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); aphos: Named for its absence of photophores (a = negative prefix; phos = light, Greek terms).
