Locality : A type locality was not specified but Zeder worked in Germany and it is probable 
that his specimens were from there. This species has been reported numerous times from many 
localities throughout Western Europe and Britain and as far to the east as Chelyabinsk, USSR 
(see fig. 3). 
Hosts : Rana arvalis, R. dalmatina, R. esculenla, R. graeca, R. macronemis, R. ridibunda, 
H y la arborea, Pelobates fuscus, Alytes obstetricans, Salamandra salamandra (= S. maculosa), S. atra 
(new host record), Triturus alpestris, T. cristatus, T. vulgaris, Bufo bufo, B. regularis, B. viridis, 
Bombina bombina , Natrix natrix, Anguis fragilis, Ophisaurus apodus (new host record). 
Discussion 
Zeder (1800) described a cosmocercoid, Fusaria brevicaudata, from Western European 
amphibians. This species was redescribed by Schneider (1866) and placed in a new 
genus, Oxysoma, with two other species. A type species was not designated. Stiles 
& Hassall (1905) suggested Oxysoma brevicaudata (Zeder) be recognized as type species 
and since it has page priority in Sciineider’s publication, this proposai has been followed 
in later taxonomie studies. Railliet & Henry (1916a) clearly indicated Oxysoma bre¬ 
vicaudata (Zeder) as type species of Oxysomatium and it is évident from this publication
