| abstract | The nominotypical subgenus Harpirhynchus Megnin, 1877 (Harpirhynchidae: Acari) is revised. Two other subgenera of this genus, i.e. Neharpyrhynchus Fain, 1972 and Anharpyrhynchus Fain, 1972, are elevated to the genus rank and revised. Four species are recognized in the genus Neharpyrhynchus, i.e. N. plumaris (Fritsch, 1954) nov. comb., N. pilirostris (Berlese & Truessart, 1889) nov. comb., N. trochilinus (Fain, 1972) nov. comb. and N. squamiferus (Fain, 1972) nov. comb. The genus Metharpyrhynchus includes four species, i.e. M. macrophallus Fain, 1972, M. jynx Fain, 1972, M. mossi nov. spec. ex Prinia subjlava graueri, from Rwanda, and M. namibiensis nov. spec., from Philetairus socius from Namibia. A lectotype female is designated for Neharpyrhynchus pilirostris. Three new genera and one new species are described, i.e. Ralliharpirhynchus nov. gen. (type species Metharpyrhynchus porphyrio Fain, 1972), Cypsharpirhynchus nov. gen. (type species Metharpyrhynchus cypsiuri Fain, 1972) and Trichorhynchiella nov. gen. (type species T. paddae nov. spec.) from Padda oryzivora. |
