Included species
There are currently seven recognized species in this genus:[3]
- Ichthyococcus australis Mukhacheva, 1980 (Southern lightfish)
- Ichthyococcus elongatus S. Imai, 1941 (Slim lightfish)
- Ichthyococcus intermedius Mukhacheva, 1980 (Intermediate lightfish)
- Ichthyococcus irregularis Rechnitzer & J. E. Böhlke, 1958 (Bulldog lightfish)
- Ichthyococcus ovatus (Cocco, 1838) (Lightfish)
- Ichthyococcus parini Mukhacheva, 1980
- Ichthyococcus polli Blache, 1963
Members of this family were formerly placed in the family Phosichthyidae, but a 2025 phylogenetic study found the latter family to be paraphyletic as previously described. Ichthyococcus was found to belong to a distinct lineage sister to the clade containing the Phosichthyidae and Stomiidae, and was thus described as its own family, the Ichthyococcidae.[4]
