Two new feather mite species collected from the Huet's fulvetta, Alcippe hueti (Passeriformes, Leiothrichidae), in China are described: Proterothrix dinghushani sp. n. (Proctophyllodidae) and Trouessartia pauciseta sp. n. (Trouessartiidae). Males of P. dinghushani have a pair of lateral hysteronotal sclerites and a closed pentagonal sclerotized frame in the postero-median part of propodosoma. Females of this species have the sternum 1/4 of the total length of epimerites, and the terminal cleft exceeds half of the length of the lobar shield. Both sexes of T. pauciseta have a distinctive character, the absence of 3 pairs of hysteronotal setae (d1, d2, and e2), that clearly differs this species from all previously known species of the genus.
