Pseudoscopelus astronesthidens Prokofiev & Kukuev View in CoL species group
Composition. The Pseudoscopelus astronesthidens species group is composed of three species: P. astronesthidens , P. australis , and P. odontoglossum .
Diagnosis. The Pseudoscopelus astronesthidens species group is diagnosed from its congeners by the unique photophore and dentition patterns: luminescent tissue present as discrete photophores (vs. completely absent in P. aphos and as vestigial white lines in P. parini ); mxf short, restricted to area below orbit, not connected to apf posteriorly (vs. mxf absent or if present connected to apf posteriorly); elongate canine teeth present on basihyal and second basibranchial (vs. teeth absent on basihyal; small conical teeth present on second basibranchial); palatine teeth type 4, with considerable ability to bend caudally (vs. palatine teeth of type 1, firmly attached to bone).
Ontogenetic changes. Pseudoscopelus australis has a negative, statistically significant allometric growth of the pectoral fin (P<0.05, Fig. 8 C View FIGURE 8 ); because of limited samples available, it could not be determined if this is also true in P. astronesthidens and P. odontoglossum ( Fig. 21 View FIGURE 21 ). Dentition pattern of specimens was formed in specimens as small as 31.9 mm (CAS-SU 66492).
