| Popis: | Pseudoacanthocephalus goodmanin. sp. is described from faecal pellets collected fromSclerophrys gutturalis(Power, 1927), the guttural toad. The species is characterized by a suite of characters, including a proboscis armature of 14–18 longitudinal rows of 4–6 hooks with simple roots, lemnisci longer than the proboscis receptacle, equatorial testes, a cluster of elongated cement glands and eggs without polar prolongations of the middle membrane 72.6–85.8 long. The toad had been accidentally translocated from Mauritius to the UK in a tourist's luggage and survived a washing machine cycle. The guttural toad was introduced into Mauritius from South Africa in 1922 and the cane toad,Rhinella marina(Linneaus, 1758), from South America, between 1936 and 1938. It seems most likely, therefore, thatP. goodmaniwas introduced, with the guttural toad, from South Africa. The cane toad is host to the similar species,Pseudoacanthocephalus lutzi, from the Americas, butP. lutzihas not been recorded from places where the cane toad has been introduced elsewhere. Clearly, the guttural toad is a hardy and adaptable species, although it seems unlikely that it could become established in Northern Europe. Nevertheless, any accidental translocation of hosts poses the potential risk of introducing unwanted pathogens into the environment and should be guarded against. |
