Abstract:
The planarian Girardia tigrina sensu lato is the most successful freshwater invasive
triclad. While Antarctica remains a continent without reports for this species, the
single African record is unreliable. Therefore, the species is still unknown on this
continent despite the presence of adequate water masses for its occurrence. Here,
we report the finding of G. tigrina sensu lato in Morocco at Oued Fès, which
constitutes probably its first record in the entire African continent. Despite being
located in only one out of more than 100 localities sampled by us, ongoing
investigations could soon reveal more occurrences of the species in the country and
the rest of the continent.
