A New Species

A new heterotardigrade, Bryodelphax aaseae sp. nov. is described from a small moss sample collected in the Rano Kau Crater on Easter Island (Rapa Nui) in 1989. The new species belongs to the group of species within the genus that have ventral plates. B. aaseae sp. nov. is similar to B. weglarskae (Pilato, 1972), B. sinensis (Pilato, 1974) and B. iohannis Bertolani, Guidi & Rebecchi, 1995 but differs from them mainly by a different number and arrangement of ventral plates. This is the first record of the genus Bryodelphax from Easter Island/Rapa Nui.

A New Species

A new species of kamakid amphipod, Ledoyerella kunensis sp. nov., is described from waters off Namibia and Angola. This is the first record of this genus in the Atlantic. The taxon is fully described and figured and is compared with the other known species of the genus occurring in waters of the Indian and Pacific Ocean.

A New Species

The new Hexactinellid sponge Chaunoplectella megapora sp. nov. reported in this study was collected from the COMRA contract area, the western part of Clarion-Clipperton Fracture Zone (CCFZ) in the eastern Pacific Ocean at a depth of 5258 m. This sponge’s extraordinary multiporous body with the presence of unique codonhexasters, sigmatocomes, toothed discohexasters and hemidiscohexasters, as well as stellate disocohexasters, characterizes it as a new species in the genus Chaunoplectella. This report presents the first record of family Leucopsacidae at this site in the eastern Pacific Ocean.

A New Species

A new heterotardigrade, Echiniscus barbarae sp. nov., is described from a moss sample collected in Cuba. This species belongs to the ‘arctomys group’, which contains many problematic species. The new species differs from the most similar species Echiniscus limai mainly by having cephalic, scapular and terminal dorsal plates not faceted. This paper is the first record of Tardigrada from Cuba.

A new species of Trischizostoma collected at depths of 1392–1420 m from western Mexico is described. It represents the first record of the genus in the NE Pacific. The new species is morphologically similar to T. circulare, T. tohokuense and T. richeri. These species all share a large rostrum, expanded eyes and an entire telson. Distinctive characters of the new species include a dorsally unnotched urosomite 1, a subconical coxa 2, a subtriangular propodus of gnathopod 1, a single seta and one protuberance on the palm of gnathopod 2, the presence of 10 spine-teeth in the outer plate of maxilla 1 and of a large, 1-articulate maxilla 1 palp, and the telson with 2 minute simple setae and 2 minute projections distally.

A new species of the perchlet genus Plectranthias is herein described from a single specimen found at Rapa Nui (Easter Island) in the South Pacific. Plectranthiasahiahiata sp. n. was collected at a depth of 83 m in a mesophotic coral ecosystem at Rapa Nui. The main difference between Plectranthiasahiahiata and other members of the genus is higher fin-ray counts (X, 18 dorsal; 18 pectoral) and its distinctive coloration. Compared to the three other known eastern South Pacific species, P.ahiahiata has more dorsal-fin rays, more pectoral-fin rays, fewer tubed lateral-line scales, fewer gill rakers, a longer head relative to SL, a very short first dorsal spine relative to SL, and a short third anal spine relative to SL. Plectranthiasahiahiata is distinguished from western Pacific species, by having more dorsal- and pectoral-fin rays. The closest relative based on genetic divergence (with 12.3% uncorrected divergence in the mitochondrial COI gene) is Plectranthiaswinniensis, a widely distributed species, suggesting important links between Rapa Nui and western Pacific islands. This new species adds to the high endemism of the Rapa Nui ichthyofauna, and is further evidence of the importance of mesophotic reefs as unique communities.
