Remarks: Valdivia is a new locality record for Piagetiella caputincisum in Chile, based on a sample from Phalacrocorax gaimardi held in NHML ( Shchedrina et al. 2017). All species of Piagetiella have an unusual feeding behaviour: they develop in the plumage but then migrate and enter the pouch of the host, where they attach firmly, feeding on skin, blood and mucus and, in extreme cases, causing serious damage to the host ( Wobeser et al. 1974).
