	abstract = {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.},

Specimens were most frequently encountered during the spring; the only two gravid females were recovered from Umbra limi, in early June. The same fish also serves as a transport host. A key separating F. tichiganensis from the four other known species in North America is presented. The new species most closely resembles F. friedi Nickol 1972 (= F. vancleavei haley and Bullock 1953), but can be separated from it by its longer proboscis which is armed with markedly more hooks per row, among other characteristics. Additional, new morphological observations are also reported.},

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.

	abstract = {<p>Echinorhynchus salmonis is a common parasite of salmoniform and other fishes, occurring in fresh and brackish waters throughout the Holarctic. Presented here is the first analysis of the morphometric and meristic variation in a Palaearctic population of E. salmonis, collected from whitefish Coregonus lavaretus L. and smelt Osmerus eperlaus (L.) from the Bothnian Bay, northern Baltic Sea. Morphological data were compared with published descriptions of congeneric taxa. Nearctic populations of salmonid echinorhynchids considered by some to represent a distinct species, E. coregoni Linkins in Van Cleave, 1919, did not show any morphological divergence from Palaearctic populations, indicating that the name E. coregoni should be suppressed. Similarly, E. alpinus Linstow, 1901 has been considered to be a junior synonym of E. salmonis. However, E. alpinus should be regarded as a valid species, because it has a longer and more elongate body. The armature of the acanthocephalan proboscis typically displays radial symmetry. However, in E. salmonis the hooks on the dorsal surface of the proboscis are smaller than those on the ventral surface. Size differences between dorsal and ventral hooks are most pronounced at the base of the proboscis. The systematic and functional significance of radial asymmetry of proboscis hooks is discussed.</p>
