This species is distinguished from its congeners by the following characters: osseous medial groove present; lateral margin of sphenotic notched, narrower medially than anteriorly;
fleshy medial groove of neurocranium, never surpassing posterior margin of eyes; pterotic lateral margin convex, sometimes angled; gill rakers on the first and second gill arches 30-36;
mouth narrow 9.7-12.7% SL; median portion of mesethmoid narrow, medial notch of mesethmoid narrow and deep; external posterior branch of lateral ethmoid columnar and thin;
fenestra delimited by mesethmoid and lateral ethmoid conspicuous (Ref. 116660).
