The Collective Article 'New Mediterranean Biodiversity Records' of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of native and alien species respectively. The new records of native fish species include: the slender sunfish Ranzania laevis and the scalloped ribbonfish Zu cristatus in Calabria; the Azores rockling Gaidropsarus granti in Calabria and Sicily; the agujon needlefish Tylosurus acus imperialis in the Northern Aegean; and the amphibious behaviour of Gouania willdenowi in Southern Turkey. As regards molluscs, the interesting findings include Ischnochiton usticensis in Calabria and Thordisa filix in the bay of Piran (Slovenia). The stomatopod Parasquilla ferussaci was collected from Lesvos island (Greece); the isopod Anilocra frontalis was observed parasitizing the alien Pteragogus trispilus in the Rhodes area. The asteroid Tethyaster subinermis and the butterfly ray Gymnura altavela were reported from several localities in the Greek Ionian and Aegean Seas. The new records of alien species include: the antenna codlet Bregmaceros atlanticus in Saronikos Gulf; three new fish records and two decapods from Egypt; the establishment of the two spot cardinal fish Cheilodipterus novemstriatus and the first record of the marble shrimp Saron marmoratus in semi-dark caves along the Lebanese coastline; the finding of Lagocephalus sceleratus, Sargocentron rubrum, Fistularia commersonii and Stephanolepis diaspros around Lipsi island (Aegean Sea, Greece); the decapod Penaeus hathor in Aegean waters; the decapod Penaeus aztecus and the nudibranch Melibe viridis in the Dodecanese islands; the finding of Pinctada imbricata radiata in the Mar Grande of Taranto (Ionian Sea, Italy) and the Maliakos Gulf (Greece).

According to reports, the following 16 species have extended their distribution to other Mediterranean areas or have made a new appearance in other regions. The first category includes the following organisms: The rare and common Indo-Pacific seaweed Codium arabicum (Lebanese coasts), the acari Thalassarachna affinis (Marmara Sea), and the non-indigenous nudibranch Flabellina rubrolineata, which has been found in several areas of the Aegean Sea. In addition, the rare sea slug Thecacera pennigera (Mar Piccolo of Taranto), the fangtooth moray Enchelycore anatina (National Marine Park of Zakynthos, Ionian Sea), the carangid Seriola fasciata (Gulf of Antalya), Lagocephalus sceleratus (SE Ionian Sea), the reticulated leatherjacket Stephanolepis diaspros (Slovenia, N. Adriatic Sea), the marbled stingray, Dasyatis marmorata (NE Levantine), the starry smooth-hound Mustelus asterias (Iskenderun Bay, NE Mediterranean), the cephalopod Ommastrephes bartramii (Ionian Sea) have also been reported. The Atlantic crab Dyspanopeus sayi has expanded to many Italian areas and the blue crab Callinectes sapidus to a lake in N. Greece and in the S. Adriatic Sea. Finally, Farfantepenaeus aztecus has been found in the Ionian Sea, thus showing its wide expansion in the Mediterranean. The larval stages of Faccionella oxyrhyncha have been found, after many years, in the Aegean Sea and the first report of an existence on intersexual acari Litarachna duboscqi in Split (Adriatic Sea) was reported.

The Collective Article "New Mediterranean Biodiversity Records" of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article has adopted a country-based classification and the countries are listed according to their geographic position, from west to east. New biodiversity data are reported for 7 different countries, although one species reported from Malta is new for the entire Mediterranean basin, and is presumably also present in Israel and Lebanon (see below, under Malta). Italy: the rare native fish Gobius kolombatovici is first reported from the Ionian Sea, whilst the alien jellyfish Rhopilema nomadica and the alien fish Oplegnathus fasciatus are first reported from the entire country. The presence of O. fasciatus from Trieste is concomitantly the first for the entire Adriatic Sea. Finally, the alien bivalve Arcuatula senhousia is reported for the first time from Campania (Tyrrhenian Sea). Tunisia: a bloom of the alien crab Portunus segnis is first reported from the Gulf of Gabes, where it was considered as casual. Malta: the alien flatworm Maritigrella fuscopunctata is recorded in the Mediterranean Sea for the first time, on the basis of 25 specimens. At the same time, web searches include possible unpublished records from Israel and Lebanon. The alien crab P. segnis, already mentioned above, is first formally reported from Malta based on specimens collected in 1972. Concomitantly, the presence of Callinectes sapidus in Maltese waters is excluded since based on misidentifications. Greece: the Atlantic northern brown shrimp Penaeus atzecus, previously known from the Ionian Sea from sporadic records only, is now well established in Greek and international Ionian waters. The alien sea urchin Diadema setosum is reported for the second time from Greece, and its first record from the country is backdated to 2010 in Rhodes Island. The alien lionfish Pterois miles is first reported from Greece and concomitantly from the entire Aegean Sea. Turkey: the alien rhodophyte Antithamnion hubbsii is first reported from Turkey and the entire eastern Mediterranean. New distribution data are also provided for the native fishes Alectis alexandrina and Heptranchias perlo. In particular, the former record consists of a juvenile measuring 21.38 mm total length, whilst the latter by a mature male. Cyprus: the rare native cephalopod Macrotritopus defilippi, and the alien crab Atergatis roseus, sea slug Plocamopherus ocellatus and fish Cheilodipterus novemstriatus are first recorded from the entire country. Lebanon: the alien crabs Actaea savignii and Matuta victor, as well as the alien fish Synanceia verrucosa, are first recorded from the entire country. In addition, the first Mediterranean record of A. savignii is backdated to 2006, whilst the high number of M. victor specimens observed in Lebanon suggest its establishment in the Basin. The Atlantic fishes Paranthias furcifer and Seriola fasciata, and the circumtropical Rachycentron canadum, are also first reported from the country. The P. furcifer record backdates its presence in the Mediterranean to 2007, whilst S. fasciata records backdate its presence in the eastern Mediterranean to 2005. Finally, two of these latter species have been recently ascribed to alien species, but all three species may fit the cryptogenic category, if not a new one, better.

