Material examined. South Korea (GB, GW, JN, GN, JB) (NHMB, NIBR, SNU).

Host plant. Acer pictum Thunb. var. mono Maxim., A. pseudosieboldianum (Pax) Kom. (Sapindaceae), confirmed by the presence of immatures.

Comments. Psylla albopontis, originally described from Japan, is closely related to Cacopsylla abieti (Kuwayama, 1908) with which it was synonymised by Miyatake (1964a). It differs from C. abieti in the forewing which has dark patches along the apical and posterior margins rather than completely yellow to brown, the denser setae on the inner face of the paramere and the more rounded, rather angular apical dilatation of the distal segment of the aedeagus. We consider P. albopontis a good species of Cacopsylla, remove it from synonymy and transfer it to Cacopsylla . Psylla danpunga Park & Lee, 1982, and Psylla moni Konovalova & Loginova, 1985 display the same diagnostic characters as C. albopontis suggesting they are conspecific. We, therefore, synonymise them with Cacopsylla albopontis . We have not examined material of P. abieti sensu Kwon (1983) . Judging from the description it is a mix of C. albopontis and C. pseudosieboldiani (Konovalova & Loginova, 1985) . The species is associated with several Acer spp. ( Sapindaceae).
