The distributional range of Ostorhinchus cheni (Hayashi, 1990), previously recorded only from Guam, Taiwan, and Japan, is expanded to include Sri Lanka and the Philippines on the basis of two specimens (104.5–115.4 mm standard length), which are described in detail. The Sri Lankan specimen represents the first record of O. cheni from the Indian Ocean. In addition, the first underwater photograph of a live individual of O. cheni (taken at Tulamben, Bali, Indonesia) is included. The new records suggest that O. cheni is widely distributed in the Indo-West Pacific.
