Abstract

Eleven specimens of a new genus of cyclocoelid, Selfcoelum limnodromi n. gen., n. sp. (Digenea: Cyclocoelidae: Cyclocoelinae) from the air sacs of a long-billed dowitcher, Limnodromus scolopaceus, collected from the Cheyenne bottoms in Oklahoma and deposited at the Howard W. Manter Laboratory, University of Nebraska by Dr. Teague Self, former professor, Department of Zoology, University of Oklahoma, Norman, Oklahoma were examined. The new genus has an intertesticular ovary placing it in Cyclocoeolinae. It is most similar to species of Morishitium and Neohyptiasmus in having a postpharyngeal genital pore and vitelline fields that are not confluent posteriorly. However, unlike species of either of these 2 genera, the ovary of S. limnodromi n. gen., n. sp. forms a triangle with the testes as is found in species of Cyclocoelum where the genital pore is prepharyngeal rather than postpharyngeal. Selfcoelum n. gen. further differs from Morishitium by having uterine loops that surpass the ceca and vitelline fields laterally approaching the body wall instead of being intercecal, and from Neohyptiasmus by having testes that are rounded and entire instead of being lobed. A revised key to the Cyclocoelinae is provided to include the 2 additional genera that have been recently described from North America, Neoallopyge and Selfcoelum.
