 en Acanthocollaritrema umbilicatum Travassos, Freitas & Buhrnheim, 1965 (Digenea: Acanthocollaritrematidae) from the common snook, Centropomus undecimalis, from Itamaraca, State of Pernambuco, Brazil

Acanthocollaritrema umbilicatum Travassos, Freitas and Buhrnheim, 1965,
is the only species of Acanthocollaritrematidae described up to the moment.
The systematic position of this species and the validity of the family has
been questioned by the possible presence of a gonotyl and a genital atrium
associated to the acetabulum. In this paper, specimens of this trematode,
collected from Centropomus undecimalis cultivated at Itamaraca,
State of Pernambuco, northeast Brazil, were studied under optical and
scanning electron microscopy, and compared with available sintypes. Gonotyl
and genital atrium were not observed and both family and species are
considered valid taxonomic entities. A. umbilicatum is redescribed
with the adition of new morphological information.
