Asian barbet

The Asian barbets are a family of bird species, the Megalaimidae, comprising two genera with 30 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. In the past the species were placed in three genera, Caloramphus, Megalaima and Psilopogon,[1] but studies show that Psilopogon to be nested within the clade of Megalaima. Since members of this clade are better treated under a single genus, they have been moved to the genus Psilopogon which was described and erected earlier than Megalaima and is therefore chosen on the basis of taxonomic priority principles. Nearly all members of the family are now in the genus Psilopogon, with the exception of the Caloramphus which is thought to have genetically diverged from the common ancestor around 21.32 million years ago. The latter species is distinct enough to warrant placement in a distinct subfamily Caloramphinae.[2][3] The family name is derived from that of the genus Megalaima which means ‘large throat’, from the Greek mega (μέγας, ‘large, great’) and laimos (λαιμός, ‘throat’).[4]
