The genus Sympagus was described by Bates (1881) for Lepturges laetabilis Bates, 1872 from Nicaragua. Tippmann (1960) described Sympagus favorabilis from Peru, and Monné (1985) transferred Nyssodrys buckleyi Bates, 1885 to Sympagus . Hovore & Toledo (2006) revised Sympagus, transferred Stenopsilus bimaculatus Gilmour, 1959 to the genus and described Sympagus cedrelis from Mexico and Sympagus monnei from Panama. Monné & Botero (2015) described Sympagus birai from Panama and provided a key to the species.
