Polychaete worms are known to thrive in extreme environmental conditions, however little is known about how polychaete species will respond to major climatic stressors, such as ocean acidification. Here, we examined the distribution of Fabriciidae (Annelida, Sabellida) species along a gradient of ocean acidification, caused by carbon dioxide (CO2) vent emissions in a shallow, coastal system off the island of Ischia (Tyrrhenian Sea, Italy). A total of 265 specimens of Fabriciidae, representing six species from five genera, were collected along the gradient. Most of the species were found across the entire CO2 gradient, suggesting polychaetes may have a high tolerance for ocean acidification in the future. Two of the species were new to science, and two of the genera were previously unrecorded in the Mediterranean. A full description of the new species Brifacia aragonensis sp. nov. and Parafabricia mazzellae sp. nov. is given, both of which were most abundant in the most acidified areas (pH 6.6–7.2). The geographical distribution and ecology of the new taxa, as well as of the other fabriciid species collected, is discussed. Taxonomic keys to identify the Fabriciidae species currently recorded in the Mediterranean Sea are also provided.

The species Microdeutopus sporadhi (Crustacea: Amphipoda: Aoridae), endemic of the Mediterranean Sea, was described by Myers in 1969 on material collected from the Aegean Sea in a sheltered environment with high sedimentation rates. A check on the distribution and ecology of M. sporadhi showed that: — although not mentioned in the checklist of amphipods of the Italian seas, it was already found in the central Tyrrhenian Sea in 1983-84 and in the northern Adriatic Sea in 2002-03; — it was rarely found in the Mediterranean Sea, one of the most studied basins as concerns amphipod fauna; but notwithstanding the few records available, the wide ecological spectrum of this species was pointed out. The present study, conducted off the Island of Ischia (Gulf of Naples, Italy), showed the presence of rich and well established populations through time, but only in a peculiar substratum (artificial collectors) and environment (low pH values). The species seems to be able to withstand harsh environmental conditions and probably to conceal itself through a cryptic behaviour, escaping traditional sampling methods. The role of rare or hidden species in bio-assessment should be re-evaluated.

Two new species of oribatid mites of the genus Neoribates (Oribatida, Parakalummidae) are described based on adult specimens from leaf litter in the Montagne d'Ambre National Park of North Madagascar. Neoribates africanus sp. nov. and N. madagascarensis sp. nov. clearly differs from all species of the genus by the absence of interlamellar seta (including alveolus). An identification key and data on distribution and ecology of known African species of Parakalummidae are presented.

The present study, based on a faunistic and ecological survey of caridean shrimps from Dong’ao Island, Guangdong Province, expands the knowledge of morphology, colouration, and distribution of three species, two of which belong to genus Caridina and one belong to genus Marcrobrachium. Caridina zhujiangensis, new species is distinguished from the closely related species C. typus H. Miline Edwars,1837 by shorter rostrum and with only one ventral margin teeth, the shape of the endopod of the first male pleopod and the appendix interna arising from distal 1/3 of endopod. Macrobrachium dongaoensis, new species, can be distinguished from its congeners M. inflatum Liang & Yan, 1985 by a combination of characters which includes short rostrum, the subequal male second pereiopods, the non–inflated palm, and the longer merus. A diagnosis of three speciesmore and full description of two new species are presented.

AbstractTwo new nematode species of the genus Mesacanthion, M. obscurum sp. n. and M. propinquum sp. n., both isolated from sediment in the Mediterranean Sea off the coast of Israel, are described and illustrated. Mesacanthion obscurum sp. n. is similar to M. diplechma and M. southerni, but differs from the first species by having a narrower labial region, shorter outer labial setae, shorter right spiculum, and shorter distance from supplement to cloacal aperture; and from the second species by a shorter female body, shorter outer labial setae, shorter distance from supplement to cloacal aperture, and the presence of a ventral protuberance on the male tail. Mesacanthion propinquum sp. n. resembles M. southerni and M. obscurum sp. n., but differs from the first species by having a shorter female body, less slender tail, narrower labial region, shorter outer labial setae, shorter distance from supplement to cloacal aperture, and absence of transverse striations on the right spicule; and from M. obscurum sp. n. by the shorter outer labial setae (10-15 vs 37-44 μm), shorter distance from supplement to cloacal aperture (28-31 vs 36-59 μm) and absence of transverse striations on the surface of the right spicule. A key is provided for those Mesacanthion species possessing anisomorphic and anisometric spicules.
