Taxonomy
The fourspine sculpin was first formally described in 1904 by the American ichthyologists David Starr Jordan and Edwin Chapin Starks with its type locality given as Niigata in Japan.[4] This species is placed in the monospecific genus Rheopresbe by some authorities, as molecular analyses indicated that this species was a sister taxon to Trachidermus fasciatus, another catadromous Japanese sculpin.[5] This taxonomy is followed by Eschmeyer's Catalog of Fishes.[2] The specific name kazika is a Japanese word for river sculpins.[6]
