Resumen:
Adult specimens of monorchiids (Digenea) were collected from the
intestines of the white grunt, Haemulon plumierii Lacepede (Haemulidae),
and the white mullet, Mugil curema Valenciennes (Mugilidae) from five
localities off the Yucatan Peninsula and one locality in the Gulf of
Mexico. Some specimens were photographed and sequenced for two molecular
markers, the large subunit (LSU) of nuclear rDNA and the cytochrome c
oxidase subunit 1 (cox1) of mitochondrial DNA. Other specimens were
processed for morphological analyses. Newly generated sequences were
aligned with other sequences available in GenBank. Bayesian inference
and maximum likelihood analyses were implemented using the data sets of
LSU and cox1 independently. Reciprocal monophyly evidenced through
phylogenetic analyses, sequence divergence values for both molecular
markers, and detailed morphological analyses, including scanning
electron microscopy photomicrographs, revealed three new genetic
lineages, i.e., species, as parasites of M. curema. The three new
species are Sinistroporomonorchis mexicanus n. sp.,
Sinistroporomonorchis yucatanensis n. sp., and Sinistroporomonorchis
minutus n. sp. Two additional species of monorchiids were sampled,
characterised molecularly, and re-described, namely
Sinistroporomonorchis glebulentus (Overstreet, 1971) from the white
mullet, and Alloinfundiburictus haemuli (Overstreet, 1969), from the
white grunt.
