• Bathymodiolus septemdierum Hashimoto & Okutani, 1994
• Bathymodiolus thermophilus Kenk & Wilson, 1985

There also are several fossil species, which are usually only tentatively assigned to hydrothermal vent and hydrocarbon seep-inhabiting mussel genera due to their conservative shell morphology and ongoing taxonomic revision of this group. They include:

• Bathymodiolus (sensu lato) heretaunga Saether, Little, Campbell, Marshall, Collins & Alfaro, 2010
• Bathymodiolus (sensu lato) inouei Amano & Jenkins, 2011
• Bathymodiolus palmarensis Kiel, Campbell & Gaillard, 2010
