Material examined. South Korea: 1 ♂, 1 ♀ paratypes of Psylla (Hetatopsylla) kwonnabiae, GG, Mt. Myeongseongsan, 16.v.1982 (Y. J. Kwon) (NHMB).— South Korea (GB, GG, GW), Europe (Austria, Czech Republic, France, Germany, Italy, Russia, Switzerland) (MHNG, NHMB, SNU).

Host plant. Salix gracilistyla Miq. (Salicaceae), confirmed by the presence of immatures.

Comments. The comparison of specimens of Cacopsylla pulchra from Europe with paratypes of C. kwonnabiae shows that they are conspecific. For this reason, they are synonymised here.
