Glanapteryx is a genus of catfishes native to South America.

Glanapteryx has been proposed as the sister group to a clade composed of Pygidianops and Typhlobelus, with Listrura the sister group to those three.

[1] There are currently two recognized species in this genus:[2] G. anguilla originates from the Negro and Orinoco River basins of Brazil and Venezuela, growing to a length of about 6.1 centimetres (2.4 in) TL.

[4] These species lack an anal fin.

[1] Glanapteryx anguilla has been found in small forest streams with sandy substrate covered by leaf litter.
