Neoechinorhynchus schmidti n. sp. is described from the red-eared slider, Trachemys scripta elegans, from the state of Tabasco, Mexico. A large, prominent process at the posterior end of females distinguishes the new species from all others of the genus except Neoechinorhynchus chelonos, Neoechinorhynchus lingulatus, and Neoechinorhynchus magnapapillatus, also parasites of turtles. Neoechinorhynchus schmidti n. sp. can be distinguished from these taxa by the structure of the eggs. The eggs of N. schmidti have numerous small, nearly spherical inclusions not found in N. chelonos, N. lingulatus, and N. magnapapillatus.
