Description

The Painted Burrowing Frog (also called the Mallee Spadefoot Toad) is a large burrowing frog, 46 to 58 mm in length. Head and body is grey, light brown or yellow with dark brown or olive green patches and a thin, light yellowish vertebral stripe. The underside of the body is smooth and white. The eye is particularly prominent and has a vertical pupil and the tympanum (eardrum) is not visible. Limbs are short. Fingers are cylindrical and unwebbed, whereas the toes are fully webbed, with a black shovel-shaped lump on the undersurface, used for burrowing. Animals are distinguished from the more widespread Common Spadefoot Toad/Sudell’s Frog (N. sudelli) by the lack of baggy skin around the groin, although identification is difficult and is best confirmed by chromosomal analysis. The call is a long and musical trill.

Distribution

This species is widespread in south eastern South Australia and western Victoria but has been found at only two locations in NSW. These are Scotia Sanctuary, adjacent to the South Australian border and in an area to the west of Pooncarie. To date, less than 30 individuals have been found in NSW, though this number is possibly an under-estimation based on the difficulty of identification and also limited access to suitable habitat following rainfall events when the animals are active.

Habitat and ecology

  • Animals can occur in open grassland, mallee, woodland, farmland and cleared areas and are usually found in or around flooded areas after periods of heavy rainfall, including grassy marshes, lagoons, flooded claypans, temporary roadside pools, ditches, mallee swales and farm dams.
  • Animals burrow beneath the soil surface during periods of water shortage and emerge only after heavy rains to breed.
  • They most likely use leaf litter, fallen logs and ground cover vegetation as shelter whilst above ground.
  • Breeding can occur in summer, autumn or winter and males call whilst floating in still water.
  • Diet is not well known but probably consists of a wide variety of invertebrates. Tadpoles are also suspected to feed on large dead insects and plant matter.
