Pseudoscopelus Luetken
[[Pseudoscopelus Lütken]] Four genera are currently recognized in Chiasmodontidae, one of the few families of bathy- and mesopelagic fishes in the large actinopterygian order Perciformes (Nelson, 2006): Chiasmodon Johnson (1864); Pseudoscopelus Lütken (1892); Dysalotus MacGilchrist (1905); and Kali...
