Analysis of the nearly complete 18S rRNA genes of nine species from the three classes of Acanthocephala and four species ofRotifera found statistically significant support for the monophyly of Rotifera, represented in the analysis byspecies from the clade Eurotatoria, which includes the classes Bdelloidea and Monogononta.
Phylogenetic analysis based on 18S ribosomal RNA gene sequences supports the existence of class polyacanthocephala (acanthocephala).
STATUS OF CORYNOSOMA (ACANTHOCEPHALA: POLYMORPHIDAE) BASED ON ANATOMICAL, ECOLOGICAL, AND PHYLOGENETIC EVIDENCE, WITH THE ERECTION OF PSEUDOCORYNOSOMA N. GEN
The possession of genital spines has been considered as a key taxonomic trait to differentiate Corynosoma from other genera of the Polymorphidae. However, Corynosoma currently consists of 2 groups of…
Trematode diversity in freshwater fishes of the Globe II: ‘New World’
A better understanding of trematode diversity and biology will also depend on strategic sampling throughout the Americas, as well as the paucity of known life-cycles.

Maximum parsimony and likelihood analyses indicated that species of Corynosoma that inhabit hosts in the marine environment form a monophyletic assemblage, but yielded conflicting hypotheses for the relationship of Corynsoma cetaceum to other members of the genus.
Biogeography of helminth parasites of freshwater fishes in Mexico: the search for patterns and processes
Three predictions about host‐specificity, faunal exchange in transitional areas, and the biogeographical ‘core’ fauna are evaluated, all of which follow from a fundamental hypothesis: that parasites show characteristic associations with particular host clades.
Filling the gaps in the classification of the Digenea Carus, 1863: systematic position of the Proterodiplostomidae Dubois, 1936 within the superfamily Diplostomoidea Poirier, 1886, inferred from…

The phylogenetic position of the family Proterodiplostomidae Dubois, 1936 was tested based on partial 28S r DNA and complete 18S rDNA sequences for Crocodilicola pseudostoma, a crocodile parasite that has been found as a progenetic metacercaria parasitising the pale catfish Rhamdia guatemalensis in Mexico and in other siluruforms in the Neotropics.
Phylogenetic relationship among genera of Polymorphidae (Acanthocephala), inferred from nuclear and mitochondrial gene sequences.

Mapping the second intermediate hosts (fish) onto the species tree suggests that metacercariae of these five species exhibit some level of host specificity towards their fish intermediate host (at the family level), irrespective of geographical distribution.
Integrative taxonomy identifies a new species of Phyllodistomum (Digenea: Gorgoderidae) from the twospot livebearer, Heterandria bimaculata (Teleostei: Poeciliidae), in Central Veracruz, Mexico

Comparison of about 1,500–2,200 nucleotides of cox1 and 28S rDNA and ITS1 strongly supports the status of P. inecoli as a new species and Bayesian inference analysis of combined datasets of 28SRDNA and coX1 sequences showed that P.Inecoli n.
