Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae), a new free-living marine nematode from the Condor Seamount (North-East Atlantic Ocean)

Epsilonematids are epifaunal nematodes characterized by an epsilon-shaped body and the presence of ambulatory setae, which are used in their locomotion. Nematodes belonging to this family were recently found in deep sea, especially in cold-water coral and seamount ecosystems. Akanthepsilonema oceanopolis sp. nov. (Nematoda: Epsilonematidae) is described from sediments of the Condor Seamount (North-East Atlantic Ocean) at 206 m water depth. Its main features are a heterogeneous cuticule with large horn-like dorsal spines both in anterior and in posterior regions; the presence of eight subcephalic setae arranged in two rows and the ratio maximum/minimum body diameter larger than two. The taxonomic position of this new species within the genus is discussed...

Background Nematodes are an important component of deep-sea hydrothermal vent communities, but only few nematode species are able to cope to the harsh conditions of the most active vent sites. The genus Oncholaimus is known to tolerate extreme geothermal conditions and high sulphide concentrations in shallow water hydrothermal vents, but it was only occasionally reported in deep-sea vents. In this study, we performed morphological, genetic and ecological investigations (including feeding strategies) on an abundant species of Oncholaimus recently discovered at Lucky strike vent field on the Mid-Atlantic Ridge at 1700 m water depth. Results We described this species as Oncholaimus dyvae sp. nov.. This new species differs from all other members of the genus...

Glochinema bathyperuvensis sp. n. (Nematoda, Epsilonematidae): A new species from Peruvian bathyal sediments, SE Pacific Ocean
Provedor de dados: 16
Autores: Neira, Carlos; Gad, Gunnar; Arroyo, Nina L.; Decraemer, Wilfrida.
Glochinema bathyperuvensis sp. n., the first record of Epsilonematidae from bathyal muddy sediments of the oxygen minimum zone (OMZ) off Callao, Peru (eastern Pacific Ocean) is described. The new species belongs to the subfamily Glochinematinae and is characterized by the possession of more than 8 pairs of subdorsal thorns asymmetrically arranged and a single dorsal one in the pharyngeal region, as well as by the presence of ten to thirteen blade-like cuticular protrusions forming a latero-dorsal palisade around the posterior head region and anterior cervical region. In addition, G. bathyperuvensis is characterized by its large size, more than 240 cuticular annules, provided with an extremely dense „hairy“ body ornamentation and, four rows of ambulatory...
