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. First dorsal-fin rays vii (1), viii (2), ix (2); second dorsal-fin rays xxiii (1), xxiv (1), xxvii (1), ii+21 (2); anal-fin rays iii+20 (2), iii+21 (2), iii+23 (1); pectoral-fin rays 12 (1), 14 (1), 15 (1); pelvic-fin rays I+5 (5); caudal-fin rays i+7+8+i (4), i+8+7+i (1). Branchiostegal rays 7 (5). Pre-caudal vertebrae 18 (2); total vertebrae 36 (2). Lateral line complete; lateral-line pores 74 (1), 75 (1), 76 (1), 77 (2). 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 ...
