Aguarunichthys is a genus of long-whiskered catfishes native to South America.

There are currently three recognized species in this genus:[1] Aguarunichthys is derived from Aguaruna, the name of a society of people from where A. torosus was collected, as well as ichthys, meaning fish.

The species name of A. torosus is derived from the Latin brawny or muscular for its body form.

[3] These fish species are rarely captured and are unknown to the local fishermen; this may be due to their deep-bottom dwelling habits.

[3] Aguarunichthys was originally described due to the distinctive finger-like projections of the gas bladder.
