., Benthonella basistriata n. sp., Benthonella...

The mollusc fauna of the Mediterranean Sea is still considered as the best-known marine mollusc fauna in the world. The previous modern checklists of marine Mollusca were produced by joint teams of amateurs and professionals. During the last years the Italian Society of Malacology (Società Italiana di Malacologia – S.I.M.) maintained an updated ver...

A new Mediterranean species of the genus Crisilla Monterosato, 1917 (Rissooidea, Rissoidae) is described: Crisilla hiera n. sp. All known specimens are empty shells retrieved from a sample of bioclastic sand collected in a submarine cave at Marettimo Island (type locality). It is compared with the most similar congeners from the Mediterranean Sea,...

115 sintipi, Z.M. Palermo) ci evidenzia, a conferma di ciò, carat-teri morfologici del tutto ricalcanti quelli della specie monte-rosatiana. Tuttavia la impossibilità di poter esaminare compa-rativamente la serie tipica di consociella con quella di lanciae (Dr. Gravina, com. personale, Z.M.R.), non ci consente di avvalorare questa nostra ipotetica...

Mesophotic assemblages are the next frontier of marine exploration in the Mediterranean Sea. Located below recreational scuba diving depths, they are difficult to access but host a diverse array of habitats structured by large invertebrate species. The Eastern Mediterranean has been much less explored than the western part of the basin and its meso...

Acanthochitona pilosa Schmidt-Petersen, Schwabe & Haszprunar, 2015, originally described from southern France, is here reported for the first time from Spain and Algeria. The specimens from Oran were attached on the shell of living Cymbula safiana (Lamarck, 1819), together with Lepidochitona monterosatoi Kaas & Van Belle, 1981. A. oblonga Leloup, 1...

A new Mediterranean species of the genus Alvania Risso, 1826 (Gastropoda Rissoidae) is de-scribed: 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. settepas-sii Amati et Nofroni, 1985, with which it is sympatric, and A. schwartz...

Herein we revise several Recent Mediterranean species of the rissoid genus Alvania Risso, 1826: Alvania scabra (Philippi, 1844), Alvania sculptilis (Monterosato, 1877), Alvania sororcula Granata-Grillo, 1877, Alvania lucinae Oberling, 1970, Alvania josefoi Oliver & Templado, 2009 and Alvania scuderii Villari, 2017. They represent a rather homogeneo...

Some taxonomically troublesome nominal taxa of the rissoid genus Alvania Risso, 1826 are examined: Alvania disparilis Monterosato, 1890, A. peloritana (Aradas & Benoit, 1874), A. perversa F. Nordsieck, 1972 and A. dorbignyi (Audouin, 1826). The four species are here considered as valid, and for the sake of nomenclatural stability lectotypes of Alva...

We have compiled a complete list of new marine molluscan taxa introduced by Tommaso Allery Di Maria, Marquis of Monterosato (1841–1927). The dates of publication of every single work have been checked against available evidence, and an updated bibliography is also presented. Finally, the type material of all marine taxa expected to be in the collec...

KEY WORDS

The Mediterranean species of the genus Mitromorpha Carpenter, 1865 as currently conceived, are herein reviewed. The genus is represented in the Mediterranean Sea by eleven species, of which seven are here described as new, all included conservatively in the subgenus Mitrolumna Bucquoy, Dautzenberg & Dollfus, 1883: Mitromorpha (Mitrolumna) columbell...

KEY WORDS The taxonomy of species of the family Rissoidae has always been source of debate and only a few of rissoid genera have been recently comprehensively revised. The need of revisional work is particularly obvious in the case of the genus Crisilla Monterosato, 1917, taxon showing open nomenclatural issues along with uncertainty and difficulty...
