Six species of chewing lice (Phthiraptera: Menoponidae, Philopteridae)
are reported from four species of seabirds collected off the coast of
Chile. They are Eidmanniella pellucida, Piagetiella transitans, and P
iagetiella caputincisa, from a Guanay cormorant (Phalacrocorax bougain
villii); Harrisoniella ferox collected from a black-browed albatross (
Diomedea melanophrys); Ancistrona vagelli from a white-necked petrel (
Pterodroma externa); and Pelmatocerandra flinti collected from a Magel
lan diving petrel (Pelecanoides magellani). Eidmanniella pellucida and
P. transitans are reported from Chile for the first time. Piagetiella
caputincisa from the Guanay cormorant may be a contaminant from a red
-legged shag (Phalacrocorax gaimardi).
