Pogonopoma Pseudorinelepis Rhinelepis Rhinelepini is a tribe of fishes in the subfamily Hypostominae of the armored suckermouth catfish family Loricariidae.

[3] One of the characters that binds this group together is a large U-shaped diverticulum of the digestive tract; this is always filled with air.

[4] The tribe Rhinelepini has an interesting biogeography and reveal information about the aquatic systems of South America.

Pogonopoma, is found in the Mucuri, Paraíba do Sul, and Uruguay River systems in southeastern Brazil.

It is also thought to have spread through to the Paraíba by a sharing of its headwaters with the Paraná in the past, which eventually got separated into two basins.
