Host plant. Pyrus ussuriensis Maxim. ex Rupr. (Rosaceae) ( Park & Lee 1982a).

Comments. The three nominal Pyrus -feeding species Cacopsylla liaoli , C. nigella and C. sandolbaea were recorded from Northeast China, the Russian Far East and Korea, respectively. Their synonymy has been suspected ( Luo et al. 2012; Cho et al. 2017b) and is confirmed here. A critical examination of material from Russia and South Korea showed no significant morphological differences between the nominal species (in the shape of genal processes, forewings shape as well as male and female terminalia). Here, we formally synonymise the three taxa.
