	abstract = {<p>Neoechinorhynchus Stiles \&amp; Hassall, 1905 is revised based on both bibliographic studies and the examination of material. The evolution of the concept of the genus is discussed. The concept of Hebesoma Van Cleave, 1928 is also commented upon. The synonymy of the two genera is accepted, with Neoechinorhynchus having priority, and a new diagnosis for Neoechinorhynchus is provided. However, Hebesoma is recognised as a subgenus of Neoechinorhynchus, being differentiated from the nominal subgenus primarily on features of the egg. Of the 109 species studied, seven are transferred to other genera and 14 are considered invalid. Eleven species are assigned to the subgenus Hebesoma and 48 to the subgenus Neoechinorhynchus. Twenty-nine species were not assigned because of incomplete or absence of descriptions of adult females. Keys to assigned and non-assigned species are provided. Notes on the zoogeography of the 88 accepted species are also included.</p>

	abstract = {The para-receptacle structure (PRS) was first described in Neoechinorhynchus (Neoechinorhynchus) qatarensis Amin, Saoud, and Alkuwari, 2002 (Neoechinorhynchidae), as a prominent vesicle connected proximally to the anterior body wall and distally to the posterior wall of the proboscis receptacle then extending into the body cavity of males and females as a posterior conduit tube. The PRS has since been observed in Neoechinorhynchus (Neoechinorhynchus) golvani Salgado-Maldonado, 1978 (a new subgeneric diagnosis), and described in a member of another eoacanthocephalan family, Acanthogyrus (Acanthosentis) parareceptaclis Amin, 2005 (Quadrigyridae). In the latter species, a similar structure was also observed at the posterior end of the trunk. Our optical and transmission electron microscopy (TEM) observations in specimens of N. qatarensis show the PRS as a tandemly arranged set of nucleated cells delimited by a double-walled membrane and a muscular wall. It appears to be contractile with a secretory function related to changes in the hydrostatic pressure that may be associated with the extrusion and retraction of the proboscis in worms with weakly developed proboscis receptacle musculature. This is the first detailed study of the PRS and of its proposed function in the only 3 acanthocephalan species from which it has been identified to date. It is considered as an archaic structure present only in a few representatives of some primitive taxa having only a single-walled proboscis receptacle wall.},

(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. {\textcopyright} Springer 2005.},

	abstract = {Neoechinorhynchus (Neoechinorhynchus) buckneri n. sp. is described from the blacktail redhorse Moxostoma poecilurum (Jordon) (Catostomidae) in the Tchoutacabouffa River, Mississippi, U.S.A. It is the sixteenth species of Neoechinorhynchus Stiles and Hassall, 1905, with unequal lemnisci, and the sixth in a subgroup with dorsal body wall markedly thicker than ventral. Another species of the latter group, Neoechinorhynchus (Hebesoma) carinalus Buckner and Buckner, 1993, was also collected in the Tchoutacabuffa River, Mississippi, and tributaries of 2 other streams in Louisiana, U.S.A., from the sharpfin chubsucker, Erimyzon tenuis (Agassiz). All 3 streams from the 2 adjacent states discharge into the Gulf of Mexico. Most of these 16 species occur in North American freshwater fishes. Females of N. buckneri n. sp. are twice as long as males and their dorsal body wall is 4 times as thick as the ventral body wall, compared with 2.5 times as thick in males. All other shared structures are of similar size in both sexes. Proboscis armature is unremarkable, with hook circles being evenly spaced and hook sizes in each circle of similar size, but slightly decreasing in size posteriorly from 38-42 μm long anteriorly to 33-34 μm long at middle to 25 μm long posteriorly in both sexes. It is further distinguished from the group of 16 other species of Neoechinorhynchus with unequal lemnisci and body wall thickness, by having moderately but not extremely diverse leminisci, noncontiguous testes, and posterior testis distant from cement gland. A key distinguishing N. buckneri n. sp. from other species with different dorsoventral body wall thickness is provided. Scanning electron microscopy studies show the porous cuticular surface and the curling of the posterior end of breeding females caused by the contraction of the paired paravaginal muscles, among other features.},

	abstract = {The occurrence of acanthocephalans of the genus Neoechinorhynchus Stiles and Hassall, 1905 in Vietnamese waters is reported for the first time. Six new species are described from seven species of marine fish of the families Belonidae, Clupeidae, Megalopidae, Mugilidae, and Sciaenidae, collected in Halong Bay of the eastern seaboard of Vietnam in 2008 and 2009. These are Neoechinorhynchus (Neoechinorhynchus) plaquensis n. sp. characterized by dermal plaques covering the entire trunk; Neoechinorhynchus manubriensis n. sp. with very long anterior proboscis hooks having roots with prominent anterior manubria and very small and equal middle and posterior hooks, two pseudoretractors in the receptacle, simple vagina, and terminal gonopore; Neoechinorhynchus pennahia n. sp. with equal anterior and middle proboscis and somewhat smaller posterior hooks, and terminal female gonopore; Neoechinorhynchus ampullata with many giant nuclei in the body wall and lemnisci and a parareceptacle structure complex which includes pumping ampullas reported for the first time; Neoechinorhynchus (Neoechinorhynchus) longinucleatus n. sp. with very long giant nuclei in the Lemnisci, anteriorly twisted vagina, and subterminal female gonopore. Neoechinorhynchus (Neoechinorhynchus) ascus n. sp. is the second species of Neoechinorhynchus found with the parareceptacle structure/ampulla complex. Neoechinorhynchus (Neoechinorhynchus) johnii Yamaguti, 1929 of Bilqees, 1972 is not W johnii because of proboscis armature and other discrepancies with the Yamaguti material. Notes on host distribution and feeding habits are also included.},
