Hypoptopoma is a genus of armored catfishes native to South America.
Taxonomy
The genus was established by Albert C. L. G. Günther in 1868 for his new species Hypoptopoma thoracatum, on the basis of the peculiar, depressed, spatulate formation of the head with the eyes on the lateral edges of the head.[1]

There are currently 15 recognized species in this genus:[2]
