Glanapteryx is a genus of catfishes native to South America.
Taxonomy

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]
Species

There are currently two recognized species in this genus:[2]

Glanapteryx anguilla Myers, 1927
Glanapteryx niobium de Pinna, 1998

Distribution and habitat

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.[1]

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