Paracrinia haswelli
Family: Myobatrachidae
Common names: Haswell's Froglet; Red-groined Froglet
Description: This frog is light grey to brown on its back with irregular darker flecks. There is a black stripe that runs from the nostril, through the eye and down the side. Some individuals also have a pale stripe running down the spine. The belly is granular and light brown with pale flecks. There are red patches on the backs of the thighs, the groin and at the base of each arm. The skin on the back is smooth with small tubercles (lumps) and the toes are not webbed.
Size: 35 mm
Habitat: This frog lives in wet and dry sclerophyll forests and healthlands. It is usually found near creeks, swamps and dams.
Call: A short "ank" repeated slowly.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Males call from under vegetation on the banks or while floating in the water. Males call from August to March.
Eggs: Are laid in loose clusters and attached to plant stems below the water's surface.
Tadpoles: Can vary in colour from transparent yellow to yellow-brown or grey. They usually remain hidden amongst water plants in warm shallow water.
Similar species: This frog can be distinguished from species of Crinia, Uperoleia and Pseudophryne by its smooth light brown belly and red groin patch.
Conservation Information
Suspected threatening processes
- Direct human impact/urbanisation/tourism
- Inappropriate catchment management, including degraded water quality
- Exotic predators (e.g. trout, Gambusia)
- 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. Factors affecting population size and distribution are unknown or unsubstantiated.
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 201-1000 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is <2 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 1001-80000 km² (up to 1% area of Australia or about the area of Tasmania).
Distribution trend: Decline, if any, unknown. (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.
