Hypleurochilus brasil is a species of combtooth blenny from the subfamily Salarinae of the family Blenniidae.

It is endemic to the reefs around Trindade and Martin Vaz off Brazil in the western South Atlantic Ocean.

[2] It is a small species which grows to a maximum recorded standard length of 3.1 centimetres (1.2 in).

[1] Hypleurochilus brasil occurs only off the Brazilian archipelago of Trindade and Martin Vaz in the South Atlantic Ocean, some 1,160 kilometres (720 miles) from the mainland.

[2] The specific name brasil is the Portuguese spelling of Brazil, the country's name being derived from the red coloured wood of the tree Caesalpinia echinate and so the name refers both to the country of its origin and to the red spots along this fish's body.
