“…Among the NIS, we found Gregariella cf. ehrenbergi (Issel, 1869), a species not previously recorded from the Mediterranean Sea (Steger et al 2018). On the ground at the Herzliya Marina, next to the buoy, we found specimens of the non-indigenous intertidal gastropod Cellana rota (Gmelin, 1791).…”

“…ehrenbergi . This species has a complex taxonomic status and cryptic habitat (Steger et al 2018) which may cause significant time lags in first detection (Crooks 2005; Albano et al 2018). Therefore, we cannot determine whether this is truly a recent arrival, but our study demonstrates that the full consideration of all potential vectors can contribute to NIS detection.…”

The potential of large rafting objects to spread Lessepsian invaders: the case of a detached buoy

A diverse and abundant fouling community dominated by Lessepsian non-indigenous species was identified on a 13.5-m-long steel buoy stranded on the Israeli coast but originating from Port Said, at the Mediterranean entrance of the Suez Canal, Egypt. The molluscan community was sampled quantitatively by scraping. Three quarters of the individuals and more than half of the species were non-indigenous. Among the latter, a mytilid bivalve, Gregariella cf. ehrenbergi , was first recorded in the Mediterranean Sea on the basis of these samples, suggesting that the full consideration of all potential vectors can contribute to non-indigenous species detection. Large floating objects in coastal waters, such as buoys, are particularly suitable for colonization by Lessepsian species because hard substrates, and artificial ones in particular, are highly susceptible to the establishment of non-indigenous species. Moreover, their size and persistence enable the development of abundant and mature fouling communities that can disseminate propagules as eggs and larvae over long distances and for extended periods if detached. This report highlights the potential for large rafting debris as a vector of the spread of non-indigenous biota within the Mediterranean Sea.

“…This name has been used for the first Indo-Pacific triphorid species detected in the Mediterranean Sea, likely introduced through the Suez Canal. Notwithstanding the complexity of the group, the introduced species in the Mediterranean Sea probably best matches Viriola bayani Jousseaume, 1884 (Steger et al 2018). Translation of the Latin text.…”

We revise the type specimens of 132 nominal species of worldwide Triphoridae stored in the Natural History Museum of the United Kingdom (NHMUK), London. We provide the species name in its original combination, followed by bibliographic details of the original description, the location of the known type material, the original description (and its translation when in Latin), a diagnosis and curatorial or nomenclatural notes. We illustrated most specimens in the type series in colour and with SEM imaging and we have added the original figure whenever possible. The specimens of Triphorisalveolatus, T.granulatus, T.suturalis and T.verrucosus, all A. Adams & Reeve, 1850, T.pfeifferi Crosse & Fischer, 1865 and T.cucullatus de Folin, 1867, previously considered type material, are not considered here belonging to the type series. Adams & Reeve’s taxa should be considered nomina dubia. The name Triphorainsularum is a manuscript name by H.E.J. Biggs who deposited “types” in the NHMUK but refrained from introducing the name due to the lack of apex of the studied material. We selected lectotypes for six species (T.concors Hinds, 1843, T.maxillaris Hinds, 1843, T.fuscomaculata E.A. Smith, 1904, T.shepstonensis E.A. Smith, 1906, T.eupunctata G.B. Sowerby III, 1907, and T.rufula Watson, 1886) to stabilize the nomenclature. Finally, we illustrate original specimens (although not types) of three species described by Turton, whose type material is lost.

“…Although some work on native assemblages is available, research has been polarized on the burgeoning number of non-indigenous species, here mostly of Red Sea origin (e.g. Mienis 2010;Albayrak 2011;Crocetta et al 2017;Steger et al 2018). Importantly, no work has been conducted on mesophotic molluscs.…”

Low diversity or poorly explored? Mesophotic molluscs highlight undersampling in the Eastern Mediterranean

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 mesophotic habitats are virtually unknown. We here describe two mesophotic (77–92 m depth) molluscan assemblages at a rocky reef and on a soft substrate off northern Israel. We record 172 species, of which 43 (25%) are first records for Israel and increase its overall marine molluscan diversity by 7%. Only five of these species have been reported in recent surveys of the nearby Lebanon, suggesting that our results are robust at a broader scale than our study area and that the reported west-to-east declining diversity gradient in the Mediterranean needs a reappraisal based on proper sampling of the eastern basin. We found only four (2%) non-indigenous species, represented by seven (0.5%) specimens. These results suggest that pristine native assemblages still thrive at this depth in Israel, in contrast to the shallow subtidal heavily affected by global warming and biological invasions, calling for strong conservation actions for these valuable but vulnerable habitats.
