Etude de quelques trematodes nord-americans (avec note sur la position systematique de Parorchis Nicoll, 1907 suivie d'une revision des generes Galactosomum Looss 1899 et Ochetosoma Braun 1901.
Himasthla rhigedana (Dietz) and Parorchis acanthus (Nicoll) were the first species collected during the cool spring months (March to May), making up about 90% of the cercarial population.
In an experimental mark--recapture study where overall prevalence at the study site was only 30%, Sousa (1993) found that annual replacement of one trematode by another eliminated 72% of Euhaplorchis californiensis (by far the most common trematode in our system), 11% of Acanthoparyphium spinulosum, 8% of Echinoparyphium sp., 8% of Himasthla rhigedana, and 1% of Parorchis acanthus (the most dominant species).
