Acanthocephalus parksidei sp. n. is described from over 4,000 specimens recovered from 11 fish hosts in the Pike River, southeastern Wisconsin. A parksidei is a highly variable acanthocephalan which appears to present an intermediate form between the only 2 other members of the same genus, A. dirus and A. jacksoni, described from North American freshwater fishes. It is structurally similar to the larger A. dirus but is separated from it primarily by having fewer proboscis hook rows and hooks per row. It is separated from A. jacksoni on the basis of its slender body form, relatively larger size of male reproductive system in proportion to body size, as well as other features. It differs from the larger European A. lucii by having smaller proboscis hooks, different hook root shape, smaller proboscis receptacle, and smaller embryos.

Ecological associations of Acanthocephalus parksidei Amin, 1974, were studied in 11 southeastern Wisconsin fishes during 1972-73. Parasitic load was found to be related to host species, size (age), sex, concurrent infections, collection site, and season. Distribution in host intestine was related to the extent or intensity of infection, posterior migration, and concurrent infections. Parasitic cycle commenced in later summer-early autumn, peaked (in frequency and maturation) during the spring, and terminated in the late summer.

Pomphorhynchus bulbocolli Linkins in Van Cleave, 1919, was considerably more common in fishes of the river-connected Tichigan Lake than of the landlocked Silver Lake, southeastern Wisconsin. It is reported from 17 species of principal, accessory, and occasional definitive hosts (new record in Moxostoma carinatum) and from 13 species of paratenic hosts (new records in Amia calva, Ictalurus punctatus, Lepomis cyanellus, and Pomoxis nigromaculatus). Infection patterns were influenced by fish species, feeding behavior, temperature, availability of intermediate host, type of water body, fish movement, and changes in fish host community. Host roles are not fixed but are often interchangeable. A seasonal cycle in prevalence, intensity, and maturation was evident, with greatest abundance and maturation during summer and recruitment during summer and autumn. Recruitment of new infections, development, and release of eggs, however, occurred all year. Sex ratio changed from near equal in new infections to one more highly in favor of females in older adults. Female fish were considerably more frequently and heavily infected than males. No relationship with fish age (size) was evident. Worms were mostly attached in posterior intestinal locations but initial establishment sites correlated with temperature. Translocation of P. bulbocolli due to competitive exclusion in concurrent infections was not observed. The significance of extraintestinal larval forms in the cycle of transmission was noted.
