A representative of the genus Hemiasterella Carter, 1879 was found for the first time in the Mediterranean Sea during sampling in the shallow waters of the northern Aegean Sea. The new species, H. aristoteliana, is compared with Atlantic Hemiasterella elongata Topsent, 1928. The status of the family Hemiasterellidae is discussed.

AbstractAllopodocotyle tunisiensis sp. nov. is described from the intestine of Solea aegyptiaca Chabanaud collected from the Gulf of Gabès in the Mediterranean Sea off Tunisia. The new species belongs to the group C of Allopodocotyle Pritchard, 1966 species (sensu Bray 1987). It differs from its congeners in this group by the shape of the seminal vesicle and the anterior extend of the vitellarium which varies between just posterior to the ventral sucker and anterior margin. A key to the Allopodocotyle species of group C is presented. The status of the genera Allopodocotyle and Macvicaria (Gibson and Bray 1982) are briefly discussed.

The presence of the crab Actaeodes tomentosus, native to the Indo-Pacific Ocean and the Red Sea, is documented for the first time in the Mediterranean Sea, on the basis of two specimens collected from Rhodes Island (Aegean Sea), a marine area particularly vulnerable to warm-water alien invasions. Along with the recent report of Xanthias lamarckii in similar conditions and region, the finding of another non-indigenous xanthid opens many questions regarding their occurrence in the area. Apart from the Lessepsian migration, other possible vectors of introduction are therefore examined.

A systematic account is given of 17 families, 25 genera, and 32 species of anthoathecate hydroids and limnopolyps reported from Hawaii. Applying Reversal of Precedence provisions in zoological nomenclature, the familiar hydrozoan genus names Hydractinia Van Beneden, 1844a, Bimeria Wright, 1859a, and Porpita Lamarck, 1801 are designated as valid and as nomena protecta, while seldom-used older names threatening them (the synonyms Echinochorium Hassall, 1841 and Manicella Allman, 1859a, and the homonym Porpita Soldani, 1789 respectively) are relegated to nomena oblita. Also designated a nomen oblitum is the name Pyxidium Leuckart, 1856, threatening its junior but widely used synonym Ectopleura L. Agassiz, 1862. The species name Bimeria vestita Wright, 1859a is rendered valid and a nomen protectum, while its virtually unused senior synonym Manicella fusca Allman, 1859 becomes a nomen oblitum. Hydrodendrium Nutting, 1905 is reinstated as a valid genus, distinct from Hydractinia and replacing its junior objective synonym Nuttingia Stechow, 1909. The spelling of Hydrodendridae Nutting, 1905 is emended to Hydrodendriidae, but that family name is retained as a synonym of Hydractiniidae. Usage of the familiar generic name Sphaerocoryne Pictet, 1893 is upheld by recognizing it and its former senior subjective synonym Corynetes Haeckel, 1879 as valid. The correct spelling of the family name originally founded as Olindiadae Haeckel, 1879 is taken to be Olindiidae, and spelling of the species name Solanderia misakinensis (Inaba, 1892), first established as Dendrocryne (sic) misakii, is stabilized. One new species, Stylactaria munita, is described from shallow waters at Hawaii Kai, Oahu. Lectotypes are designated for Corydendrium corrugatum Nutting, 1905 and Corydendrium minor Nutting, 1905 (=Turritopsis minor), both originally described from Hawaii. Type material of Balea mirabilis Nutting, 1905 (=Balella mirabilis), originally described from waters between the islands of Molokai and Maui, could not be located. Six anthoathecate species [Corydendrium parasiticum (Linnaeus, 1767), Bimeria vestita, Amphinema sp., Eudendrium carneum Clarke, 1882, Ectopleura viridis (Pictet, 1893), and Sphaerocoryne bedoti Pictet, 1893] are recorded from Hawaii for the first time.

AbstractDuring benthic surveys in the northern Aegean Sea, 188 amphipod species were found; 39 among these comprise new records for the amphipod fauna of the eastern Mediterranean Sea, 41 are reported for the first time from the Aegean Sea and 62 are new for the fauna of the northern Aegean Sea. A checklist of the amphipods known from the Aegean Sea up to the present is given (239 species), along with their distribution in certain Mediterranean areas. For the most interesting species found, information on their distribution and their habitat is given. The amphipod fauna of the above areas is estimated, on the basis of the relevant literature. Finally, the affinities among these areas using the coefficient of Czekanowski, along with the number of species common to each pair of areas, are estimated.

First Time

Three sampling surveys were carried out, by SCUBA diving, in the Algarve (southern Portugal) in December 2007. A total of 57 species of gymnolaemate Bryozoa were identified. Of these, eight species were new to science (Mollia cristinae sp. nov., Hippoporina teresae sp. nov., Schizoporella spinosa sp. nov., Fenestrulina inesae sp. nov., Celleporina derungsi sp. nov., Dentiporella saldanhai sp. nov., Rhynchozoon celestinoi sp. nov. and Rhynchozoon rosae sp. nov.). Another 16 species are cited for the first time in Portuguese waters; of these, Stephanollona contracta is cited for the first time in European continental waters. Reference material deposited in several collections was also revised, and lectotypes and paralectotypes were selected for Mollia multijuncta and Dentiporella sardonica, species subjected to diverse interpretations. In addition Rhynchozoon revelatus was found to be a junior synonym of D. sardonica. The species collected in the study area reflect the existence of Lusitanian, Mauretanian and Mediterranean influences; the latter influence is of interest as the Mediterranean species found were previously considered endemic to the Mediterranean Sea and are usually found in shallow waters. Finally, a large degree of intracolonial variability was observed in some of the species studied, especially in Stephanollona armata, which may be taken into account in studies of the geographical variability and differentiation of cryptic species.

A New Species

A new species, Topsentia vaceleti n. sp., was collected from 70m depth, on a coralligenous bed of the Aegean Sea by trawl(sponge fishing gear “gagava”). The specimen is spherical, 8 cm in diameter, with deep surface grooves. It has a totallydisordered choanosome and a tangential ectosomal skeleton, typical of Topsentia, but exhibits a different type of spicula-tion. This species differs from the other members of the genus by possessing both principal oxeas and secondary oxeas,the latter much longer but thinner, bent and in some cases flexuous or twisted. This is the fourth species of Topsentia Berg, 1899 reported from the Mediterranean Sea.

A single specimen of Xanthias lamarckii was collected on March 2013 from the shallow waters of Chtenia, a rocky islet near Rhodes Island, south-eastern Aegean Sea. The occurrence of this Indo-West Pacific species is reported for the first time in the Mediterranean waters and documents the ongoing process of biological invasion of the basin. The vector of introduction of X. lamarckii is unknown so far, waiting for future information on establishment and spread of the species in its new environment.

Few of the ca 50 species of Columbellidae found in the eastern Atlantic Ocean have planktotrophic larval development denoted by a multispiral protoconch. One species of the genus Mitrella, ranging from the mid-Atlantic seamounts to the Alboran Sea, is here described as new to science and the geographic and bathymetric distributions of another three species, Amphissa acutecostata (Philippi, 1844), Mitrella canariensis (d'Orbigny, 1840) and M. nitidulina (Locard, 1897) are updated. The name Mitrella canariensis is shown to have precedence over M. pallaryi (Dautzenberg, 1927). Mitrella nitidulina is absent in the Mediterranean Sea, and A. acutecostata, the only amphiatlantic species, is recorded for the first time as living in the Alboran Sea. There is a definite differentiation in the bathymetrical range of these species, with M. canariensis being the shallowest and M. nitidulina being the deepest.
