Author: Günther, 1864
Remark: No recent treatment.  It is the common <i>Piabucina</i> in the Gran Sabana highlands of southeastern Venezuela and western Guyana.  Ardila Rodríguez (1999) described a new species, <i>Lebiasina provenzanoi</i> from a quebrada tributary to Río Tarotá, Río Aponguao.  It is probably a synonym of <i>Piabucina unitaeniata</i>.
