New discovery in the USA and phylogenetic position of Salsuginus parasite (Monogenea: Dactylogyridae) associated with the western mosquitofish, Gambusia affinis

Popis výsledku v původním jazyce

he Western mosquitofish, Gambusia affinis (Baird and Girard, 1853), belonging to Poeciliidae, is naturally found across the Mis¬sissippi and Gulf Coast drainages in North America. However, it has been widely introduced globally to control mosquito-borne diseases. Herein, we document the presence of a commonly dis¬tributed dactylogyrid monogenean parasite associated with G. affinis, Salsuginus seculus (Mizelle and Arcadi, 1945) Murith and Beverley-Burton, 1985, found in the North Fork Guadalupe and Brazos River Basins in Texas, USA. Our discovery marks the fourth recorded instance of S. seculus on G. affinis in Texas. The meristic characteristics of S. seculus largely coincide with those observed in previous studies conducted in Texas. However, we observed intraspecific variability when comparing our findings with type-material collected from the Western USA, as well as with specimens of S. seculus found to parasitize non-indigenous G. affinis in Japan. Analysis of 28S rDNA sequences places Salsug¬inus as a sister taxon to a monophyletic group of dactylogyrids (Gussevia, Sciadicleithrum, and Parasciadicleithrum) associated with Neotropical Cichlidae. Our study emphasizes the importance of investigating the potential co-introduction of monogeneans along with G. affinis into new freshwater systems and its impact on native fish populations.
