Comparison of molecular phylogeny and morphological systematics in fish parasite genus Gyrodactylus Nordmann, Monogenea, Gyrodactylidae Zoologica Poloniae. Overview of fish immune system and infectious diseases. The new species clusters with G. It has been already reported that the two Antarctic gyrodactylids, G.

The present study, however, provides an additional set of measurements taken from the type material of G. The holotype was cut in two, the haptor was mounted on a slide, and the remainder was used for DNA analysis. Confidence limits on phylogenies: This represents the first species of Gyrodactylus to be described from Aphanius and, to date, has the longest ITS1 bp sequenced from any Gyrodactylus.

Remarks on the systematic relationships of the new taxon Subgeneric position. Materials and methods Fish were collected from rocky pools during low tides in July, Only predominantly marine lineages of gyrodactylid species were included. Gyrodactylus species Recorded host species Host family References G.

Gyrodactylidae from Poecilia caucana Steindachner in Venezuela. Morphological and molecular taxonomy of a new species of Fundulotrema and comments on Gyrodactylus stephanus Monogenea: Molecular phylogenetic analysis of the genus Gyrodactylus Platyhelminthes: Light and scanning electron microscopical SEM examination of the opisthaptoral armature and their comparison with all other recorded species suggested morphological similarities to Gyrodactylus rugiensoides Huyse et Volckaert, from Pomatoschistus minutus Pallas.
