This genus has been separated from Ptilinopus proper, because its members 
have the pectoral feathers normal and not bifurcated. The tail is generally 
rather long, and the under tail-coverts not quite so long as in Ptilinopus. Other- 
wise there are no differences of generic value, and one might just as well unite 
Leucotreron with Ptilinopus. 
Distribution. Indo-Malayan and Western Austro-Malayan Archipelago.
