New species of Aberrapex Jensen, 2001 (Cestoda: Lecanicephalidea) from eagle rays of the genus Myliobatis Cuvier (Myliobatiformes: Myliobatidae) from offArgentina

Three new species of Aberrapex Jensen, 2001 (Cestoda: Lecanicephalidea) have been collected from species of Myliobatis Cuvier along the coast of Argentina. Aberrapex ludmilae sp. n. parasitises M. goodei Garman in the San Matías Gulf. This species is unique in a combination of features including the...
