(Figs. 28−29)

Psylla abdominalis MEYER-DüR, 1871: 394.

Cacopsylla (Hepatopsylla) abdominalis; BURCKHARDT, 1983: 62. Psylla (Hepatopsylla) seonhyeongae KWON, 1983: 58, syn. nov. Cacopsylla seonhyeongae; PARK, 1996: 272.

Material examined. South Korea: 1 ♀ paratype of Psylla (Hepatopsylla) seonhyeongae, GB, Mt. Juwangsan, 19.vii.1981, Salix sp. (Y. J. Kwon) (NHMB).— South Korea (CB, GW) (NHMB, SNU), Europe (Austria, Germany, Switzerland) (MHNG, NHMB).

Host plant. Salix caprea L., Salix sp. ( Salicaceae), confirmed by the presence of immatures.

Comments. Comparison of material of C. abdominalis from Europe (MHNG, NHMB) and of a paratype of C. seonhyeongae from Korea (NHMB) shows that the two taxa are conspecific. For this reason, they are synonymised here.
