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.},

Several nominal species have been shown to represent complexes of morphologically cryptic biological species, a situation potentially confounding the analysis of ecological data. A software tool, \&$\#$39;Proboscis profiler\&$\#$39;, was developed to detect morphological heterogeneity in collections of superficially similar acanthocephalan worms based on the multivariate statistical analysis of proboscis hook dimensions. Proboscis profiler identifies objective, natural groups in a collection of acanthocephalans which may correspond to distinct biological species or populations. Initial trials demonstrate that Proboscis profiler can discriminate biological acanthocephalan species of the Echinorhynchus gadi Zoega in M\&uuml;ller, 1776 complex and differentiate between dorsal and ventral hook rows from the proboscis of E. salmonis M\&uuml;ller, 1784.

	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>
