Such is the case of a group of genera, most of them endemic to the Neotropical region (NT), whose monophyly has been repeatedly confirmed and which constitutes the so-called Neotropical lineage (NL). However, basal relationships have not been clarified, neither for Philonthina nor its NL. The NL includes ∼300 species and 26 genera, but two of them (<i>Belonuchus</i> Nordmann and <i>Paederomimus</i> Sharp) account for two-thirds of its species.

We show that Philonthina originated during the Late Cretaceous ∼ 67.6 Ma and diversified into five main lineages mostly during the Eocene.
