Monotypic species


The trogons are split into three subfamilies, each reflecting one of these splits, Aplodermatinae is the African subfamily and contains a single genus, Apaloderma; Harpactinae is the Asian subfamily and contains two genera, Harpactes and Apalharpactes. Apalharpactes, consisting of two species in the Java and Sumatra, has only recently been accepted as a separate genus from Harpactes. Harpactes is a genus of birds found in forests in South and Southeast Asia, extending into southernmost China. They are strongly sexually dimorphic, with females generally being duller than males. The two members of the genus Apalharpactes are sometimes included in Harpactes.

This species is considered Near Threatened, as it is likely to be declining moderately rapidly owing to the wholesale clearance of lowland forest habitats throughout its range.
A slow to moderate population decline is suspected to be occurring, owing to the continuing rapid loss of lowland forest habitats across the species’s range. Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect
