Integrative taxonomy of n. sp. (Acanthocephala: Isthmosacanthidae) from flatfishes in the Gulf of Mexico.

The Isthmosacanthidae acanthocephalan species of the genus are parasites of marine teleosts and an elasmobranch. In this study, n. sp.

A new species of the genus is described for the southeastern Gulf of Mexico based on morphological and nucleotide evidence. n. sp.

Discovery of a New Genus and Species of Allocreadiidae (Trematoda) in Mexico: n. Gen. n. Sp.

The trematodes of Allocreadiidae are mainly parasites of freshwater fish and the family contains 18 valid genera. Since 2004, 4 genera have been described in the Americas: , , and , of which the latter was recently synonymized with by Franceschini et al., (2021).

Metazoan Parasite Infracommunities of the Tomtate Grunt (Haemulon aurolineatum) as Potential Bioindicators of Environmental Conditions in the Yucatan Continental Shelf, Mexico.

Metazoan parasites and their hosts experience the environmental influence of the seasonal presence of Western and Eastern subzones with different oceanographic conditions on the Yucatan continental shelf (YS). In addition, natural seeps and oil transport in the area lead to the presence of hydrocarbons. We hypothesized that the parasite infrapopulations and infracommunities of Haemulon aurolineatum will respond to environmental variability related with ongoing oceanographic subzone conditions of the YS.

Functional Groups of Metazoan Parasites of the Dusky Flounder (Syacium papillosum) as Bioindicators of Environmental Health of the Yucatan Shelf.

We aimed to compare the percentage of explained variance given by the relationship of species and functional groups of metazoan parasites of the dusky flounder Syacium papillosum and environmental variables from water and sediments in the Yucatan shelf (YS). Parasite data were obtained from 127 S. papillosum specimens collected from 17 of 67 stations.
