The genus Rhachotropis has the widest horizontal and bathymetric distribution of all amphipod genera known worldwide. Characteristic species of Rhachotropis were collected at 3200 m depth in the Kuril basin of the Sea of Okhotsk. Morphological investigations revealed a species new to science, which is here described in detail. Juveniles were removed from the marsupium of the holotype; their morphological features were investigated via scanning electron microscopy and compared to the adults. The molecular barcode of the new species, Rhachotropis marinae, was obtained. Comparison with available Rhachotropis COI data revealed clear separation of the new species from all known species as well as from two other Rhachotropis species also collected during the SokhoBio expedition. The three Rhachotropis species from abyssal depths in the Sea of Okhotsk did not group together when their COI region was analysed with Rhachotropis sequences from other parts of the world. The number of described species of Rhachotropis is now increased to 62.
