Short Description
The new species closely resembles other members of the Etmopterus lucifer group in having longitudinal rows of dermal denticles. It can be distinguished from congeners in having: a broader snout and gill length proportionally longer than other western North Pacific Etmopterus species; a shorter second dorsal fin height and caudal peduncle length; conspicuous dermal denticles on both the second dorsal fin and ventral snout surface; a flank marking, which resembles E. lucifer (Ref. 57876).

Dentition
Diagnosis: Upper teeth in 2–3 series, each tooth with a median lanceolate cusp, flanked by three smaller lateral cusplets on each side; denticles short and robust, arranged in regular longitudinal rows over most of body. Description: Teeth dissimilar in upper and lower jaws; upper teeth multicuspid in 2–3 series, each with a long median cusp flanked by lateral cusplets more than one half the length of median cusp; teeth in lower jaw in single series, unicuspid, interlocking, oblique, bladelike. Teeth in first row of upper jaw 26 (24–26), first row of lower jaw 40 (32–36) [5184];
