Subsequently, many more specimens became available from N. albiflora that were studied using SEM. SEM studies showed many additional features that were not possible to discern with optical microscopy. These included the prominent angulation of the anterior trunk, the presence of (1) anterio-dorsal and (2) undulating mid-lateral fin-like protrusions of the body wall, uniquely shaped eggs as well as details of trunk micropores, proboscis, bursa, and female gonopore. Microscopical examination of eggs from the new collection demonstrated the presence of polar prolongation of fertilization membrane which places N. manubriensis in the subgenus Hebesoma. The features of trunk angulation, trunk fins, and egg morphology further distinguish N. manubriensis from all other species of Neoechinorhynchus Stiles and Hassall, 1905 from Vietnam or from any where else in the world.</p>10aAcanthocephala10aAnimals10aFemale10aFish Diseases10aHelminthiasis, Animal10aMale10aMicroscopy, Electron, Scanning10aPerciformes10aVietnam1 aAmin, O, M1 aHeckmann, R, A  uhttps://acanthocephala.myspecies.info/node/2502507nas a2200289   4500008004100000022001400041245017000055210006900225260001300294300001000307490000700317520163600324653001901960653001201979653001101991653001802002653001102020653002602031653003502057653000902092653001302101653001202114100001502126700001302141700001302154856005002167       2011                        eng d  a1252-607X00aFirst report of Neoechinorhynchus (Acanthocephala: Neoechinorhynchidae) from marine fish of the eastern seaboard of Vietnam, with the description of six new species.0 aFirst report of Neoechinorhynchus Acanthocephala Neoechinorhynch  c2011 Feb  a21-340 v183 a<p>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 pseudo-retractors 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 N. johnii because of proboscis armature and other discrepancies with the Yamaguti material. Notes on host distribution and feeding habits are also included.</p>10aAcanthocephala10aAnimals10aFemale10aFish Diseases10aFishes10aHelminthiasis, Animal10aIntestinal Diseases, Parasitic10aMale10aSeawater10aVietnam1 aAmin, O, M1 aHa, N, V1 aHa, D, N  uhttps://acanthocephala.myspecies.info/node/28
