Systematics History

Thought to be related to other green, streaky barbets, with which it forms a clade (4). Previously placed in the genus Megalaima, and the family Capitonidae with the other barbets, until phylogenetic studies resulted in the separation of the Megalaimidae from other barbets (5).

Geographic Variation

No detectable differences between birds from the north and south of range (1).

Subspecies

Monotypic.

Related Species

Closely related to P. flavifrons, which replaces it in Sri Lanka. The two form a clade with other streaked, green barbets, including P. zeylanicus, P. lineatus and P. faiostrictus (4).

Nomenclature

Previously placed in the genus Megalaima as Megalaima viridis, until phylogenetic studies found that Psilopogon was embedded within Megalaima. As this name takes priority, Megalaima is now subsumed within Psilopogon (4).

Fossil History

The only fossil barbet known is Capitonides europeus, an apparent Lybiid barbet from the Miocene of Southern Germany, indicating a broader global distribution of barbets in that epoch (6,7,8).
