Among them, Prolistrophorus (Aprolistrophorus) parabidentatus sp. nov. from Akodon azarae from Argentina and Prolistrophorus (Aprolistrophorus) tylomys sp. nov. from Tylomys nudicaudus from Guatemala are described as new for science. New hosts are recorded for the following species: Prolistrophorus (Prolistrophorus) grassii (Radford, 1954) from Zygodontomys brevicauda from Colombia, P. (P.) frontalis (Hirst, 1921) from Oligoryzomys sp. from Argentina, P. (P.) argentinus (Hirst, 1921) from Melanomys calig- inosus, Akodon affinis from Colombia and Scapteromys aquaticus from Argentina, Prolistrophorus (Beprolistrophorus) hirstianus Fain, 1973 from Scapteromys aquaticus from Argentina. Keywords Fur-mites, Listrophoridae, Sigmodontinae, America, systematics, Prolistrophorus Introduction Material and Methods The mite genus Prolistrophorus Fain, 1970 (Acariformes: Mites were obtained from three sources: samples collected by Listrophoridae) currently includes 27 species parasitizing the M. Lareschi from rodents captured in Argentina, samples col- fur of New World mammals. Most of them are associated with lected by M. Barreto from rodents trapped by Dr. V.
