REMARKS
Rhinoxenus nyttus is apparently restricted to members of Anostomidae . The specimens analyzed here are similar to those described by Kritsky et al. (1988), except by the possession of a more extensive sclerotized cap on the root ventral anchor ( Fig. 1E View FIG ). The original description does not mention the presence of the brims of the MCO, observed in all studied specimens ( Fig. 1C, D View FIG ). Parasites of each host species present little variation in size in almost all the analyzed structures.
Rhinoxenus nyttus is characterized by possessing a ventral bar with lateral projections that serve as articulation to the ventral anchor; long chaliceshape vaginal vestibule; and ventral anchor with wavy point, representing 1/3 of the total length of the anchor.
