New records of alien and cryptogenic marine bryozoan, mollusc, and tunicate species in Libya
No full textNew records of alien and cryptogenic invertebrate marine species in Libya are reported here based on field surveys conducted from June to November 2018, in a shallow bay next to the city of Tripoli. Those identified here include the cerithiid gastropod Cerithium scabridum Philippi, 1848, the goniodoridid sea slug Okenia longiductis Pola, Paz-Sedano, Macali, Minchin, Marchini, Vitale, Licchelli and Crocetta, 2019, the “spaghetti bryozoan” Amathia verticillata (delle Chiaje, 1822), and the ascidian Symplegma brakenhielmi (Michaelsen, 1904)

Clausilia costata var. subcostata Bellini 1908
No full textClausilia costata var. subcostata Bellini, 1908a: 14 [ex Tiberi ms.] Type locality: Ischia Island (Naples, Italy). Original description: “stries peu visibles” [more visible striae—with respect to an unknown clausilid, reported as Clausilia costata Ziegler]. Remarks: having been instituted on the basis of insignificant morphological characteristics, we rank it infrasubspecific, and thus not available (ICZN 2012: Art. 10.2, 45.5, 45.6, glossary). Clausilia costata var. subcostata Bellini, 1908 would also be a primary homonym of Clausilia costata subsp. subcostata Boettger, 1879. Cochlodina costata (Pfeiffer, 1828) does not occur in southern Italy (Welter-Schultes 2012); this taxon was not figured by Bellini (1908a), and thus we are not able to understand what he actually described.Published as part of Fasulo, Giuseppe, Duraccio, Sergio, Federico, Antonio & Crocetta, Fabio, 2019, The (almost) unknown Italian naturalist Raffaello Bellini (1874 - 1930): biography malacological publications, and status of his recent molluscan taxa, pp. 343-369 in Zootaxa 4668 (3) on page 357, DOI: 10.11646/zootaxa.4668.3.3, http://zenodo.org/record/344956
Molecular data reveal cryptic lineages within the northeastern Atlantic and Mediterranean small mussel drills of the <i>Ocinebrina edwardsii</i> complex (Mollusca: Gastropoda: Muricidae)
No full textWe used a molecular phylogenetic approach to investigate species delimitations and diversification in the mussel drills of the Ocinebrina edwardsii complex by means of a combination of nuclear (internal transcribed spacer 2, ITS2) and mitochondrial [cytochrome oxidase subunit I (COI) and 16S] sequences. Our sample included 243 specimens ascribed to seven currently accepted species from 51 sites. Five of the samples were from either the type locality of a nominal species or a close nearby locality (O. edwardsii from Corsica, O. carmelae and O. piantonii from the Kerkennah Islands, O. hispidula from the Gulf of Gabès and O. leukos from the Canary Islands), one from the inferred original locality (O. ingloria from Venice Lagoon), and specimens assigned in the recent literature to O. nicolai. We used a combination of distance- and tree-based species delimitation methods to identify Molecular Operational Taxonomic Units (MOTUs) to compare with the a?priori species identifications. The consensus tree obtained by BEAST on the COI alignment allows the recognition of several distinct clades supported by the three species delimitation methods employed. The eight-MOTUs scenario, shared by the Automatic Barcode Gap Discovery (ABGD) and Generalized Mixed Yule-Coalescent (GMYC) methods, comprises the following major clades: clade A contains the south Tunisian species Ocinebrina piantonii Cecalupo, Buzzurro & Mariani from which the sympatric taxon O. carmelae Cecalupo, Buzzurro & Mariani (new synonym) cannot be separated; clades B and C bring together all populations from the Aegean Sea and some from the Ionian Sea, respectively; clade D groups, on the one hand, the south Tunisian samples morphologically assigned to O. hispidula Pallary and, on the other, Atlantic and Alboran Sea samples (including the Canarian taxon O. leukos Houart); clade E includes a sample from the type locality of O. edwardsii and several samples from the Tyrrhenian Sea; clades F and G correspond to a few samples from the Venice Lagoon and the Tyrrhenian Sea, respectively; clade H groups the bulk of samples from the Adriatic Sea, including samples from the Venice Lagoon morphologically identified as Ocinebrina ingloria (Crosse), and some from the Ionian Sea. No final conclusions could be reached to reconcile the currently recognized morphological taxa with the clades suggested by the COI data. The geographical structure proposed by the mitochondrial markers is similar to that found in other marine invertebrates and partially corresponds to the species defined by shell characters. We propose here a framework for the revision of the Ocinebrina edwardsii species complex, suggesting a geographical pattern for the diversification of this group in the studied area
Revision of the Ocinebrina aciculata species complex (Mollusca: Gastropoda: Muricidae) in the northeastern Atlantic Ocean and Mediterranean Sea
No full textWe used a molecular phylogenetic approach to investigate species delimitation and diversification in the northeastern Atlantic and Mediterranean musseldrills of the Ocinebrina aciculata complex, based on molecular data from topotypical material of many of the nominal taxa. The complex is shown to consist of at least five species: Ocinebrina aciculata (Lamarck, 1822) from the Atlantic and western Mediterranean; O. cf. corallina (Scacchi, 1836) from the central Mediterranean Sea; O. reinai Bonomolo & Crocetta, 2012 from the Tyrrhenian Sea; O. corallinoides Pallary, 1912 from the Gulf of Gabès; and O. aegeensis n. sp. currently known from the Aegean Sea only. The new species is differentiated from the other taxa by very subtle morphological diagnostic features, although it is clearly identified by genetic distance and apomorphic DNA-sequence characters. The identity of Murex corallinus Scacchi, 1836 (type species of Ocinebrina Jousseaume, 1880) could not be defined with certainty, pending genetic comparison of specimens of the "large Tyrrhenian morphotype' (corresponding to the neotype, but not assayed herein) with the assayed "small morphotype'. © The Author 2017
