Abstract
The echinostomatid trematodeEchinochasmus leopoldinae n. sp. is described on the basis of adults found in the intestine of chicks and mice experimentally infected with metacercariae from the gills of the cichlid fishesCichlasoma urophthalmus andC. synspilum from the Peninsula of Yucatan.E. leopoldinae, which had previously been misidentified asE. zubedakhaname Nasir & Díaz, 1968, is characterised by the presence of 20 collar spines with one angular spine on each side and vitelline follicles confluent in the posterior part of the body. A differential diagnosis ofEchinochasmus species possessing 20 collar spines is provided, and the developmental stages (redia, cercaria, metacercaria and adult) ofE. leopoldinae are described.
