Males have black, spiny nuptial pads on their thumbs and "accessory spines" on their chests.

Despite once being relatively common, the armoured frog has fallen into rapid decline, and was not seen from 1991 until 2008, when a small population was rediscovered and confirmed to be of this species.

The call for this species is unknown, but is likely to be similar to that of the closely related waterfall frog, (Litoria nannotis).

Tadpoles of this species are undescribed, although they would theoretically look similar to those of L. nannotis–with a large oral disc and a streamlined body, an adaptation to fast-flowing streams.

The reason for decline of these species is not known, but the disease caused by chytrid fungus may be a factor.
