Armbruster, J. W. and M. Hardman. 1999.
Redescription of Pseudorinelepis genibarbis (Loricariidae: Hypostominae) with comments on behavior as it relates to air-holding.
Ichthyological Exploration of Freshwaters 10:53-61.

Abstract:
The loricariid catfish genus Pseudorinelepis is revised. Analysis revealed no difference between the nominal species of Pseudorinelepis and only P. genibarbis is recognized as valid. The Pseudorinelepis from the Rio Branco of Brazil may represent an undescribed species. Pseudorinelepis was examined for its behavior as it relates to the ability of a large esophageal diverticulum to hold air. Pseudorinelepis was shown to breathe air, and, when disturbed, would swim through the water column remaining neutrally buoyant.
