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); astronesthidens: Named for the characteristic shape of the marginal premaxillary teeth, resembling the dentition in the stomiiform genus Astronesthes.

Short description
সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স
পৃষ্ঠীয় কাঁটা (মোট ) : 7 - 8; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 23 - 28; পায়ূর নরম পাখনা্তুন্ড: 23 - 28; কশেরুকা : 36 - 37. This species is characterized by the following: dark orobranchial cavity; inclined teeth in the marginal row on the premaxillary are increased in size in the postorbital portion of the bone; teeth on the tongue; minute or no gill rakers on first gill arch; maxillary (suborbital) photophores usually well developed, disconnected with anteropreopercular photophores; well developed posteropreopercular photophores; no transverse ventral (interventral) photophores; thin cranial roofing bones; upper jaw long, 66.7-76.2% head length (HL), usually more than 69% HL (80% of specimens; mean 70.3%); moderately long pectorals, 16.0-22.5% SL, usually more than 17% SL (95% of specimens; mean 19.1%); group of three pores above the second nare; 36-37 vertebrae (Ref. 78617).
The depth range is a mix of Ref. 57779, 78617 and 126430.
