It is the only frog in the genus "Paracrinia".

Physical Description

This species of frog reaches 30mm in length. This frog varies from light grey brown, pale brown to red-brown above with some darker flecks. The is normally a faint mid-dorsal stripe running down the back. The is a dark band running from the back of the eye to the shoulder. the top half of the iris is silver. The thighs are red in colour, which gives it another name, the red-groined froglet. The ventral surface of this species is light brown with white patches.

Ecology and behaviour

This species is associated with coastal swamps, particularly in wallum swampland and heathland. This species also inhabits dams, ponds and ditches in sclerophyll forest and woodland.

Males make an "annk" call from water or on land during most of the year, but most often after rain in autumn and winter. Eggs are laid in water attached to sticks and leaves. The tadpole of this species has very deeply arched tail fins. Metamorphosis occurs during spring and autumn after a tadpole life span of about 100 days. Metamorph frogs measure 13mm and resemble the adult, however the thigh red colouration is not yet fully developed.
