Both sexes of Scottolana geei n. sp. (Copepoda: Harpacticoida: Canuellidae) are described from the Bohai Sea, China. The species belongs to the longipes-group of Scottolana which includes S. longipes, S. longipes sensu Por (1964), S. longipes sensu Wells (1967), S. longipes sensu Wells and Rao (1987), S. uxoris and S. dissimilis. This lineage can be differentiated from other congeners by the presence of only two postgenital somites in the female and three in the male, the modified P4, the sexual dimorphism of the P3 endopod and caudal rami, the presence of a spinous process on the bases of P2–P4, and the characteristic caudal ramus with hook-like extension along the inner margin and spinular patch near the distal outer corner. S. geei is unique among the Harpacticoida in displaying a nine-segmented antennary exopod. It is most closely related to S. longipes sensu Wells and Rao (1987) from the Andaman Islands. Scottolana bulbifera (Chislenko, 1971) is redescribed in detail on the basis of Bohai Sea material and discrepancies with Chislenko's original description, based on specimens from the Sea of Japan, are re-evaluated.
