Glanapteryx is a genus of catfishes native to South America.
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.[1]
There are currently two recognized species in this genus:
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. G. niobium reaches about 5.5 cm (2.2 in). These species lack an anal fin.[1]
Glanapteryx anguilla has been found in small forest streams with sandy substrate covered by leaf litter.[1]
