A New Species

A new species of shrimp-goby was collected at depths of 60–80 m off the southern Israeli Mediterranean coast. A unique ‘DNA barcoding’ signature (mtDNA COI and Cytb) revealed that it differs from any other previously bar-coded goby species clustered phylogenetically with the shrimp-gobies group, in which Cryptocentrus is the most speciose genus. A morphological study supported the assignment of the fish to Cryptocentrus and differentiated the new species from its congeners. The species is described here as Cryptocentrus steinhardti n. sp. However, the present phylogenetic analysis demonstrates a paraphyly of Cryptocentrus and emphasizes the need for revision of the genus based on integrating morphological and genetic characteristics. This finding constitutes the third record of an invasive shrimp goby in the Mediterranean Sea. An intriguing ecological issue arises regarding the possible formation of a fish-shrimp symbiosis in a newly invaded territory. Describing an alien tropical species in the Mediterranean prior to its discovery in native distribution is an unusual event, although not the first such case. Several similar examples are provided in the present article.

A New Species

Benthic monitoring of the marine shallow bottoms off Menorca (Balearic Islands, western Mediterranean) has yielded several specimens of the leptostracan genus Paranebalia Claus, 1880. This finding constitutes the first report of the genus from European latitudes and the Mediterranean Sea and therefore the third leptostracan genus known from the Mediterranean. Specimens are described, illustrated and compared to other known species; they might represent a new species but their state of maturity and the lack of an appropriate diagnosis for the type species of the genus, Paranebalia longipes (Willemöes-Suhm, 1875), did not allow to confirm its taxonomic status.

A New Species

A new species of gobiid, Hazeus ingressus sp. nov. (Teleostei: Gobiidae) is described from the Levantine coast of Turkey. The species probably originates from the Red Sea and represents the 11th alien gobiid species in the Mediterranean Sea. The new species is distinguished from its Indo-Pacific congeners by a combination of the following characters: no dark blotch on the first dorsal fin; caudal fin coloration; scales in lateral series 25-28 (modally 27); second dorsal fin rays I,8; anal fin rays I,8-9; predorsal scales ctenoid 7; short, stout gill rakers 2+8. This finding suggests that the Lessepsian invasion intensely continues with the inclusion of the known species as well as undescribed species.

A new species of Chone (Sabellidae) from the coast of Ustica Island (Mediterranean Sea, north of Sicily) is described. The species, named Chone usticensis sp. nov., is similar to another Mediterranean species, C. filicaudata, in having a long pygidial filiform appendage, but is distinct from this species especially in the peristomium, collar, and in thoracic paleate chaetae shape. A discussion on the presence of the radiolar appendages within the genus Chone is also given.

A New Species

A new amphipod crustacean, Liljeborgia clytaemnestra sp. nov., is described based on specimens from Malta andthe Bay of Naples. It is quite similar to the sympatric L. dellavallei Stebbing, 1906, but it has narrower and moreregular-sized spines on the propodus of pereiopods 3–4. The longest spine on the dorsolateral border of the pedun-cle of uropod 1 is not strongly elongate in adult males, as in L. dellavallei. The apical spines on the lobes of the tel-son are much longer than in L. dellavallei. L. clytaemnestra sp. nov. is actually more similar to two northeasternAtlantic species, the British L. pallida (Spence Bate, 1857) and the Scandinavian L. brevicornis (Bruzelius, 1859)than to the Mediterranean L. dellavallei. In L. clytaemnestra sp. nov., article 2 of the mandibular palp has setae ondistal third, whilst setae are restricted to tip in the two other species. Article 3 of the mandibular palp is also longerin L. clytaemnestra sp. nov. than in the two Atlantic species. The spines of the outer plate of the maxilliped are lon-ger in L. clytaemnestra sp. nov. than in the two other species. The most distal spine of the propodus of pereiopods3–4 is reduced in L. clytaemnestra sp. nov. and L. brevicornis, but not in L. pallida. The serration of the posteriorborder of the basis of pereiopod 7 is much stronger in L. clytaemnestra sp. nov. than in the two other species.Finally, in L. clytaemnestra sp. nov., the spines of the lobes of the telson are longer than in L. pallida. A lectotypeis designated for L. dellavallei. The presence/absence of a posterodorsal tooth on pleonite 3 in L. dellavallei is dis-cussed. The validity of L. kinahani (Spence Bate, 1862) is questioned. An identification key is proposed for Mediterranean Liljeborgia species.

A New Species

Abstract A new species of the thermosbaenacean genus Tethysbaena Wagner,1994 is described as T. ledoyeri n. sp. Together with an as yet undescribed amphipod (Niphargus sp.) it is an inhabitant of the brackish water of an aquifer that flows through the Basse-Provence Urgonian karstic system and reaches the Mediterranean Sea, 15 km east of Marseille, in the “Calanques” coast. The new taxon, being part of the T. argentarii-group, is compared with its closest allies in this group. Preliminary DNA data obtained from two specimens of the new species provide confirmation of its close ties to T. argentarii but also to T. scabra, the two geographically closest described species.

Records of the cumacean genus Iphinoe from Italian coasts are reported with relevant data on the habitat, morphology and geographical distribution of each species. Seven Iphinoe species from the Italian coasts were recorded and are presented here with their own distributional ranges; the description of a new species, Iphinoe daphne n. sp. is also given.                Our results extend the known distribution of some species to new areas of the Mediterranean Sea and suggest that the species Iphinoe adriatica Bâcescu, 1988 can be considered as a nomen dubium, while the presence of I. trispinosa along the Italian coast is doubtful.Finally, a dichotomous key for all Mediterranean Iphinoe species is provided.

A New Species

AbstractMorphological and genetic investigations have led to the identification of Spiophanes adriaticus sp. nov. (Polychaeta: Spionidae) from the North Adriatic Sea (Central Mediterranean). A total of 81 specimens were recorded along the sublittoral zone between 8 and 27.5 m of depth. This species differs from other congeners by having: two pairs of black eyes, a cirriform occipital antenna, dorsal ciliated organs as thin bands usually extending to chaetigers 11–12, dorsal ciliated crests from chaetiger 14–17, undulate glandular opening on chaetigers 5–7, unhooded hooks from the 15th chaetiger and Y shaped tubes. A detailed description and illustrations are provided for the new species. Through DNA barcoding results and comparison of DNA sequences of the new species with those of other congeners available in the GenBank database, the validity of the new finding was confirmed. Spiophanes adriaticus sp. nov. represents the eighth species of Spiophanes recorded for the Mediterranean Sea. A key for the identification of Mediterranean Spiophanes species is also provided.
