The genus numbers 72 valid species; twenty are indicated as <i>species inquirenda</i> because of poor descriptions and/or doubtful placement in the genus. Species of the genus were described from all oceans and latitudes. Of valid species, 64 ones (90%) were described from the tidal or upper subtidal zones, four species were recorded from the medium or lower shelf, and three species are abyssal. Thirty one species (43%) are known from Europe and the Northern Africa; 19 and 9 ones were described from South and North America (respectively); 8 ones were recorded from Asia; and 6 ones from the Australian region. The type species, <i>Paracanthonchus caecus</i> Mikoletzky 1924 has been recorded by a number of authors from various oceans around the World, yet many of these specimens have only roughly resembled the type description. Evidently, this species represents a complex of closely related species. Possibly, the same situation is in some other <i>Paracanthonchus</i> species, the repeated findings of which have no strong resemblance to type specimens. A tabular key to species is provided. A new abyssal species <i>Paracanthonchus mamubiae</i> from the Zenkevich Rise (North-Western Pacific, off North Japan, 5350 m depth) is described. The new species is characterized by: the tail, which is long with a thin, cylindrical terminal section; the absence of lateral differentiation of the cuticle; the presence of two groups of lateral pores (level of posterior part of pharynx and in cloacal region); one large dorsal tooth and two pairs of small subventral teeth combined with pharyngostomal cuticular ridges forming two denticles which may appear as a third pair of subventral teeth; 3–5 indistinct tubular preanal supplements; and a massive, proximally paired gubernaculum possessing broad flattened plates on each distal end. Each flattened gubernacular plate bears numerous (50–60) small cusps and one large process.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A revision of the genus <i>Paracanthonchus</i> (Cyatholaimidae, Nematoda) with a tabular key to species and a description of <i>P. mamubiae</i> sp. n. from the deep North-Western Pacific","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:38.518272","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"    18S rRNA; 28S rRNA; Cyatholaimidae; Deep-sea; New species; Kuril–Kamchatka Trench; Taxonomy; Pacific; Paracanthonchus; SEM; Tabular key; Zenkevich Rise; Zoogeography","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2017-01-06","DateCreate":"2017-01-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000348747400011","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.dsr2.2014.08.002"},"refs":null,"anarec":{"AnaID":282327,"PubliDate":2015,"Pagination":"104-118","XtraPublOfAnaID":null,"ISBN":null,"Volume":"111","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45197,"SerRR":"Deep-Sea Research, Part II.
