A New Species

A new species of Neostygarctus Grimaldi de Zio et al., 1982 is described from the Great Meteor Seamount summit plateau in the Northeast Atlantic. Neostygarctus grossmeteori sp. nov. is characterized by the number and position of dorsomedian spines (five spines on the cephalic plate and each body plate and on the caudal plate, the spines decreasing in length backwards); the presence of eyes and of one or two pairs of ventral cervical spines; a transversal row of two to five short but strong spikes on the ventral side of the lateral body processes; only the internal claws of each leg provided with a normal accessory spine. The new species is related to N. acanthophorus Grimaldi de Zio et al., 1982 but differs by details of the dorsal body spines and the sculptures, the presence of ventral neck spines and ventral spikes on lateral body projections. Neostygarctus grossmeteori sp. nov. differs from two other known species of Neostygarctus, N. oceanopolis Kristensen et al., 2015 (Condor Seamont, NE Atlantic) and N. lovedeluxe Fujimoto & Miyazaki, 2013 (submarine cave NW Pacific), even more obviously by the number and position of dorsal body spines.

A New Species

Leiopathes montana, a new species previously reported as L. glaberrima (Esper), is described from the plateau of the Great Meteor seamount (North Atlantic) at depth 300–335 m. The new species can be easily distinguished from all other species of the genus by very thin at tips, slightly bended terminal branchlets 0.15–0.2 mm in diameter above the base, rather long in comparison to the size of the colony, small compressed triangular spines 0.02–0.03 mm long and 0.22–0.5 mm apart, and small densely-set polyps (6–9 per centimeter). Eight species assigned to the genus Leiopathes represent two distinct groups: (1) sparsely branched forms with longer terminal branchlets (L. glaberrima, L. valdiviae, L. acanthophora, L. bullosa, L. montana), and (2) forms with sinusoidal stem and branches, and very short branchlets forming flabellate fronds (L. expansa, L. grimaldii, L. secunda). The largest in size syntype of L. grimaldii Roule, 1902 collected off the Azores is proposed here as the lectotype, since it is the only full grown and complete specimen and also the only specimen illustrated and described in detail by Roule.

Abstract Carreiro-Silva, M., Braga-Henriques, A., Sampaio, I., de Matos, V., Porteiro, F. M., and Ocaña, O. 2011. Isozoanthus primnoidus, a new species of zoanthid (Cnidaria: Zoantharia) associated with the gorgonian Callogorgia verticillata (Cnidaria: Alcyonacea). – ICES Journal of Marine Science, 68: 408–415. In the Azores, Northeast Atlantic, an undescribed epizoan zoanthid is often found in association with the cold-water gorgonian Callogorgia verticillata at 110–800 m depth. This zoanthid was identified as a new species, Isozoanthus primnoidus sp. nov., based on morphological and anatomical characters of the polyps and type of cnidae. The distinguishing features of I. primnoidus are coenenchyme, column, and oral disc light brown, with short, translucent tentacles. Contracted polyps have column diameter up to 3 mm and height up to 2 mm. Ectoderm and outer mesogloea are densely encrusted with mineral particles and gorgonian sclerites. Capitulum bears a maximum of 14 distinctive ridges. Isozoanthus primnoidus was associated with 17% of C. verticillata colonies studied, and covered 14 ± 5% of the gorgonian colony. There was strong evidence of a parasitic relationship whereby I. primoidus progressively eliminates gorgonian tissue and uses the gorgonian axis for structure and support, and sclerites for protection.

A new sphyrapodid tanaidacean,Sphyrapus caribensissp. nov. is described and a new record ofKudinopasternakia siegiis reported for the Colombian Caribbean based on samples collected during cruises in 2014–2015. The new species appears to be most closely related to the northeast Atlantic species,Sphyrapus malleolus. Sphyrapus caribensiscan be distinguished fromSphyrapus malleolusby a combination of characters, including the maxillipedal basis without long distal seta, the number of setae on the distoventral margin of pereopods 1 and 2, and the number of plumose seta on the pleopod basis. A key for the separation ofSphyrapusspecies is presented.

Synoptic Table

In the Northeast Atlantic several polynoid species have been confused in the past due to similarities in their elytral characters: Harmothoe globifera (G.O.Sars, 1873), Eunoe nodosa (M. Sars, 1861), Eunoe oerstedi Malmgren, 1866, Leucia nivea (M. Sars, 1863), and Acanthicolepis zibrowii n. sp., a new species from deep cold-water corals. The five species are redescribed and figured based on type and additional material. An identification key allowing also the identification of juveniles and anterior fragments and a synoptic table listing the major distinguishing characters of the species covered are provided.
