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.