Microlipophrys adriaticus (Steindachner & Kolombatovic, 1883) is an endemic blenny of the Mediterranean Sea. It is also known from the Sea of Marmara and the Black Sea. However, unlike other species of combtooth blennies, M. adriaticus is a fish with a limited distribution in Adriatic Sea, especially in the north, where it can be common. We report here the first record of this species from the waters of the Ionian Sea. © 2015 Check List and Authors.

Background. In the Mediterranean Sea, habitat preferences of small benthic fishes of shallow waters have been poorly investigated. Although combtooth blennies are not of interest for fisheries, they are often the dominant fish community on rocky bottoms within the first meter of depth and in tidal pool environments, playing so an important role in the functioning of the coastal ecosystem. This study represents the first detailed investigation concerning habitat preference and depth distribution of combtooth blennies in the Ionian Sea. Materials and methods. Occurrence and abundance of species were investigated by a non-destructive visual census method using snorkelling or SCUBA diving. We investigated 5 habitat types (bathymetric intervals between 0 and 3 m of depth) to find difference in species richness and abundance in each one and between. Studies were conducted from June to October 2014 in the south-eastern coast of Sicily. Statistical method of the electivity index (EI) and principal component analysis (PCA) were utilized for the evaluation of the habitat preference of 11 species of combtooth blennies. Depth distribution for each species was box-plotted. For each habitat and depth, the Shannon-Wiener Index (H’) and the Simpson Index (D) were calculated. Diversity profiles were performed in order to give a better understanding of the correlation between diversity and both habitat types and depth. Results. During a total of 2485 observations of combtooth blennies a total of 11 species were recorded: Aidablennius sphynx (Valenciennes, 1836); Coryphoblennius galerita (Linnaeus, 1758); Lipophrys trigloides (Valenciennes, 1836); Microlipophrys canevae (Vinciguerra, 1880); Parablennius gattorugine (Linnaeus, 1758); Parablennius incognitus (Bath, 1968); Parablennius pilicornis (Cuvier, 1829); Parablennius sanguinolentus (Pallas, 1814); Parablennius zvonimiri (Kolombatović, 1892); Salaria pavo (Risso, 1810); Scartella cristata (Linnaeus, 1758). The maximum Shannon-Wiener Index (H’= 2.335) and Simpson Index (D = 0.898) values were recorded on “rocks with algal cover”; while, concerning the depth, the maximum values of both indices were recorded within the first meter. The diversity indices showed the highest values in the most heterogeneous habitat types. There was a negative correlation between depth and diversity indices. Results showed a clear habitat preference for the following species: A. sphynx, P. gattorugine, P. sanguinolentus, S. pavo and S. cristata. Conclusion. This study highlights the importance of depth and habitat heterogeneity in biological diversity, species richness and population abundances of combtooth blennies in the Mediterranean Sea. © 2016, Scientific Society of Szczecin.

Background. Seahorses are considered vulnerable and endangered fish species in many parts of the world. We found a conspicuous and stable population of Hippocampus guttulatus Cuvier, 1829 in the Mar Piccolo of Taranto (Ionian Sea), known of its substantial pollution and fluctuations in environmental parameters. The aims of our study were to demonstrate the role of habitat protection in the conservation of this species, the adaptability of the long-snouted seahorse to the water pollution and variable physico-chemical parameters, as well as the habitat preferences of H. guttulatus under particular conditions of this coastal lagoon. Materials and methods. The areas of diving were randomly selected within both parts of the Mar Piccolo of Taranto. Observations were based on snorkelling and scuba diving at different depths from 0 through 4 m. For each dive, in each inlet, all types of environment were explored, divided in four categories based on the nature of the substrate. From the summer of 2011 to the summer of 2013, a total of 23 days of observations were carried, for a total period of 69 h. Results. A total number of 196 sightings of Hippocampus guttulatus were recorded. The data show a clear preference of the fish studied for the artificial hard substrates, piers and wharves in particular. Only 3 specimens were observed on algal meadows. The western part of the lagoon harbours the largest number of the specimens. Concerning both depth and the three years period, no significant differences were found in the abundance. Conclusion. This study highlights the ecological importance of the coastal lagoon of the Mar Piccolo of Taranto. We report quantitative data about this population of seahorses with considerations and discussions about the presence and distribution of the specimens, their preferred substrates, and the peculiar polluted environment that they inhabit. Future studies are necessary to better understand the role of habitat protection for seahorses and to improve protection measures for the management and conservation of the species.

Hypleurochilus bananensis is one of the rarest species of Blenniidae in the Mediterranean Sea. Only few records have been made in the whole Basin. Due to its rarity, H. bananensis is poorly studied and little is known about its biology. In this study, we provide additional data on this rare species. In particular, we describe its habitat, sexual dimorphism, presence and distribution with several new records in both Tyrrhenian and Ionian Sea. Studies were conducted in the period from 2011 to 2014. Observations were carried out both by snorkelling and SCUBA diving. In the natural environment, we observed the behavior and coloration in both sexes. For two mature sampled specimens of both sexes, we examined the morphology, providing the first detailed information about the differences between them. Sexual dimorphism is very pronounced and past descriptions of this species were based only on female specimens. This could lead to misidentification cases. Indeed, especially the morphology and chromatic pattern of the male are similar to those of other combtooth blennies species. Furthermore, we report data about reproduction, habitat preference and consideration about its presence in Italian seas. © 2016, Institute of Oceanography and Fisheries. All rights reserved.
