Pseudoscopelus aphos Prokofiev and Kukuev 2006a: 572–727 [type locality: western North Atlantic, 34º N, 50º W, holotype ZMMU 16468, 145.0 mm]; 2008: 46–50, figures 12, 34, 67, 99–101 [species account]. Pseudoscopelus stellatus Beebe 1932: 76–79 [in part, three specimens used in description; western North Atlantic]. Diagnosis. A species of the Pseudoscopelus aphos species group, which can be distinguished from P. parini by the complete absence photophores or clear lines on body (vs. clear lines in place of photophores in ventral part of body in Pseudoscopelus parini, and photophores present in all other species). Description. Medium-sized species of Pseudoscopelus, largest specimen examined 60.7 mm SL. Morphometric data summarized in Table 8. General body shape as described for genus with diagnostic characteristics of species and species group.

Pores in temporal canal 2 (5); supratemporal canal 3 (5); otic canal 2 (5); supraorbital canal 5 (5); supranasal pore 4 (5); epiphyseal branch 3 (5); infraorbital canal 12 (5); preopercular canal 5 (3), 6 (2); mandibular canal 6 (5); fifth pore of mandibular canal 1 (3). Dentition. Enlarged teeth on premaxilla, dentary and palatine. Teeth arrangement as illustrated for Pseudoscopelus scriptus. Premaxilla moderately wide, widest point of premaxillary body 10–14 % in premaxillary length. Premaxillary teeth on head, neck, body and caudal process. Lateral series in single longitudinal row, along lateral edge of premaxillary head, neck, body and caudal process; teeth ...
