摘要

Graphical abstractDisplay OmittedHighlights?First molecular phylogeny of Cynolebiini encompassing all genera.?First multigene phylogeny of Cynolebiini resulting in relatively well solved tree.?Cynolebiini genera delimited by morphology are first corroborated by molecular data.?First fossil calibrated analysis supports a Palaeogene origin for aplocheiloids.?Present distribution of Cynolebiini hypothesized to be shaped by Tertiary events.AbstractThe rich biological diversity of South America has motivated a se
