Pseudophryne coriacea
Family: Myobatrachidae
Common names: Red Backed Broodfrog; Red-backed Toadlet; Keferstein's Toadlet
Description: This frog is rich brown to bright red on its back with darker flecks. It has a broad black band that runs down the sides of the head and body. The bases of the arms are white. The belly is smooth or slightly granular and marbled black and white. The skin on the back is smooth with low warts. The toes are not webbed.
Size: 35 mm
Habitat: This frog lives in sclerophyll forests and marshy areas, where it hides under logs and leaf litter.
Call: A short, grating "ark" repeated at regular intervals.
Breeding: Males call from spring to autumn while sitting in their nests, which are made in damp soil under leaf litter, grasses and rocks.
Eggs: Are large and laid in burrows, hatching when they are flooded by rain.
Tadpoles: Are small and grey-brown in colour.
Similar species: This frog can be distinguished from Assa darlingtoni by its belly colouration and distinguished from Pseudophryne raveni by its black sides.
Conservation Information
Suspected threatening processes
- Direct human impact/urbanisation/tourism
- Habitat modification (e.g. vegetation clearing, invasive weeds)
Population size: An estimate of the total number of adults present in the species entire range is >50000 individuals. Some factors affecting population size and distribution are known, but 1 or more major factors are unknown.
Population trend in Australia over the past 50 years: Population trend unknown; no information on habitat changes.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Not known to concentrate or exist in discrete locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: None directed primarily at the taxon.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 51-200 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is 2-3 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 80,001-1,000,000 km² (up to 12% area of Australia or about the area of South Australia).
Distribution trend: Area occupied has declined by < 25%. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Broad range limits or habitat associations are known, but local occurrence cannot be predicted accurately.
