The leaflitter babbler (Pellorneum poliogene) is a species of bird in the ground babbler family Pellorneidae that is found in northern and central Borneo. It was formerly considered to be a subspecies of the short-tailed babbler, now renamed the mourning babbler (Pellorneum malaccense).
Taxonomy
The leaflitter babbler was formally described in 1849 by the English naturalist Hugh Edwin Strickland based on a specimen collected in Borneo. He placed it with the shortwings in the genusBrachypteryx and coined the binomial nameBrachypteryx poliogenis.[1][2] The specific epithet combines the Ancient Greekpolios meaning "grey" and genus meaning "cheek".[3] The leaflitter babbler is now placed in the genus Pellorneum that was introduced in 1832 by the English naturalist William Swainson. It was formerly treated as a subspecies of the short-tailed babbler (renamed the mourning babbler) (Pellorneum malaccense) but based on vocal and genetic differences it is now treated as a separate species and is considered to be monotypic: no subspecies are recognised.[4][5]
