Cestodes found to represent previously undescribed members of the genus Hymenolepis s.str. (Yamaguti 1959) were recovered from pocket gophers, Geomys bursarius (Shaw), in northeastern Colorado. Hymenolepis weldensis n.sp. and Hymenolepis geomydis n.sp., not occurring together in any individual host, were found in 3 and 8%, respectively, of pocket gophers examined for helminths. The life cycle of H. weldensis was completed in the laboratory using beetles, Tenebrio molitor (L.), as intermediate hosts, and pocket gophers of three genera (Geomys, Thomomys, and Pappogeomys) as definitive hosts. Development of H. weldensis did not occur in laboratory rats, Rattus norvegicus (Berkenhout). Morphologic relationships four species of Hymenolepis (H. diminuta, H. tualatinensis, H. weldensis, and H. geomydis) were analyzed using multiple discriminant function analysis, which clearly allocated individual cestodes to the respective groups and discriminated species.

Geomys Bursarius

Plains pocket gopher, Geomys bursarius, a grassland inhabitant, is common among the mammal taxa identified on the southeast Ozark margin at the Lepold site, 23RI59, Ripley County, Missouri. Its presence throughout the midden depth, whether an incidental inclusion or human prey, implies that a favorable habitat existed in the immediate vicinity. As radiocarbon dates indicate midden deposition began about 7500 radiocarbon years before present, grassland was a component of the local vegetation beginning in the middle Holocene, if not before.

Between 4 February and 28 June 1973, 45 plains pocket gophers, Geomys bursarius illinoensis (24) and G. b. missouriensis (21), were examined for ectoparasites. A total of 45 273 arthropods (Acari unless designated otherwise) was collected from G. b. illinoensis in Illinois in the following order of decreasing abundance: Geomylichus floridanus, Geomydoecus illinoensis (chewing louse), Androlaelaps geomys, Euschongastia trigenuala, Echinonyssus longichelae, Pergamasus sp., E. geomydis, Oribella sp., Ixodes sculptus, Pygmephorus scalopi, Dendrolaelaps sp., Pygmephorus sp., Parasitus sp., Ctenophthalmus pseudagyrtes (flea), Cyrtolaelaps sp., Macrocheles sp., Anoetidae, Haemogamasus reidi, Imperipes (I.) spickai, Pygmephorus designants, P. spickai, P. whitakeri, and Scutacarus geomyi. A total of 34 504 arthropods (Acari unless designated otherwise) was collected from G. b. missouriensis in Missouri in the following order of decreasing abundance: Geomydoecus spickai (chewing louse), Geomylichus floridanus, Echinonyssus geomydis, Androlaelaps geomys, Euschongastia trigenuala, Macrocheles sp., Echinonyssus longichelae, Pergamasus sp., Dendrolaelaps sp., Pygmephorus sp., Oribella sp., Saproglyphidae, Pygmephorus scalopi, P. whitakeri, Anoetidae, Cyrtolaelaps sp., Parasitus sp., and Scutacarus missouriensis.
