This study provides the first report of the presence of Coolia malayensis in the Mediterranean Sea, co-occurring with C. monotis. Isolated strains from the Gulf of Gabès, Tunisia (South-eastern Mediterranean) were identified by morphological characterization and phylogenetic analysis. Examination by light and scanning electron microscopy revealed no significant morphological differences between the Tunisian isolates and other geographically distant strains of C. monotis and C. malayensis. Phylogenetic trees based on ITS1-5.8S-ITS2 and D1‒D3/28S rDNA sequences showed that C. monotis strains clustered with others from the Mediterranean and Atlantic whereas the C. malayensis isolate branched with isolates from the Pacific and the Atlantic, therefore revealing no geographical trend among C. monotis and C. malayensis populations. Ultrastructural analyses by transmission electron microscopy revealed the presence of numerous vesicles containing spirally coiled fibers in both C. malayensis and C. monotis cells, which we speculate to be involved in mucus production.

AbstractIn this study we report the first finding of the red alga Acanthosiphonia echinata in the Mediterranean Sea. Specimens were identified using the DNA barcoding method and, in particular, the plastidial rbcL and the mitochondrial COI-5P markers. This species has been considered to be restricted to the western Atlantic and was reported in blooms from North Carolina to South Carolina. In 2015 the introduction of this species in Southeast Asia (Indonesia) was reported. Probably this taxon was introduced in the Mediterranean Sea from Indonesian populations associated with seaweed farming activities or hull fouling, via the western Atlantic-Mediterranean-Indonesia ship route.

We report the first record in the Mediterranean Sea of the minute Indo-Pacific venerid bivalveCostellipitar chordatum. The species has recently established a small population off the central coast of Israel. Numerous live specimens ofGouldiopa consternans, at several locations off the Israeli coast, confirm the presence of a fast growing population. This is the first record of the species from Israel, following a recent report from Turkey.

First Time

The ribbon worm Evelineus mcintoshii is reported for the first time from the Mediterranean Sea. Observations that took place, during two algal surveys, on the intertidal abrasion platforms at the middle of the Levantine Sea of Israel indicated that this species is hiding inside a mixture of local and non-indigenous marine seaweeds. It is probably another alien species, one of many, that adopted the Levantine basin of the Eastern Mediterranean due to tropical environmental conditions that characterize this sea. We discuss the first record of this species and its possible origins as well as the first report of Notospermus geniculatus, the other marine nemertean species recently reported from Israel.

Submarine Cave

During a survey of the Italian marine meiofauna, several specimens of the rare gastrotrich genus Xenodasys were found in a submarine cave along the Ionian coast of Apulia. The finding represents the first record of the genus for the Mediterranean Sea and reinforces the consideration of marine caves as habitats of high naturalistic value. The specimens, analysed using different microscopy techniques, showed a new species, named Xenodasys eknomios. Scanning electron microscopy, unveiling the astonishing morphology of this unusual gastrotrich, indicates that, due to technical artefacts, light microscopy may generate unreal features, which in the past may have led to the misinterpretation of the anatomical traits of these creatures. Transmission electron microscopy indicated that the ‘Seitenfüsschen’, are genuine elements of the adhesive apparatus, in contrast with previous investigation, which attributed an exclusive sensorial function to these organs. Confocal laser scanning microscopy, combined with actin-binding fluorochromes, revealed muscular elements in a region where originally the muscular chordoid organ was reported for gastrotrich species belonging to the genus Chordodasys. A taxonomic revision of the species currently allocated to the genus Xenodasys led to the establishment of Chordodasiopsis gen. nov. to integrate the former Xenodasys (=Chordodasys) antennatus and to the drafting of emended diagnosis of the genus Xenodasys. An overview of the high-rank systematization of these genera is also provided, with the establishment of Xenodasyidae fam. nov. to allocate both Xenodasys and Chordodasiopsis.

Pomadasys incisus is a thermophilous coastal subtropical fish species belonging to the family Haemulidae. Originally described from Gambia, this species is widely distributed in the Eastern Atlantic from Galicia to South Africa. It has also been recorded in the Mediterranean Sea since 1840, presumably expanding its distribution in the next decades, although the species could have been already present in the basin, but simply overlooked until the mid XIX century. In this study, we first record P. incisus from Cyprus (eastern Mediterranean Sea), based on two opportunistic observations obtained through a citizen-science project and review the distribution of this species in the Mediterranean Sea. The present sighting raises the question on whether this species is a late arrival in the country or its presence has just been neglected until now. Based on present data, the most likely hypothesis is the latter one, with P. incisus occurring in low densities and being overlooked due to the absence of field studies. Whatever is true, some intrinsic or extrinsic factors may have played a role in limiting its spread or wide establishment in the above-mentioned country.

Two specimens of the alien cardinal fish Apogon fasciatus (White, 1790) are recorded for the first time from Turkey and second time from the Mediterranean Sea. This is the fourth Indo-Pacific apogonid species documented in the Mediterranean Sea, and the introduction of this species to the eastern Mediterranean is due to migration from the Red Sea via the Suez Canal.

AbstractIn 2014, Berghia marinae Carmona, Pola, Gosliner & Cervera, 2014 from Senegal was described along with the revision of the genus Berghia Trinchese, 1877. In this study, we establish a second record for the senegalese species B. marinae in the Mediterranean Sea, 4,000 Km away from its type location. The morphological mismatch from the original description hampered its identification, and thus, a molecular approach was needed. Multilocus phylogenetic trees were inferred from Maximum-likelihood and Bayesian analyses based on partial DNA sequences of the mitochondrial cytochrome c oxidase subunit I and 16S rRNA genes, and the nuclear gene histone-3. Species delimitation analyses were performed to support the phylogenetic results and a new morphological description is provided complementing earlier information on this barely known species.

AbstractCymothoa indica, a typical Indo-Pacific genus and species, is reported for the first time in the eastern Mediterranean Sea. Specimens were found parasitizing mainly barracudas (Sphyraenidae) from Lebanon. Female and male specimens are described on collected materials. To date, the genus Cymothoa has not been reported in the Mediterranean Sea although it is widely represented in other areas of the world. It is suggested that C. indica should be added to the list of exotic species introduced from the Red Sea and known as Lessepsian migrants.
