A New Species

AbstractThe present study describes a new species, Ligophorus uruguayense, parasitizing the gills of Mugil platanus Günther, 1880 from the coast of Uruguay. It differs from all other species of the genus mainly in the shape of the ventral bar, the thick process at the distal end of the inner root of ventral anchors, the J-shaped penis accessory piece and the vaginal tube showing transverse annulations at its distal end, the host species, and geographical distribution. This is the first description of a species of Ligophorus from a mullet in the South Atlantic Ocean.

A new species of the genus Acantholaimus is described from the South Atlantic, in the Potiguar Basin off the continental shelf of northeast Brazil. Acantholaimus marliae sp. n. is characterized by the long body; numerous somatic setae arranged in four sublateral longitudinal rows; buccal cavity with five solid teeth (four subventral and one dorsal), with the largest tooth dorsally located and the most protuberant between the subventral teeth shaped similarly to a "bottle opener"; and spiral fovea amphidialis. Acantholaimus marliae sp. n. is the only species described for the genus that has a spiral fovea amphidialis. This is the fifth species of Acantholaimus described from shallow water. An emended diagnosis of the genus is provided.

A New Species

A new species of bone-eating annelid, Osedaxbraziliensissp. n., found in a sunken whale carcass at a depth of 4,204 m at the base of the São Paulo Ridge in the South Atlantic Ocean off the Brazilian coast is described. The organism was retrieved using the human-occupied vehicle Shinkai 6500 during the QUELLE 2013 expedition. This is the 26th species of the genus and the first discovery from the South Atlantic Ocean, representing the deepest record of Osedax worldwide to date. This species morphologically resembles Osedaxfrankpressi but is distinguished by the presence of a yellow bump or patch behind the prostomium and its trunk length. Molecular phylogenetic analysis using three genetic markers (COI, 16S, and 18S) showed that O.braziliensissp. n. is distinct from all other Osedax worms reported and is a sister species of O.frankpressi.

A new species of Goneplax Leach, 1814 (Crustacea, Decapoda, Brachyura, Goneplacidae) from the south Atlantic and the western limits of the Indo-West Pacific region, long confused with G. rhomboides (Linnaeus, 1758)

A new species of Goneplax Leach, 1814, G. clevai n. sp., is described from the South Atlantic and the western limits of the Indo-West Pacific region. The new species was for a long time confused with G. rhomboides (Linnaeus, 1758), senior synonym of Cancer angulata Pennant, 1777, Ocypoda bispinosa Lamarck, 1801, Ocipode [sic] longimana Latreille, 1803, Goneplax rhomboїdalis Risso, 1827, and Gelasimus bellii Couch, 1838. Goneplax rhomboides is found in the northeastern Atlantic and the Mediterranean Sea. Museum collections contain mixed material belonging to the two species. Carcinoplax barnardi Capart, 1951, which is close to Goneplax, is also present in the South Atlantic, its distribution overlapping that of the new species. The sympatry of G. rhomboides and G. clevai n. sp. is uncertain owing to the absence of information on the southern limit of G. rhomboides.

Rat Tail

Samples collected during the Sergipe Continental Slope Environmental Characterization Project coordinated by PETROBRAS (The Brazilian Petroleum Company) revealed a new species of the family Pseudotachidiidae Lang, 1936 (Copepoda, Harpacticoida), Pseudomesochra longiseta sp. nov. This is the first record of the genus Pseudomesochra T. Scott, 1902 for the South Atlantic. Pseudomesochra longiseta sp. nov. can be distinguished from all species of the genus Pseudomesochra by the presence of four sensilla on the rostrum and a very long terminal “rat-tail” seta on the second segment of the antenna. It shares with P. tamara Smirnov, 1946 the addition of one inner seta on the first exopodal segment of the swimming legs 2–4 (P2–P4), a character absent in the remaining species of the genus. Pseudomesochra longiseta sp. nov. is the fourth species described within this genus with 2-segmented P2–P4 endopods. The inclusion of the new species in Pseudomesochra requires the modification of some autapomorphic characters of the genus, the most important being the presence of four sensilla on the rostrum, a character shared with other Pseudotachidiidae.

A New Species

A new species of caprellid amphipod, Aeginella corallina sp. nov., is described from cold-water corals off Angola. This is the first observation of this genus in the South-Atlantic. The taxon is fully described and figured and is compared with the only known species of the genus, A. spinosa, occurring in deep waters of the northern hemisphere. Both species can be clearly differentiated on the basis of the following characters: (1) pereonite 1 is provided with a large dorsal acute projection in A. spinosa, while this projection is lacking in A. corallina; (2) gnathopod 2 propodus has an acute projection distally which is lacking in A. corallina; (3) the palm of the gnathopod 2 propodus in males is densely setose and it is provided with two distal projections in A. corallina while it is scarcely setose and with less developed projections in A. spinosa; (4) distal article of the mandibular palp is provided by a setal formula of 1-x-1, being x=10-12, in A. spinosa, while in A. corallina x=2-3, and the formula 1-x-1 is not so evident and it could be considered as 1-x-0.
