It is endemic to Australia, where it is found in Queensland and the Bunya Mountains.
[1][2][3] This is the "bleating tree frog" that occurs around Brisbane.
[4] It was long confused with the robust bleating tree frog (L. dentata) and was thus only described as a distinct species in 2021.
Rowley et al (2021) distinguished three distinct clades in what was formerly considered a single species (Litoria dentata), based on genetic divergence, slight morphological differences, and notable differences in vocalizations; the latter were collected via the FrogID Australia citizen science project.
The slender bleating tree frog has the shortest call out of the three species, has a more slender build than the other two, a white line extending down its side, and males have a distinctly black vocal sac during breeding season.
