Abstract: We report the first record of concertina fish, Drepane longimana from the St. Martin’s Island of Bangladesh. The sample specimens were collected from the St. Martin’s Island on 28 November 2015. Morphometric and meristic studies were performed for taxonomic identification. The body was oval and strongly compressed. The mouth was highly protrusible, formimg a down ward pointing tube when protruded. A single dorsal fin present with eight to nine (usually eight) spines (fourth spine largest) and 19 to 23 soft rays and the anal fins consists of three spines and 17 to 19 soft rays. The head and body were silvery in color. The presence of four to nine subvertical dark bars on dorsal part of the body from head to caudal fin base, easily distinguish this species from other closely related species of genus Drepane. The morphometric and meristic data thus confirm the presence of D. longimana in Bangladesh. This report updates the geographical distribution for this species confirming its presence in the coastal region of Bangladesh, and extends the number of marine fish known from the area.
