Abstract
Una especie nueva del género Paradoneis Hartman, 1965 (Annelida, Paraonidae) ha sido identificada en fondos blandos del País Vasco (NE de la península Ibérica, SE del golfo de Vizcaya). La nueva especie se caracteriza principalmente por su pequeña talla, tres segmentos setígeros prebranquiales, cinco (excepcionalmente seis) pares de delgadas branquias simples, notosedas modificadas liriformes, y una región pigidial con siete cirros. En el presente artículo se realiza una descripción, ilustración y discusión de la nueva especie, aportándose también información sobre su ecología y distribución. Complementariamente, se aporta una clave de identificación de todas las especies conocidas de Paradoneis. El Material Tipo ha sido depositado en el Museo Nacional de Ciencias Naturales, Madrid.
Highlights
Sample collection and analysisThe paraonids represent a family of elongate, small polychaetes with numerous segments
The Type Material has been deposited in the Museo Nacional de Ciencias Naturales, Madrid
They are deposit-feeders and can be found from the littoral zone to abyssal depths (Glasby, 2000), not having been found in fresh water. This family includes about 156 species distributed in eight genera: Aparaonis Hartman, 1965, Aricidea Webster, 1879, Cirrophorus Ehlers, 1908, Levinsenia Mesnil, 1897, Paradoneis Hartman, 1965, Paraonides Cerruti, 1909, Paraonis Grube, 1873 and Sabidius Strelzov, 1973
Summary
The paraonids represent a family of elongate, small polychaetes (up to 40 mm long) with numerous segments. They are deposit-feeders and can be found from the littoral zone to abyssal depths (Glasby, 2000), not having been found in fresh water. Nowadays, this family includes about 156 species distributed in eight genera: Aparaonis Hartman, 1965, Aricidea Webster, 1879, Cirrophorus Ehlers, 1908, Levinsenia Mesnil, 1897, Paradoneis Hartman, 1965, Paraonides Cerruti, 1909, Paraonis Grube, 1873 and Sabidius Strelzov, 1973. During two sampling campaigns recently carried out on the continental shelf of the Basque coast (SE Bay of Biscay), a new species of Paradoneis is described, illustrated and compared with the currently known species of the genus
