| Description | Phylogenetic analyses based on partial 18S rDNA sequences ofpolyonchoinean monogeneans were conducted to investigate the relationshipsbetween the suborder Dactylogyrinae and related clades as well as therelationships within the suborder Dactylogyrinae, and position monogenean ancyrocephalid species of freshwater fish with European distribution within Dactylogyridae. We investigated the phylogenetic status of the subfamily Ancyrocephalinae within the family Dactylogyridae. We confirmed the monophyly of the order Dactylogyridae and showed thesister groups relationships between the suborders Tetraonchinea and Dactylogyrinea. Our results confirmed the hypothesis based on previousmorphological studies i.e. Tetraonchidae and Sundanonchidae are sister groups within the suborder Tetraonchinea. We did not support the Pseudomurraytrematidae to the family status within the suborder Dactylogyrinea. Phylogenetic relationships within the family Dactylogyridae (following classification of Boeger & Kritsky, 1989) were not concordant with thephylogeny published on morphological characters. Dactylogyridae were formed by two monophyletic clades: first one presents by sister groups the subfamilies Ancyrocephalinae (including freshwater european ancyrocephalids) and the Ancylodiscoinae, second onewas formed by sister groups: Pseudodactylogyrinae and Dactylogyrinae, lastone forms monophyletic clade with Pseudohaliotrema andThylacicleidus, recently has been considered as Ancyrocephalinae, which suggests its paraphyletic features as well as for the subfamily Ancyrocephalinae. We recommend the phylogenetic revision of the genera included recently in the Ancyrocephalinae and their phylogenetic relationships with thesubfamilies Dactylogyrinae and Pseudodactylogyrinae. |
