This slender Harpadon species features an elongated, slightly compressed body with a smooth and scaleless head. Its deeply forked caudal fin is notably trilobed and has a slightly blackish tint at the tips. The snout is very short and narrow, tapering to a point when viewed from above. The mouth is large, with jaws extending noticeably behind the eye, and is equipped with villiform, backward-curving teeth of varying sizes, each ending in a tiny uncinate tip. The eyes are large, round, and positioned laterally, situated above the front part of the mouth and close to the snout. The body has 40 to 43 lateral line pores, which are faint near the head but become more prominent toward the tail and continue into the central lobe of the caudal fin. There are no axillary processes on the pelvic or pectoral fins. The caudal peduncle is long and slender, with 44 to 45 vertebrae and a neurocranium that is positioned closer to the snout. The dorsal fin originates in the anterior half of the body, measured with the caudal fin, and is located posteriorly above the base of the pelvic fin.
