It is distinguished from the two other species of Wetmorella, W. albofasciata and W. nigropinnata, by having a narrow oblique white bar behind the eye and two parallel, narrow, white bars in the middle of the body that are slightly oblique. Wetmorella albofasciata has two narrow white bars on the body, but they converge as they pass ventrally. Wetmorella nigropinnata has two white bars on the body only as juveniles and subadults, but the bars are broad and slightly oblique in the other direction. Wetmorella tanakai also has a longer head, longer snout, and narrower interorbital space.
