A new species of the genus gergithoides schumacher (Hemiptera: Fulgoroidea: Issidae) from Korea

This paper is written to provide a new species, Gergithoides jejudoensis sp. nov., that was previously misidentified as Gergithoides carinatifrons Schumacher, 1915 from Korea. The new species is similar to G. carinatifrons and G. gibbosus, Chou & Wang but can be easily distinguished from the latter by the structure of lateral sclerotized processes of aedeagus, apical process of genital styles, and other characters. The new species is described and illustrated, and a revised key to the known species of the genus is presented.
