Resumen:
Species of the allocreadiid genusCreptotremaare parasites of freshwater
fishes in the Americas. Species in the genus possess one pair of
muscular oral lobes on the oral sucker. Currently, the genus contains
eight species, six distributed in South America, one in Middle America
and one in North America. Genetic data are only available for the North
American species,Creptotrema funduli, a parasite of fundulids originally
described from Oneida Lake, New York State. In this study, we obtained
28S ribosomal DNA sequences of trematodes morphologically similar
toCreptotrema agonostomifrom the mountain mullet,Dajaus monticola,
across a wide geographical range in Middle America. Our molecular
phylogenetic analyses showed that (1) the genusCreptotrema, as currently
conceived, is not monophyletic; (2) the allocreadiids in mountain
mullets should be re-allocated in the genusPseudoparacreptotrema; and
(3) the allocreadiid trematodes fromD. monticolaacross Middle America
represent four morphologically similar species, three of which can be
distinguished genetically. These three new species are described herein
using an integrative taxonomy approach. We contend that accurate
estimates of species diversity and phylogenetic relationships among
allocreadiids, and most likely other species of trematodes, necessarily
require an integrative taxonomy approach that should consider at least
DNA sequences and scanning electron microscopy.
