Glanapteryx is a genus of catfishes (order Siluriformes) of the family Trichomycteridae. It includes two species, G. anguilla and G. niobium.^[1]

Glanapteryx is a monophyletic genus. Glanapteryx has been proposed as the sister group to a clade composed of Pygidianops and Typhlobelus, with Listrura the sister group to those three.^[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.^[3] G. niobium reaches about 5.5 cm (2.2 in).^[4] These species lack an anal fin.^[2]

Glanapteryx anguilla has been found in small forest streams with sandy substrate covered by leaf litter.^[2]
