Abstract

A specimen (125.5 mm in standard length) of bridled jawfish, Opistognathus nigromarginatus Rüppell, 1830 was collected from the Pulau Bidong, Terengganu, Malaysia using research trawler. Opistognathus nigromarginatus previously has been recorded from Southern Africa to the Persian Gulf, India, Thailand, and Vietnam. We document the first record of this species in Malaysia and the southernmost occurrence in the South China Sea and Western Pacific Ocean. Detailed morphometric and meristic data are presented along with brief diagnostic characters.
