 Two studies in 2002 and 2007 of mitochondrial cytochrome b sequences generally agreed that "Selaroides" was most closely related to "Selar" (depending on analysis type), however both indicated a closer relationship to the deeper bodied genera such as "Caranx" and "Hemicaranx" than to the scads of "Trachurus" and "Decapterus".The yellowstripe scad is a small species, attaining a maximum length of 22 cm, but is more common at lengths less than 15 cm.The species has a body shape typical of many scads, with a compressed elongate, oblong body with the dorsal and ventral profiles equally curved.
