Diagnosis: D VII + I, 31; A I, 17; P 17; V I, 5; GR 7-8 (mostly rudiments). Body depth is 3.6-3.7 in SL; HL 3.1-

3.4 in SL; eye 4.1-4.4 in HL. Upper jaw broadly rounded posteriorly and vertically reaching below posterior margin of eye; adipose eyelid feebly developed, forming a rim only. Anal fin base distinctly shorter than dorsal fin base; cutaneous keel present on caudal peduncle; caudal peduncle groove present on both upper and lower side. Lateral line slightly elevated over pectoral fin, without scutes. Colour: dorsally bluish grey and ventrally silvery white. Seven dark oblique bands present on upper part of body; spinous dorsal fin dark, soft dorsal and anal fin dusky brown with white tip; caudal, pectoral and pelvic fin yellowish.

Distribution: Indo-West Pacific: Red Sea and East Africa to Japan, Australia and Solomon Island. Southeast Atlantic: southeast coast of South Africa ( Froese & Pauly, 2020). From Indian coast this species was reported from Andaman Islands, Andhra Pradesh, Tamil Nadu, Kerala, Karnataka, Maharashtra ( Joshi et al. 2011), Lakshadweep Islands ( Rajan et al., 2021), Gujarat ( Barman et al., 2000), and Odisha ( Roy et al., 2017).

Remarks: The genus Seriolina Wakiya, 1924 is monotypic, known by single species. The present record forms its first report from West Bengal coast. This species is clearly distinguished from other genera of the family by having elongated maxilla vertically extending to below posterior margin of eye, 4 to 10 numbers of mostly rudimentary gill rakers on first arch, absence of lateral line scutes and anal fin base shorter than dorsal fin base.
