Issue
No recent treatment. It is the common Piabucina in the Gran Sabana highlands of southeastern Venezuela and western Guyana. Ardila Rodríguez (1999) described a new species, Lebiasina provenzanoi from a quebrada tributary to Río Tarotá, Río Aponguao. It is probably a synonym of Piabucina unitaeniata.
