Subspecies ''tormenti'', known as the Kimberley flyrobin, was considered a separate species for many years. It is unusual in that it lacks the yellow pigmentation of the other subspecies.

and Walter Boles reclassified it as a subspecies, since hybrids between subspecies ''tormenti'' and ''flavigaster'' have been found in the vicinity of Cambridge Gulf—between the ranges of the two subspecies.
As well as lemon-bellied flyrobin, the species is also commonly known as lemon-breasted flycatcher (from when belly was thought crude), yellow-bellied flycatcher, yellow-breasted flycatcher, or brown-tailed flycatcher (subspecies ''tormenti'').[
]
Description
The adult lemon-bellied flyrobin is around long. The sexes have similar plumage. The nominate subspecies ''flavigaster'' has lemon yellow underparts, a white throat, grey face with a white eyebrow stripe, and olive-brown upperparts. Subspecies ''tormenti'' has white underparts, more greyish upperparts, has a longer bill and tail and is larger overall. Subspecies ''flavissima'' resembles ''flavigaster'' but has a more obvious yellow tinge to the upperparts, throat, yellow eyebrow and a shorter tail, while ''laetissima'' more closely resembles ''flavigaster'', but has a shorter tail and bill and is larger overall.[
]
Distribution and habitat
The species ranges from the Ord River in the west to coastal Queensland, and is found in mangroves, paperbark swamp forests, and woodland.[
]
Feeding
The lemon-bellied flyrobin is an insectivore, hunting its prey in the foliage or dead branches of trees and shrubs and only rarely on the ground.[ Fieldwork in Kakadu National Park found that it occasionally caught large insects over in length; insects were generally caught by the bird hawking or sallying.]
Breeding
Breeding throughout its range, the lemon-bellied flyrobin breeds from August to February, raising one or two broods a season. The nest is a small dish-shaped structure made of bark and grasses in the fork of a tree. A single egg measuring is laid, pale blue with brownish markings.
