Species of the codlet fish family Bregmacerotidae of Taiwan are reviewed. A single genus, Bregmaceros, with 4 species are recognized: B. japonicus Tanaka, 1908, B. lanceolatus Shen, 1960, B. pescadorus Shen, 1960, B. pseudolancelatus Torii, Javonillo and Ozawa, 2004. The previous record of B. mcclellandi Thompson, 1840 is proved to be a misidentification of B. pseodulanceolatus and should be excluded from the list of fauna in Taiwan. A key to all 4 species of Taiwan is provided.
