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]

gollark: Yes, but if it was a game feature it could be done safely.
gollark: I mean, *arguably* they might be *slightly* terrible ideas with horrible downsides, but you know.
gollark: I came up with the idea of making names a tradeable good like eggs/hatchlings, and wanted to post that along with my earlier one of increasing the length limit and removing character set constraints, in order to encourage more varied discussion.
gollark: I didn't even get to post my great ideas about it.
gollark: Wow, the name exclusivity thread has become surprisingly heated.
