The calcareous crusted epiphytic algae are a group of extremely delicate, fragile and poorly studied algae. The subfamily Melobesioideae (Corallinophycidae, Rhodophyta) includes the genus Melobesia, which has no record of molecular analysis.However, thanks to measurement data, it was possible to find enough similarity for taxonomic identification of two species: Melobesia rosanoffii (Foslie) Lemoine, described for the first time in South Atlantic Ocean, and Melobesia membranacea (Esper) Lamouroux, first described in southern Brazil. The group has undergone several changes of classification from animals to plants. Today crusty coralline algae have great importance due to the possibility of easy spore dispersal between oceans.

Bathygnathia magnifica sp.n., a new bathyal species of Gnathiidea (Crustacea, Isopoda), is described for science. It was collected from off southern Brazil, at 387 m depth. The present find seems of interest, not only because for the first time a species of Bathygnathia is reported at such a depth, but because it is the first species of the genus bearing eyes, in spite of depauperate.

Two larval Symphysanodon, collected off the coast of Rio de Janeiro, southern Brazil (at 22º32’50.0” S, 040º04’09.0” W), beyond the 1,000 m isobath, are the first specimens of the monotypic family Symphysanodontidae to be reported from the western South Atlantic Ocean. We are unable to assign the larvae to a described species and entertain the idea that the Brazilian material may represent an undescribed species.

Dispersal Events

AbstractAlbatrosses and other seabirds are generally highly philopatric, returning to natal colonies when they achieve breeding age. This is not universal, however, and cases of extraordinary vagrancy are rare. The Tristan Albatross (Diomedea dabbenena) breeds on Gough Island in the South Atlantic Ocean, with a small population on Inaccessible Island, Tristan da Cunha, ca 380 km away. In 2015, we observed an adult male albatross in Gonydale, Gough Island, which had been ringed on Ile de la Possession, Crozet Islands in 2009 when it was assumed to be an immature Wandering Albatross (D. exulans). We sequenced 1109 bp of the cytochrome b mitochondrial gene from this bird, and confirmed it to be a Tristan Albatross, meaning its presence on Crozet 6 years previous, and nearly 5000 km away, was a case of prospecting behaviour in a heterospecific colony. Given the challenges in identifying immature Diomedea albatrosses, such dispersal events may be more common than thought previously.
