coloration of the Quacking Frog. The tympanum is obscure but not hidden unlike the Remote froglet. The length of the adult snout-vent is usually less than 18 mm, which is shorter than the Eastern sign-bearing froglet, and is a pale brown colour or slightly patterned. Additional diagnostic descriptors include: bluntly rounded snout, evenly rounded canthus rostralis, outwardly sloping loreal region, bluntly pointed head (dorsal view), lacks supratympanic fold, elongated tongue, lacks vomerine teeth, toothed upper jaw, vocal sac with slit-like openings on the floor of the mouth. Distal segment of fingers are blunt, not expanded, with roundish sub-articular tubercles (one on 1st and 2nd fingers; two on 3rd and 4th fingers), supernumerary tubercles are present on each palm, two metacarpal tubercles are present, webbing is absent as is the nuptial pad, and subcutaneous glands are present on the base of the 1st finger. Hind limbs are robust with blunt digital segmentation of toes with broad fringes and rounded metatarsal tubercles, supernumerary tubercles are absent indicating the desert froglet does not burrow. Males mature at about 13.0–18.0 cm in length whereas females grow slightly larger to 13.0–18.0 cm. Distribution and habitat Distribution map. Desert froglets are found in arid regions, especially in areas of black soil, extending across the Australian continent from the Kimberley region to the north-west of New South Wales and much of Queensland. The species is often associated with static, temporary or permanent water bodies where it shelters under leaves. They have also been located within artificial habitats such as farm dams, and sheltering under corrugated iron and timber piles. Reproduction Mating call The desert froglet is recognised by the 'melodious chirping' call of the adult male, which sounds similar to a House Sparrow. Each call consists of a repeating pattern: two pulses of 60 milliseconds each and 4000 hertz, which is immediately followed by two additional double pulses of decreasing energy and quickening rate, and a brief pause. Calls are distinct from the shorter creaking call of Sloane's froglet, stretched out call of the Eastern sign-bearing froglet, lower pitch of the Wallum froglet, and grating sounds of the Common eastern froglet. Calling males can be found either hiding under vegetation or exposed at water edges. Life history Spawns of small eggs are laid as submerged clumps either directly within the water or attached to submerged vegetation. Eggs are black at the animal pole and cream at the
