  abstract = {{T}hough for a long time it was hypothesized that the extraordinary diversity of phytophagous insects was better explained by a synchronous pattern of co-diversification with plants, the results of recent studies have led to question this theory, suggesting that the diversification of insects occurred well after that of their hosts. {I}n this study we address this issue by investigating the timing of diversification of a highly specialized group of seed beetles, which mostly feeds on legume plants from the tribe {I}ndigofereae. {T}o that purpose, a total of 130 specimens were sequenced for six genes and analyzed under a {B}ayesian phylogenetic framework. {B}ased on the resulting trees we performed several analyses that allowed a better definition of the group boundaries and to investigate the status of several taxa through the use of molecular species delimitation analyses in combination with morphological evidences. {I}n addition the evolution of host plant use was reconstructed and different molecular-dating approaches were carried out in order to assess the ages of several clades of interest. {T}he resulting framework suggests a more ancient than previously thought origin for seed beetles, and a pattern of rapid host plant colonization. {T}hese findings call for further similar studies in other highly specialized groups of phytophagous insects.},
