The population occurring in Indonesia may not be L. bicolor, and research on call structure or genetics is needed to confirm its taxonomic status.

The iris of the eye is golden, the eardrum is distinct, the vomerine teeth are absent, and there is a strong pectoral fold.

[2] Most abundant in grassland or marshy areas, but also occurs along permanent or semi-permanent streams, billabongs and floodplains.

Breeding starts with summer rains and 10-24 eggs are laid on submerged vegetation in temporary pools.

L. bicolor can be distinguished from L. fallax most readily by the presence of a bronze stripe that runs down the flanks and the call.
