Diagnosis

Description: Eye is relatively large, its lower edge well above a line from the tip of the snout to the middle of the caudal fin fork. Caudal fin is moderately forked and with blunt tips. Overall color is silvery white to grayish. The scales of the back and sides have a small brownish basal spot. Prominent black blotches are scattered mainly on the anterior half of the body. A very faint bar is sometimes present below the eye to the lower edge of the cheek. Fins are clear to reddish, the caudal fin sometimes dusky reddish-brown. Faint spots may be evident on the dorsal, caudal, and anal fins (Ref. 2295). Body depth 2.4-2.5 in SL (Ref. 90102).
