Herein, we recorded Omobranchus zebra and O. smithi for the first time from West Bengal, India based on six individuals of O. zebra (33.66-53.37 mm SL) and five individuals of O. smithi (35.76-49.82 mm SL) collected from the brackish waters of the mangrove islands in the Indian Sundarbans. Omobranchus zebra is characterized by having XII, 18-20 dorsal fin rays, II, 20-22 anal fin rays, and a conspicuous colour pattern on the head and body. Omobranchus smithi is distinguished by having XII, 18-19 dorsal fin rays, II, 21 anal fin rays, a conspicuous dark spot on the anterior portion of the dorsal fin membrane, a crescentic mark posterior to the dorsal part of the orbit along with a slender crest on the head of males.
