A large-type sexannulate leech species, Orobdella ibukifukuyamai sp. nov., from Kii-Oshima Island, Japan, is described based on morphologic and molecular data. Phylogenetic analyses using nuclear 18S rRNA, 28S rRNA, histone H3, mitochondrial cytochrome c oxidase subunit I, tRNACys, tRNAMet, 12S rRNA, tRNAVal, 16S rRNA, tRNALeu and NADH dehydrogenase subunit 1 markers showed that O. ibukifukuyamai formed a clade with the sexannulate O. okanoi Nakano, 2016 and O. yamaneae Nakano, 2016 and octannulate O. nakahamai Nakano, 2016, which are endemic to Shikoku island, Japan.
