REVISION Y CLAVE DE LAS ESPECIES DEL GENERO GLYPTHELMINS

Resumen

The present work is a revision of genus Glypthelmins based on all literature that we could obtain as well as in the study of our mounted specimens. We found a new host and a new locality for G. califoniensis. We have attempted to place in just one key the species, taking the following characters to justify this new arrangement; presence or absence of pharyngeal glands, relation between the oral sucker and the acetabulo, location and size of testis, and size of eggs.
