摘要

A new cryptogonimid trematode is described from the white crappie, Pomoxis annularis Rafinesque, 1818, collected from Lake Chotard, an oxbow lake directly connected to the Mississippi River in Issaquena County, and from a small ephemeral oxbow periodically connected with the Pascagoula River in Jackson County, both in Mississippi, U.S.A. Caecincola longiscens n. sp. is characterized by having an elongated body with a length to width ratio of 5.5-7.5:1, tandem testes, an elongated tubular seminal vesicle, and vitelline follicles confined to the hindbody.
