"New primarily osteological evidence was collected for a reinterpretation of the phylogenetic interrelationships of the teleost fish suborder Stomiatoidei, especially the nominal families Sternoptychidae and Gonostomatidae. Basic differences were found dividing the suborder into two sister groups (proposed as new infraorders), the Gonostomata and the Photichthya. Evidence indicates that the Gonostomata consists of two sister-group families, the Gonostomatidae with six of the 20 genera formerly assigned to this family and the Sternoptychidae including seven genera formerly considered as maurolicin gonostomatids and the three hatchetfish genera, which previously constituted the Sternoptychidae. A hypothesis concerning the phylogenetic interrelationships of the 10 sternoptychid genera is proposed. The genera Thorophos and Araiophos are closely related and proposed as a sister group of the remaining eight genera. The relationships of Maurolicus are unclear, but apparently it forms a sister group of the remaining seven genera. Danaphos and Valenciennellus are closely related and form a sister group of the remaining five genera. Argyripnus and Sonoda form a sister group of the three hatchetfish genera, Polyipnus, Argyropelecus, and Sternoptyx. Argyropelecus and Sternoptyx form a sister group of Polyipnus. Of all the genera, Thorophos is the most primitive, Sternoptyx the most advanced. Evidence was also found demonstrating that the Photichthya consists of two sister groups (proposed as new superfamilies), the Photichthyoidea and the Stomiatoidea. The Photichthyoidea contains one family, the Photichthyidae, including seven of the genera formerly ascribed to the Gonostomatidae. The Stomiatoidea were not investigated in detail at the family or generic level, but it was found that the interrelationships, validity, and contents of the currently accepted families are questionable"--P. 331.
