See text Hollardiinae is a subfamily of marine ray-finned fishes belonging to the family Triacanthodidae, the spikefishes.

Hollardiinae was first proposed as a subfamily of the family Triacanthodidae in 1968 by the American ichthyologist James C.

[3] Hollardiinae contains the following genera and species:[4][5][6] Hollardiinae spikefishes are distinguished from theose in the nominate subfamily by the possession of a dome like supraoccipital and by the first branchiostegal ray being slightly enlarged at its tip but the tip not being turned inwards.

[4] The dome like supraocciptal stops the epiotic bones from meeting on the upper surface of the skull, they also have a pelvis which resemvles a shaft and sits behind the spines of the pelvic fins.

[6] Hollardiinae spikefishes appear to have their origins in the prehistoric Tethys Sea at some time between the Palaeocene and the Oligocene, and from there they migrated west across the Atlantic Ocean.
