Fourteen new species of freeliving interstitial marine nematodes are described from sandy habitats in the Exe estuary area, South Devon. They are all referable to existing genera. Enoplolaimus denticulatus sp. nov. is similar to E. connexus Wieser, 1953, but differs from it principally in the shorter cervical setae of the female, and in the form of the spicules in the male; Mesacanthion africanthijorme sp. nov. is characterized by the absence of a pre-cloacal supplement, by the presence of… 

New species of Epacanthion (Nematoda: Thoracostomopsidae) from Patagonia coast, Río Negro and Chubut, Argentina

Two new free-living marine nematodes belonging to the family Thoracostomopsidae, subfamily Enoplolaiminae and the genera Epacanthion are described from Patagonian coastal areas, Río Negro and Chubut

Nematode associations in the Exe estuary

A study of the distribution of nematodes in the Exe estuary was planned to cover as wide a spectrum of physical and chemical conditions as possible, and a large proportion of the species found were new British records, and some new to science.

Spirobolbolaimus undulatus sp. nov. in intertidal sediment from the East China Sea, with transfer of two Microlaimus species to Molgolaimus (Nematoda, Desmodorida)

The diagnosis of the genus Spirobolbolaimus is emended based on the description of the new species, which is characterized by six jointed outer labial setae much thicker and longer than the four slender cephalic setae, anterior and posterior pharynx bulbs, sclerotized multispiral amphid fovea, eight longitudinal rows of postamphideal setae and many precloacal supplements.

New nematode species from the continental slope of New Zealand (Chromadorea, Microlaimida, and Chromadorida), and unexpected placement of the genus Molgolaimus Ditlevsen, 1921

Congruence analysis suggests that in some cases at least, the structure of the female reproductive system is a more taxonomically informative trait for marine nematode classification than the male reproductive system or cuticle.

New Spirinia and Stygodesmodora species (Nematoda, Spiriniinae) from the Southwest Pacific, and a revision of the related genera Spirinia, Chromaspirina and Perspiria

Two new species of the family Desmodoridae are described from the upper continental slope of New Zealand, Southwest Pacific, and the genera Spirinia, Chromaspirina and Perspiria are revised to eliminate overlap in the definitions of these genera.

The Contrasting Ecology of Free-Living Nematodes in Macrotidal and Microtidal Estuaries

This paper compares the diversity, distribution and trophic composition of the nematode assemblages in the intertidal sediments of the macrotidal Exe Estuary (UK) and the shallow subtidal sediments

Swedish Plectida (Nematoda). Part 4. The genus Leptolaimus de Man, 1876.

Nine new species of Leptolaimus are described from bottom sediments collected in marine habitats of Sweden, including the Bothnian Sea and Bothnian Bay, the Baltic Sea proper, Gullmarn Fjord and the Skagerrak while three have been previously recorded in Sweden while nine are new records for the Swedish fauna.

Bibliographic revision of Mesacanthion Filipjev, 1927 (Nematoda: Thoracostomopsidae) with description of a new species from Jeju Island, South Korea

A new species of the genus Mesacanthion Filipjev, 1927 was discovered during a survey of natural beaches of Jeju Island in South Korea. The new species Mesacanthion jejuensis sp. nov. shares general

The state of the art of Xyalidae (Nematoda, Monhysterida) with reference to the Brazilian records

Xyalidae is typically encountered in oceanic sandy beaches, with only the species belonging to Daptonema, Theristus, Trichotheristus and Zygonemella being recorded in estuarine sediments, suggesting that the colonization of inland waters occurred multiple times along the evolutionary history.

Description of a new species of Epacanthion (Thoracostomopsidae, Nematoda) from Brazil and a modified key for species identification*

The main features are: the long spicules, the absence of gubernaculum, and the presence of three pairs of setae in the tail region of Epacanthion agubernaculus sp.
