Phylogenetic analysis of nuclear and mitochondrial DNA reveals a complex of cryptic species in Crassicutis cichlasomae (Digenea: Apocreadiidae), a parasite of Middle-American cichlids.
We obtained nuclear ITS-1 and mitochondrial cox1 sequences from 225 Crassicutis cichlasomae adults collected in 12 species of cichlids from 32 localities to prospect for the presence of crypticExpand
Detecting a Complex of Cryptic Species within Neoechinorhynchus golvani (Acanthocephala: Neoechinorhynchidae) Inferred from ITSs and LSU rDNA Gene Sequences
TLDR
Genetic divergence, in combination with phylogenetic analyses, suggested that the acanthocephalan N. golvani represents a complex of cryptic species, which is composed of at least 3 lineages, and seems to be the result of independent host-switching events from the ancestral population. Expand
Monophyly and systematic position of Glypthelmins (Digenea), based on partial lsrDNA sequences and morphological evidence
TLDR
A phylogenetic analysis using partial lsrDNA sequences to test the monophyly of Glypthelmins, and compares new sequences obtained with those published for different plagiorchiids to clarify the systematic position of GlyPThelmins within the order Plagiorchiida results in identical tree topology.

Integrative taxonomy identifies a new species of Phyllodistomum (Digenea: Gorgoderidae) from the twospot livebearer, Heterandria bimaculata (Teleostei: Poeciliidae), in Central Veracruz, Mexico
TLDR
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. Expand
Description of a New Species of Crassicutis Manter, 1936, Parasite of Cichlasoma beani Jordan (Osteichthyes: Cichlidae) in Mexico, Based on Morphology and Sequences of the ITS1 and 28S Ribosomal RNA
A new species of Crassicutis Manter, 1936 is described from the Sinaloan cichlid Cichlasoma beani (Jordan) (Osteichthyes: Cichlidae) in the upper Río Santiago basin. Crassicutis choudhuryi n. sp.Expand
Morphological and molecular description of eight new species of Gyrodactylus von Nordmann, 1832 (Platyhelminthes: Monogenea) from poeciliid fishes, collected in their natural distribution range in
TLDR
The possibility that gyrodactylid parasites could be introduced along with the fish hosts—this work provides taxonomic information to assess that possibility, as it describes parasites collected from poeciliid fishes within their native distribution range. Expand
A New Species of Auriculostoma (Digenea: Allocreadiidae) in the Mexican Tetra Astyanax mexicanus (Actinopterygii: Characidae) from Central Veracruz, Mexico, Described with the Use of Morphological
TLDR
The new species is set apart from all congeners by the combination of some morphological characters such as the testes position (oblique in most specimens), the ventral to oral sucker ratio (1:1.2 × 1:1), the cirrus sac originating at the ovarian region, and by having vitelline follicles not confluent in the posttesticular region. Expand
Digenean fauna of amphibians from central Mexico: nearctic and neotropical influences.
TLDR
Twenty-two new host and 21 new locality reports are added to the database of amphibian species from central Mexico, finding 21 digenean species; 4 of them are recorded for the first time in Mexico. Expand
Description of two new species of Glypthelmins Stafford, 1905 (Digenea: Macroderoididae) in Rana spp. from Mexico, based on morphology and mtDNA and rDNA sequences
TLDR
The information derived from pairwise distance of independent data-sets plus the phylogenetic information indicate that each of the two isolates from Mexico, identified a priori as G. facioi, represent separate species. Expand
