HaplorchoidesChen, 1949 (Haplorchinae: Heterophyidae) in freshwater fishes

Abstract

AbstractTwo metacercariae ofHaplorchoides, recorded in the fingerlings of over a dozen species of freshwater fishes, are described and illustrated. Oyigerous flukes were recovered from older specimens of two species of fishes procured from the same locality. Comparison of taxonomic characters of the juveniles and adults suggests that they are conspecific. The metacercariae and adults are assigned to two new species,Haplorchoides pearsoniandH. mehrai. The observations, presented herein, necessitated a review of the species named under this genus and a revision of the generic diagnosis. The reports on fish intermediaries ofH. attenuatushave been enlarged.
