Distribution
South America: Brazil. Pygidianops amphioxus has the broadest reported distribution of any glanapterygine species yet known, spanning over 900 km in straight line. Its westernmost record is the rio Daraá, tributary of the upper rio Negro, and its eastern limit is an affluent to the rio Nhamundá, a northern Amazonian tributary just west of the rio Trombetas. Within the Ducke Preserve, the species occurs in igarapé do Acará and igarapé Tinga (Soares-Carvalho, 2010), which belong to two distinct systems. The igarapé do Acará opens on the rio Tarumã, which is a tributary to the lower rio Negro; while the igarapé Tinga is part of the rio Puraquequara which opens directly into the rio Amazonas. In all cases, P. amphioxus is restricted to lowland terra firme rivers on the northern Amazonian versa
