NEW RECORDS OF THREE DEEP-SEA BATHYMODIOLUS MUSSELS (BIVALVIA: MYTILIDA: MYTILIDAE) FROM HYDROTHERMAL VENT AND COLD SEEPS IN TAIWAN

The deep sea mussel genus, Bathymodiolus Kenk & Wilson, 1985, contains 31 species, worldwide. Of which, one endemic species (Bathymodiolus taiwanesis) was reported from Taiwan (MolluscaBase, 2018). Herein, based on the mitochondrial COI results, we present 3 new records of the Bathymodiolus species from Taiwan, namely Bathymodiolus platifrons, Bathymodiolus securforrnis, and Sissano Bathymodiolus sp.1 which were collected from vent or seep environments at depth ranges of 1080-1380 m. Therefore, a total of four species in the genus of Bathymodiolus are now known from Taiwan.
