Comments.

Takahashi (1950) mentioned that Parathoracaphis kayashimai was closely related to Parathoracaphis setigera , differing in ornamentation of dorsum and leg measurements. The key to Nipponaphidini species on Quercus and the figure of Parathoracaphis kayashimai in Blackman and Eastop (1994) indicate that submarginal setae on abdominal tergite VI of this species are much smaller than setae on other tergites.
