A branchial parasitic bopyrid, Parabopyrella elongata (Shiino, 1949), is newly recorded in Korean fauna. Parabopyrella elongata differs from its congeners by the following characteristics: the head is smooth anteriorly in females; the pleon of females has distinct and wide lateral indentations on both sides; the pleotelson has a rounded distal end in females; oostegite 1 has a rounded posterolateral point; the pleon of males is single-segmented; and the uropod is absent in males. In this study, the detailed description and illustrations of the species are presented with an emended key to known Parabopyrella species in the Far East. The variations in P. elongata were also discussed. This is the first report of the genus Parabopyrella from South Korea.
