PsilopogonCaloramphus Megalaimidae, the Asian barbets, are a family of birds, comprising two genera with 35 species native to the forests of the Indomalayan realm from Tibet to Indonesia.

They were once clubbed with all barbets in the family Capitonidae but the Old World species have been found to be distinctive and are considered, along with the Lybiidae and Ramphastidae, as sister groups.

Nearly all members of the family are now in the genus Psilopogon, with the exception of those in Caloramphus, which are thought to have genetically diverged from the common ancestor around 21.32 million years ago.

[4] The phylogenetic relationship between the Asian barbets and the eight other families in the order Piciformes is shown in the cladogram below.
