Homalometron elongatum is reexamined using heat-killed material that was not subjected to pressure during fixation from Gerres cinereus collected from San Juan Harbor, Puerto Rico, U.S.A. The new material is compared with some paratype specimens and differs by having a much less variable forebody length, and a median rather than submedian genital pore. Tegumental spines reportedly cover the anterior end of the body but we observed tegumental spines covering the entire body surface in both the paratype and new material. Homalometron lesliorum n. sp. is described from Eucinostomus currani from the Pacific coasts of Costa Rica and Nicaragua. The new …

Two Cyclocoelids From The Lesser Yellowlegs, Tringa Flavipes (Scolopacidae), From The Central Flyway Of North America, Including The Description Of Haematotrephus Selfi N. Sp. (Digenea: Cyclocoelidae), Norman O. Dronen, Scott Lyell Gardner, F. Agustin Jimenez-Ruiz

Seven specimens of cyclocoelids (6 specimens representing Haematotrephus selfi n. sp. and 1 specimen representing a second unidentified species of Haematotrephus) collected by the late Dr. J. Teague Self, former professor, Department of Zoology, University of Oklahoma, Norman, Oklahoma, U.S.A., from the body cavities of 3 lesser yellowlegs, Tringa flavipes, (2 birds collected from Roger Mills County, Oklahoma on 23 and 29 August 1963, and 1 collected from Manitoba, Canada on 3 June 1964) and deposited in the Manter Laboratory of Parasitology, University of Nebraska, Lincoln, Nebraska are described. Haematotrephus selfi n. sp. can be distinguished from all …

Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.

The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …
