Chiasmodontidae (Snaketooth fishes)
Etymology: Pseudoscopelus: Greek, pseudes = false + Greek, skopelos = a lantern fish (Ref. 45335). Lütken did not recognize the presence of photophores on the body, confusing them with pores, but referred to a genus of lanternfish (Scopelus now Myctophum) when he named the genus (Ref. 85782).

ຄີ (ໜາມ)ແຂງຢູ່ຫຼັງປາ (ທັງໝົດ): 7 - 9; ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ): 19-22; ຄີກົ້ນຂອງປາ: 19 - 22; ສັດທີ່ມີກະດູກສັນຫຼັງ: 35 - 36. This species can be distinguished from other members of the Pseudoscopelus scriptus species group by a single character, anal-fin photophores (saf) not extending anterior to the level of anus (vs. extending anteriorly to level of or beyond anus). It is further distinguished from the other species by a set of characteristics: mesial series of premaxillary teeth in 3-4 rows (vs. single row in P. obtusifrons and P. pierbartus); mesial series of teeth in rows of 3-4 teeth gradually increasing of size from lateral to mesial (vs. in rows of 2-3 teeth, with internal row much larger than other teeth in P. cordilluminatus); total vertebrae 35-36, precaudal 18-19 (vs. 31, 14 in P. cephalus);pigmentation in the internal part of mouth exclusive to a dusky area in the skin covering regions with teeth on premaxilla and dentary (vs. internal area of mouth and gill arches black in P. sagamianus ) (Ref. 85782).
A meso- to bathypelagic species found at 250-1,370 m (mean 786 m); juveniles to about 30.0 mm are known from 95 to 590 m (Ref. 85782).
