Pseudophacopteron Enderlein 1921, p 116 View in CoL ; Brown and Hodkinson 1988, p 168. Type species: Pauropsylla tuberculata Crawford, 1912 , by original designation.

Chineura Tuthill 1964, p 358 . Type species: Chineura latipennis Tuthill, 1964 View in CoL , by original designation. Synonymized by Yang and Li 1983, p 128.

Brown and Hodkinson (1988) provided a detailed generic description for adult Pseudophacopteron View in CoL . The last instar larvae are described for some species (e.g. Capener 1973; Yang and Tsay 1980; Burckhardt and Brown 1992) but there exists no generic description to date. Because of a considerable morphological variety in some characters, e.g. the form of the circumanal ring and the antenna segmentation, the key to genera of larval Phacopteronidae View in CoL by White and Hodkinson (1985) does not apply to all known Pseudophacopteron spp.
