Resumen:
Digenetic trematode larvae identified as Cercaria owreae (Hutton) were recorded in the coela of the following chaetognath species: Flaccisagitta en- flata (Grassi), Serratosagitta serratodentata (Krohn), Ferosagitta hispida (Conant), and Sagitta helenae Ritter-Zahony. The hosts and parasites were collected during 4 oceanographic cruises in February, March, May, and August 1991. The low prevalence of infection (average 0.11 %) was comparable with previous records. The intensity was restricted to 1 parasite. Ferosagitta hispida and Sagitta helenae are recorded for the first time as hosts of Cercaria owreae, and the Mexican Caribbean Sea is reported as a new locality for the geographical distribution of this parasite.
