Discovery of Novocriniidae (Copepoda, Harpacticoida) from cold-water corals in the Porcupine Seabight (NE Atlantic), with description of a new species of Atergopedia Martínez Arbizu & Moura, 1998

The first deep-sea representative of Halophytophilus Brian, 1919 is described from samples of dead cold-water coral fragments, glass sponge skeletons and underlying sediment collected from the Porcupine Seabight (NE Atlantic). Halophytophilus lopheliae sp. nov. can be distinguished from its congeners by the dimensions of the P1 endopod and the position of the inner seta on its proximal segment. Moreover, we present the first description of a male in this genus. The occurrence of Halophytophilus and three other ectinosomatid genera with prehensile first legs is remarkable in the deep sea and an indication that the hard substrates of the coral degradation zone may provide an exceptional habitat. A key to the five species of Halophytophilus is included.

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.

A New Species

Diapirs and mud volcanoes (MVs) are formed by the migration and extrusion of fluids and mud to the seafloor, respectively. In the Gulf of Cádiz there are ca. 60 MVs and several diapirs with different environmental conditions and seepage activity. Previous studies, mainly on MVs, have demonstrated that the invertebrate fauna associated with these seafloor structures can be very diverse, including chemosymbiotic species, mostly mollusks and frenulate polychaetes, as well as vulnerable suspension feeders, such as cold-water corals and sponges, among others. Previous studies of the bryozoan fauna in this area have recorded species belonging to 28 families. One of these families is Phidoloporidae, which comprises 27 genera worldwide, including the common Rhynchozoon, Reteporellina, and Reteporella. In the present study, two species belonging to Reteporella are redescribed, and a new species is described from diapirs and MVs on the shelf and slope of the Gulf of Cádiz. The samples were collected during several oceanographic expeditions carried out by the Instituto Español de Oceanografia. This genus is well represented in the NE Atlantic Ocean and the Mediterranean Sea, and our study extends its occurrence on MVs and diapirs fields of the Gulf of Cádiz.

A new deep-sea stalked barnacle, Ashinkailepas kermadecensis sp. nov. has been recovered from a cold-water seep at depths of 1165 metres in the vicinity of the Kermadec Ridge to the northeast of the North Island, New Zealand. There are now two species of Ashinkailepas—the other, Ashinkailepas seepiophila Yamaguchi, Newman & Hashimoto, 2004, occurs in deep, cold seeps off central Japan. As there are two species within Ashinkailepas, formal diagnoses are provided for both taxa.

Dendronotus patricki, sp. nov. is a new species collected from a whalefall in the Monterey Canyon, California. This new species is characterised by having a small number of dorsal appendages compared with similarly sized species of Dendronotus Alder & Hancock, 1845. Anatomically, D. patricki, sp. nov. has a small prostate with just a few alveoli, a very small seminal receptacle situated near the distal end of the vagina, and a relatively short and small ampulla. The rachidian radular teeth of D. patricki, sp. nov. are unique among Dendronotus as they have a well differentiated, conical cusp with very small denticles on either side, but most denticles are located on the sides of the teeth, rather than on the sides of the cusp. Dendronotus patricki, sp. nov., is genetically distinct from other species of Dendronotus for which sequence data are available. A phylogenetic analysis of Dendronotus based on COI, 16S, and H3 sequence data reveals that D. patricki, sp. nov. forms a polytomy with Dendronotus orientalis (Baba, 1932) and a clade of the shallow temperate and cold water species. The tropical Indo-Pacific species D. regius Pola & Stout, 2008 is the sister group to all other Dendronotus species.

A New Species

Newtoniellinae is a worldwide marine group of cold-water, deep-sea species, comprising the genera Cerithiella, Paramendax and Trituba. Prior to this study, the subfamily was represented in Brazil by four species of Cerithiella. The present contribution adds new Brazilian records of two of these species, Cerithiella amblytera and Cerithiella enode, in addition to new records of two species previously known only from Cuba and the south-eastern USA, respectively: Cerithiella sigsbeana comb. nov. and Cerithiella producta. Two new species of Cerithiella from Brazil are described: Cerithiella atali sp. nov. has a pointed protoconch identical to the species described in the previously synonymized genus Stilus; Cerithiella candela sp. nov. has the teleoconch very similar to Cerithiella pernambucoensis, but is differentiated by the protoconch morphology. Also, a new species of Trituba is described, Trituba anubis sp. nov., which is the second species of this genus recorded for the western Atlantic. Eumetula axicostulata comb. nov. and Eumetula vitrea comb. nov., both from the western Atlantic but not recorded from Brazil, are transferred from the genus Cerithiella. This study increases from four to nine the number of known species of Newtoniellinae from Brazil.

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.
