The Bay of Bengal coast, Bangladesh is a hotspot of fisheries abundance and diversity. A new species of Carangid family Alepes kleinii is recorded and described for the first time in the coastal waters of Bangladesh. A total of 29 individuals of Alepes kleinii were collected from the surveyed areas between January to March, 2016. Validation of this species was confirmed by phenotypic characteristics including body and fins colour, shape, vertical stripes, number of fin rays etc. which were found to be identical to that of the Alepes kleinii described in existing literature. The regression parameter value (b = 2.81) of the length-weight relationship (W = aL b ) indicates that the Bay of Bengal provides favourable environmental conditions for the growth and development of this species. The discovery of the razorbelly scad in these waters provide valuable information regarding species distribution and extension, location and habitat preference. This information is prerequisite for the sound management of the coastal fisheries of Bangladesh.
