Distribution. Japan (Hokkaido Island: Rumoi Sub-prefecture).

Remarks. The species was originally described in Syntelopodeuma from Hokkaido Island (Rumoi), Japan (Verhoeff 1939), and later transferred to the genus Diplomaragna (Shear 1990) . Mikhaljova (2000) put it in her newly erected genus Maritimosoma Mikhaljova, 2000 . However, taking into account the structure of gonopods of this species (especially the lack of posterior gonopod mesal processes, the presence of which is one of the main distinguishing characters of species of Maritimosoma), morphological similarities with other Hokkaido species of Diplopmaragna and the geographical evidence, here we refer to it again as belonging to Diplopmaragna.
