The Red-backed Toadlet (Pseudophryne coriacea) is a species of ground frog native to the coast and adjacent ranges of eastern Australia, from just north of Sydney to South-eastern Queensland.
Physical Description
This species of frog reaches about 35m in length. It is normally red, from red-orange or red-brown on the dorsal surface, however on occasion grey-red colour morphs can occur (see image). There is a dark (normally black) "dividing" line present right down the entire side of the frog, starting from the nostril. This line separates the red dorsal suface from the strongly marbled black and white ventral surface. There is a white spot in the armpits.
Ecology & Behaviour
This species is normally associated with rainforest and wet sclerphyll forest, however is also found in dry sclerophyll forest, woodland and at times cleared areas. It is normally found in areas that are frequently inundated mostly roadside ditches, creeks and temporary pools.
Males make an "ark" call, similar to most Pseudophryne species, however slight more of an elongated note compared to P. australis and P. bibronii. Males call from under moist leaf litter and rotting logs, during spring, summer and autumn, they breed after rain. As with other Pseudophryne species the male stays with the eggs in the nest site and may mate with more than one female. Eggs are laid in the nest site and tadpoles hatch after heavy rain floods the nest site and the develop in the temporary pools. Tadpole development is relatively short, due to the ephemeral nature of the pools in which they dwell.
