in the shape of its anterior nostril. This new species differs from the latter in having a more obtuse and shorter snout (profile is 40° vs. ca. 30°, length is less than twice eye diameter vs. equal to or more than twice eye diameter), a longer trunk (40.0% vs. 35.0–36.2% of TL), fewer preopercular pores (3 vs. 4), and in its body coloration in preservative (few spots on head vs. numerous small spots on head and breast).

in the shape of its snout, its preopercular and supratemporal pore counts, and in having 130–145 vertebrae. However, the former can be distinguished from the latter by the shape of its anterior nostril (hole vs. tube), its shorter head (6.3% vs. 7.1–8.3% of TL), and having slightly more vomerine teeth (2 vs. 0–1).
