title: A new feather mite species of the genus Picalgoides Černý, 1974 (Astigmata: Psoroptoididae) from a passerine host in Costa Rica.
abstract: A new feather mite species, Picalgoides giganteus n. sp. (Psoroptoididae: Pandalurinae), is described from the tawny-throated leaftosser Sclerurus mexicanus Sclater (Passeriformes: Furnariidae) in Costa Rica. Among the 10 species of Picalgoides Černý, 1974, including the new one, this is the third recorded from a passerine host; the remaining seven nominal species are associated with hosts of the order Piciformes. Brief data on the host-parasite associations of Picalgoides spp. are provided. Megninia megalixus Trouessart, 1885 from the short-tailed green magpie Cissa thalassina (Temminck) is transferred to Picalgoides as P. megalixus (Trouessart, 1885) n. comb.
