(Acanthocephala: Neoechinorhynchidae) is described from the dusky kob, Argyrosomus japonicus (Temminck & Schlegel) from the southern coast of South Africa in the Breede River Estuary. Like four other species of Neoechinorhynchus Stiles & Hassall, 1905, N. (N.) africanus Troncy, 1969, N. (N.) johnii Yamaguti, 1939, N. topseyi Podder, 1937 and N. (N.) tylosuri Yamaguti, 1939, the new species has a very long, slender body, cylindrical testes and cement-gland, anterior proboscis hooks much longer than the middle or posterior hooks, and a long neck. The new species is the only species of Neoechinorynchus having an antero-dorsal hump just posterior to the neck and a specialised vaginal sphincter and a gonopore on the dorsal side. It is closest to N. (N.) johnii, but is distinguished from it by: the size of the trunk, proboscis, anterior proboscis hooks, neck, and the posterior testis in relation to the cement-gland; the shape of cerebral ganglion and proboscis hook root; and the number of giant nuclei in the cement-gland.</p>10aAcanthocephala10aAnimals10aMale10aPerciformes10aRectum10aRivers10aSeasons10aSouth Africa1 aAmin, Omar, M1 aChristison, Kevin, W  uhttps://acanthocephala.myspecies.info/node/3502310nas a2200289   4500008004100000022001400041245026000055210006900315260001300384300001100397490000700408520135300415653001901768653001201787653001301799653001101812653001801823653001101841653001601852653002601868653001501894653001001909653000901919653002401928100001801952856005001970       2005                        eng d  a0165-575200aOccurrence of the subgenus Acanthosentis Verma & Datta, 1929 (Acanthocephala: Quadrigyridae) in Japan, with the description of Acanthogyrus (Acanthosentis) alternatspinus n. sp. and A.

These include two new species, Acanthogyrus (Acanthosentis)alternatspinus n. sp. from Rhodeus ocellatus ocellatus (Kner) (Cyprinidae) and A. (A.) parareceptaclis n. sp. from Cobitis biwae Jordan & Snyder (Cobitidae) in the Lake Biwa drainage, Japan. These are the first representatives of the subgenus Acanthosentis recorded from Japan. Most other species are found in the Indian subcontinent, but a few have been reported from China, elsewhere in Asia, Africa, Europe and Central America. Only A. (A.) alternatspinus has the lateral proboscis hooks in the apical and middle circles markedly displaced posteriorly but of equal size to the other hooks in the same circles and multi-branched lemnisci. Acanthogyrus (A.) parareceptaclis uniquely possesses parareceptacle structures in both sexes as well as a pair of cone-shaped genital jackets flanking the vagina (vaginal sleeve). Two new names are provided: Acanthogyrus (Acanthosentis) adriaticus nom. nov. for A. (A.) lizae Orecchia, Paggi & Radujkovic, 1988 nec Wang, 1896, and A. (A.) cheni nom. nov. for A. (A.) coiliae (Yamaguti) sensu Chen et al. (1973). A review of the species composition of Acanthosentis is provided and a key to its species and zoogeographical notes are included.</p>10aAcanthocephala10aAnimals10aDrainage10aFemale10aFish Diseases10aFishes10aFresh Water10aHelminthiasis, Animal10aIntestines10aJapan10aMale10aSpecies Specificity1 aAmin, Omar, M  uhttps://acanthocephala.myspecies.info/node/36
