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/2502130nas a2200277   4500008004100000022001400041245014500055210006900200260001300269300000900282490000700291520130100298653001901599653001201618653001801630653001101648653001801659653001001677653003501687653002201722653001501744653000901759100001501768700001901783856005001802       1992                        eng d  a0022-339500aDescription and pathology of Neoechinorhynchus idahoensis n. sp. (Acanthocephala: Neoechinorhynchidae) in Catostomus columbianus from Idaho.0 aDescription and pathology of Neoechinorhynchus idahoensis n sp A  c1992 Feb  a34-90 v783 a<p>Neoechinorhynchus idahoensis is described from Catostomus columbianus caught in the Salmon River, Stanley Basin, Idaho. The new species is closest to Neoechinorhynchus venustus Lynch, 1936, but is distinguished from it by its smaller and variably structured eggs, anterio-dorsal trunk hump, bent and posteriorly notched proboscis receptacle, and larger proboscis, proboscis receptacle, and hooks. It is distinguished also from 2 other species of Neoechinorhynchus with proboscis hooks in middle and anterior circles about equally large and from 7 other species having lemnisci greatly unequal in length. Histopathology of host tissue showed limited host response exemplified by epithelial damage and hemorrhaging at point of proboscis attachment with subsequent macrophage and other phagocytic cell migration. The proboscis extended through the host epithelium into the submucosa with limited hemorrhaging at the point of attachment. Unorganized collagenous fibers were present. The lumen of the host intestine was obstructed, and compressed villi were present. The trunk of the worm damaged intestinal epithelium near the crypts, causing localized inflammation. The caryophyllaeid cestode Isoglaridacris calentinei Mackiewicz, 1974, was present in concurrent infections of C. columbianus.</p>10aAcanthocephala10aAnimals10aCypriniformes10aFemale10aFish Diseases10aIdaho10aIntestinal Diseases, Parasitic10aIntestinal Mucosa10aIntestines10aMale1 aAmin, O, M1 aHeckmann, R, A  uhttps://acanthocephala.myspecies.info/node/23
