Resumen:
The morphology of the males of Neoechinorhynchus schmidti (Acanthocephala: Neoechinorhynchidae) is unknown, because this species was described based exclusively on females. However, recently we collected 2 common slider turtles Trachemys scripta in Centla swamps, Tabasco, Mexico, parasitized by 27 specimens of an acanthocephalan whose females were morphologically identical to N. schmidti. The domains D2 and D3 of the large subunit of the nuclear ribosomal RNA (LSU) of 3 males and 2 females of this material were sequenced. The sequences of both sexes were identical, and based on this result, we described for the first time the morphology of the males of N. schmidti. In addition, 6 sequences of a congeneric species, also parasite of turtles (Neoechinorhynchus emyditoides) were generated in the current research. The 11 sequences of these 2 species were aligned with 13 sequences of another 4 species of the same genus, producing a data set of 24 taxa with 674 nucleotides. The genetic diverg
