abstract = {Haematoloechus floedae was originally described from the lungs of Rana catesbeiana in Texas, and later reported in Florida, U.S.A. It was proposed to be synonymous with H. breviplexus, H. parviplexusand H. varioplexus. We obtained specimens of H. floedae from Rana brownorum and R. vaillanti in Yucat?n, Mexico, R. cf. forreri and R. taylori in Guanacaste, Costa Rica, and R. catesbeiana in Georgia and California. Some specimens were processed for morphological study and sequences of the 28S of the rDNA and the mitochondrial COI were obtained from several specimens of each population. Phylogenetic analysis of molecular data indicates studied populations constitute one single taxon, different from H. varioplexus, H. breviplexus and H. parviplexus. Morphological characters that remain constant among populations of H. floedae , and are useful to differentiate this species are oral sucker-pharynx ratio, oral sucker-ventral sucker ratio, ovary and testes shape, extension of uterine longitudinal loops and extension of vitelline follicles (in fully developed worms). Sequence homogeneity among populations of H. floedae suggests a recent spread, maybe due to the introduction of R. catesbeiana for culture to western U.S., south-east Mexico and Costa Rica.}
