Encrasicholina pseudoheteroloba (Hardenberg 1933)


Summary:
A milky white anchovy with a broad silver stripe (almost as wide as the pupil diameter) from just behind the upper margin of the gill cover to the caudal-fin base, a narrow black stripe along the top of the silver stripe, a black occiput, and a silver cheek and gill cover. The species also has a long upper jaw (posterior tip extending beyond the posterior margin of the preopercle), and two unbranched rays in the dorsal and anal fins.
This species was previously considered to be a junior synonym of Encrasicholina heteroloba.
