Two new genera and species related to Rhytidelasma Gaud, 1966 and Lorilichus Atyeo & Gaud, 1991 are described from the plumage of the red-flanked Lorikeet Charmosyna placentis placentis (Temminck) (Psittacidae). These are Ceratolichus mirabilis n. g., n. sp. and Charmosylichus anamphiestos n. g., n. sp.
