The arrival of a second ‘Lessepsian sprinter’? A first record of the red cornetfish Fistularia petimba in the Eastern Mediterranean
Here we document the first occurrence of the red cornetfish Fistularia petimba in the Levantine Basin. This species identity has been confirmed using morphological and molecular tools, and is presented here with simplified illustrations for accurate future identification. This report voices a concern regarding another blitz invasion of a cornetfish into the Mediterranean, following its Lessepsian sprinter congeneric, F. commersonii, one of the most efficacious invaders of the Mediterranean Sea. The wide intra-specific genetic distances found between sympatric F. petimba specimens in the available literature resources may also demonstrate the presence of cryptic diversity within this taxon
Desalination effluents and the establishment of the non-indigenous skeleton shrimp Paracaprella pusilla Mayer, 1890 in the south -eastern Mediterranean
A decade long monitoring programme has revealed a flourishing population of the
non-indigenous skeleton shrimp Paracaprella pusilla in the vicinity of outfalls of
desalination plants off the Mediterranean coast of Israel. The first specimens were
collected in 2010, thus predating all previously published records of this species in
the Mediterranean Sea. A decade-long disturbance regime related to the
construction and operation of the plants may have had a critical role in driving the
population growth.University of Palermo FFR 201

New Mediterranean Biodiversity Records (July 2019)
This is the second collective paper issued in 2019, currently amalgamates new knowledge on the Mediterranean geographic distributions of 17 species from five phyla (six aliens, three cosmopolitans, two east Atlantic records and six natives). The acknowledged species were reported from ten countries, mentioned here from west to east: Spain: first report of the east Atlantic grouper Cephalopholis taeniops in the western Mediterranean and an inclusion of Pontarachna puntulum and Litarachna communis to the pontarachnid fauna of Spain; Morocco: first record of Solea senegalensis from the Moroccan Mediterranean coast; Algeria: a valid confirmation for the presence of Sardinella maderensis; Malta: a first record of the Red Sea stomatopod Erugosquilla massavensis; Italy: a rare observation of the crab Paragalene longicrura from Siciliy and a further integration of the alien brown shrimp Penaeus aztecus to the commercial catch in Sicily; Montenegro: a first record of the Lessepsian bigfin reef squid Sepioteuthis lessoniana from the Adriatic Sea; Turkey: northernmost documentation of the Mediterranean flatworm Prostheceraeus giesbrechtii in the Aegean Sea; Israel: a solid confirmation for the population establishment of both the alien rock shrimp Sicyonia lancifer and two species of angelfish, and a first and deepest record of the crystalline goby Odondebuenia balearica; Lebanon: first record of the jellyfish Pelagia noctiluca; Syria: first records of the crown jellyfish Nausithoe punctate and the smallscale codlet Bregmaceros nectabanus
First record of Epitonium (Parviscala) vaillanti (Jousseaume, 1912) (Mollusca: Gastropoda: Epitoniidae) in the Mediterranean Sea
Epitonium (Parviscala) vaillanti (Jousseaume, 1912), a species previously known only from the Red Sea and Gulf of Aden, is recorded for the first time in the Mediterranean Sea. This new Erythrean alien was found in the course of examination of unidentified specimens from Mediterranean coast of Israel, showed morphological features unknown to any previously recorded Mediterranean epitonid species. To confirm identification, morphological comparison with the syntypic serie of Avalitiscala vaillanti Jousseaume, 1912, stored in the Museum d\u2019Histoire Naturelle de Paris (MNHN) was performed and some remarks of the taxonomy of the species are discussed
The first Indo-West Pacific rock shrimp (Crustacea, Decapoda, Sicyoniidae) in the Mediterranean Sea
Sicyonia lancifer (Olivier, 1811), a widely distributed Indo-West Pacific rock shrimp, was recently collected off the Mediterranean coasts of Turkey and Israel. This is the first record of the species in the Mediterranean Sea. The species is illustrated, and differentiated from its native Mediterranean congener, S. carinata (Brunnich, 1768)

Remarks. Among all the Aoridae known from Mediterranean Sea (Myers 1982; Christodoulou 2013) and Red Sea (Ruffo 1959; Sorbe et al. 2002), only Grandidierella genus has together uropod 3 uniramous and gnathopod 1 carpochelate in male. The only Grandidierella species, recorded in area adjacent to the Mediterranean Sea, are G. japonica from Atlantic coast of France (Jourde et al. 2013) and G. bonnieroides from the Red Sea side of Suez Canal (Schellenberg 1928). These two species can be delimited by the presence/absence of the transverse ridges on the anterior margin of carpus of the gnathopods 1 in male, present in G. japonica and absent in G. bonnieroides. Further, the presence of a submarginal spine on the posterior margin of the carpus of the male gnathopod 1 is a character that distinguishes G. bonnieroides from the other closely related species (Ledoyer 1967; Myers 2009).Published as part of Brutto, Sabrina Lo, Iaciofano, Davide, Lubinevsky, Hadas & Galil, Bella S., 2016, Grandidierella bonnieroides Stephensen, 1948 (Amphipoda, Aoridae) — first record of an established population in the Mediterranean Sea, pp. 518-528 in Zootaxa 4092 (4) on pages 521-525, DOI: 10.11646/zootaxa.4092.4.3, http://zenodo.org/record/26188

Testing foraminiferal environmental quality indices along a well-defined organic matter gradient in the Eastern Mediterranean

The morphological diversity within a species can obscure the correct identification
Critical points of various diagnostic characters and a paucity of information relating to the geographical distribution of several marine species can hinder real species delimitation, particularly if they are supposed to be cosmopolitan. Such constraints characterize many amphipod species and are mainly due to the variation in morphological characters during growth. Specifically, the benthic filter-feeding corophiid Cheiriphotis mediterranea
Myers, 1983 displays different shapes for the male gnathopod 2 as it grows. This variation has hitherto never been described but an extensive sampling has provided us with the opportunity of studying it in detail. More than six thousand individuals, belonging to C. mediterranea, were collected along the Israeli coast during a five-year soft-bottom monitoring survey, comprising 282 sites at a depth between 4 and 37 m. One of the objectives of this study was to integrate the original description of C. mediterranea with the identification of definite six morphotypes, which alternate during growth. A mtDNA Cytochrome c oxidase subunit I sequence was obtained, representing the first molecular datum for the genus Cheiriphotis. The results offer the possibility of including variable morphological characters and molecular sequences in the identification process. Throughout the survey, C. mediterranea was confirmed to be one of the most abundant five species in the study area, in particular in Haifa Bay, where the environmental conditions are stressful. Barely-known abundance and distribution notes relating to this species are reported in this paper; a putative role of bioindicator is also suggested
