Taxonomy & Nomenclature



Conservation Status


Last record: 1974

IUCN status: Critically Endangered (Possibly Extinct)

Though described from Thailand and the Mekong Basin (Cambodia and Lao PDR), records from the latter seem to be erroneous, or misidentifications of B. melanopterus (Ng & Kottelat, 2007; Vidthayanon, 2011), the only other member in the genus, and with which B. ambusticauda was long considered to be conspecific.
