Examination of selected records of intestinal cestodes from native cyprinids provided evidence of the parasite in Nebraska and possibly in the upper Colorado River basin.

Evidence is building for an old pre-European presence in North America, involving the Beringian land bridge and later involvement of susceptible hosts (northern European immigrants), and the etiology of the disease may be changing.
Molecular prospecting for cryptic species in Phyllodistomum lacustri (Platyhelminthes, Gorgoderidae)
Molecular prospecting for cryptic species in Phyllodistomum lacustri (Platyhelminthes, Gorgoderidae) is reported for the first time in the journal Zoologica Scripta.
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.
Richness and diversity of helminth communities in tropical freshwater fishes: empirical evidence
A phylogenetic framework for hosts and parasites will reveal if increased host species richness within host clades, when host speciation is accompanied by habitat or diet specialization, or both, leads to lower helminth diversity in host species by fragmentation of a core helminths fauna characteristic or specific of the larger host clade.

It is hypothesized that host-switching and relationships with the nearctic fauna have been fundamental in determining the helminth fauna of the endemic fish hosts.
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.
Parasite Inventories and DNA-based Taxonomy: Lessons from Helminths of Freshwater Fishes in a Megadiverse Country
It is suggested that future survey work aimed at enhancing the biodiversity inventory should be strategic, i.e., it should combine the need to target missing components of the host spectrum with the choice of appropriate drainages based on biogeographic, faunistic, and hydrologic data.
The historical biogeography of sturgeons (Osteichthyes: Acipenseridae): a synthesis of phylogenetics, palaeontology and palaeogeography
It appears that although acipenserids are a geologically old group, the historical biogeography of surviving lineages is best explained by more recent geological and climatic changes.
