Abstract. The sequencing of ITS 1 fragments of the rDNA were assayed in order to discriminate species and to estab­lish relationships between representatives of the genera: Echinoparyphium (E. elegans, E. recurvatum, E. pseu­dorecurvatum), Pseudechinoparyphium (P echinatum), Neoacanthoparyphium (N. echinatoides) and Hypo­deraeum (H. conoideum). The assay has shown that the Key words: Echinoparyphium spp., phylogeny, ITS I, rDNA Introduction The genus Echinoparyphium Dietz, 1909 occupies the… 
Phylogenetic relationships of some species of the family Echinostomatidae Odner, 1910 (Trematoda), inferred from nuclear rDNA sequences and karyological analysis
Results supported close phylogenetic relationships between Echinochasmus Dietz, 1909 and Stephanoprora Odhner, 1902 and showed higher dynamic of karyotype evolution provided by different chromosomal rearrangements including Robertsonian translocations and pericentric inversions than more stable karyotypes of digenean worms parasitizing lymnaeoid pulmonate snails.
Phylogenetic relationships of Echinostoma Rudolphi, 1809 (Digenea: Echinostomatidae) and related genera re-assessed via DNA and morphological analyses
Although the ITS data provided insufficient resolution for an unequivocal solution to the relationships within the genus Echinostoma, it supported the identification of Echinoparyphium ellisi and the distinct species status of three isolates of E chinostoma revolutum as predicted from the ND1 data.
Echinostomes: systematics and life cycles
This chapter provides a review of the most significant literature in the last decade on the systematics and biology of echinostomes and echinOSTome-like digeneans and covers various aspects of the different stages of these organisms.
Deep divergence among subgenera of Gyrodactylus inferred from rDNA ITS region
It is demonstrated that each Gyrodactylus subgenus possesses a unique sequence of the 5.8S gene, and there is concordance between the 6.4S gene and the excretory system used by Malmberg (1970) as a diagnostic character of subgenu status.
An Overview of the Biology of Echinostomes
Larval and adult echinostomes provide good material for biological, physiological, biochemical, immunological and other studies in modern biology, and can be maintained easily and inexpensively in the laboratory.
History of echinostomes (Trematoda)
The history of the echinostomebased studies from the beginnings to the present is examined, divided into four periods according to the types of studies performed in each of them.

Nuclear rDNA ITS sequence variation in the trematode genus Echinostoma: an aid to establishing relationships within the 37-collar-spine group.
DNA sequence data from the nuclear rDNA ITS1, 5.8S and ITS2 of 7 nominal species belonging to the Echinostoma trivolvis and E. paraensei group will assist in the current reclassification of the group and provide a model for future work on sibling species.
Speciation of echinostomes: evidence for the existence of two sympatric sibling species in the complex Echinoparyphium recurvatum (von Linstow 1873) (Digenea: Echinostomatidae).
Two first intermediate host-specific sibling species of the 45 collar-spined echinostome Echinoparyphium recurvatum are presented, found to be morphologically indistinguishable in all major respects, yet they exhibited distinct biological characteristics.
Echinoparyphium speotyto sp. n. (Trematoda: echinostomatidae) from the burrowing owl in Oklahoma, with a discussion of the genus Echinoparyphium.
Echinoparyphium speotyto, a new 41-spined species, is described and represents the first echinostome reported from owls in the United States.
A description of the life stages of Echinoparyphium elegans(Trematoda: Echinostomatidae)
The life cycle of Echinoparyphium elegans Looss 1899 is described from the Free State, South Africa and all stages of the life cycle were described by means of light and scanning electron microscopy.
