Two New Species

The aim of this study is to solve taxonomic problems pertaining to Spio filicornis (O.F. Müller, 1776). The original description by O. F. Müller was very brief and type material was not deposited. Based on the literature the confusion about the identity of the species has been tremendous; e.g., it was only recently realized that at least two different species from the North and Baltic Seas could be identified as S. filicornis (Bick et al. 2010). The present study is based on material collected by the authors in 2009 at the type locality in Iluilârssuk, near Paamiut, SW Greenland. Spio filicornis is redescribed in detail and illustrated comprehensively. A neotype has been designated and deposited in the collection of Rostock University. Species formerly referred to as S. cf. filicornis from the North and Baltic Seas (Bick et al. 2010) are formally described as two new species, Spio arndti sp. nov., and S. symphyta sp. nov. The morphological diagnostic characters within Spio are discussed. Information on three molecular markers (16S rDNA, 18S rDNA, cytochrome c oxidase subunit I) is also provided. The genetic divergence between the three Spio species corroborates the taxonomic discrimination.

The Rich

In the course of dredging for the rich epifauna of the continental slope near 48° 30′N., 10° W. (Southward & Southward, 1958b) in May 1957, several hauls were made by chance on a muddy bottom at 500–700 fin. depth. At the time, these hauls were examined only cursorily after sieving, and the con-tents immediately preserved. One of the hauls contained several damaged siliceous sponges, and a recent careful examination disclosed a number of pogonophore tubes entangled among the threads and spicules of the sponges.

Two New Species

In May 1958 it was thought that all species of Pogonophora so far discovered in the north-east Atlantic belonged to the genusSiboglinumCaullery (Southward & Southward, 1958). Since then I have had the opportunity of examining further collections from deep water off the British Isles and Spain. At least two species of multitentaculate pogonophores have been discovered, and re-examination of some material collected in May 1958 shows that one of the species was also present in these collections. Although considerable material belonging to other species remains to be worked up it has been thought worth while to describe these two species first. One is widespread and can be locally abundant, while the other is the largest pogonophote so far found in the Atlantic. Both are the first Atlantic representatives of their respective genera.

P Type

One new dorvilleid species belonging to the genusOphryotrochaClaparède & Mecznikow, 1869 is described. The studied material was collected in circalittoral seabeds (70–100 m depth) in the Cantabrian Sea (north-east Atlantic Ocean). The new speciesOphryotrocha cantabricais characterized by having well-developed antennae and palps, parapodia with long dorsal cirrus, sub-triangular acicular lobes and inferior chaetal lobe well-developed, as well as the presence of P-type maxillae and bifid mandibles slightly tagged. The most closely relatedOphryotrochaspecies areO. longidentataJosefson, 1975 andO. lobiferaOug, 1978; however, both species have biarticulated palps. Other differences withO. cantabricasp. nov. are: body size and shape, parapodia morphology and number of setae, as well as the shape of mandibles and maxillae.

A New Species

A new species of Ischnomesidae (Crustacea: Isopoda: Asellota), Haplomesus longiramus sp. nov. is described from the Bay of Biscay. This species is unusual due to the presence of long, thin anterolateral projections supporting the antennae and an elongate pereonite 4. These features are also seen in Haplomesus biscayensis Chardy, 1975, and the two species closely resemble each other. The presence of a laterally directed spine on pereonite 5 of the male of Haplomesus longiramus sp. nov. along with the elongate uropods of both male and female easily differentiates this species from H. biscayensis. Within its known distributional area, this new Haplomesus species inhabits bathyal muddy bottoms from 500–1009 m, with a maximum abundance of 29 individuals per 100 m 2 recorded at approximately 700 m.
