Wallum Sedge Frog

Litoria olongburensis is found across 12 electorates.

The Wallum Sedge Frog is a small tree-frog that makes a soft 'buzzing' call. The snout-to-vent length of adult males is approximately 25 mm, while the SVL of adult females is 27–31 mm. The tip of the snout is pointed and protrudes beyond the lower jaw. The canthus rostralis is sharp and angular in cross section and the loreal region is flat and vertical. The dorsal colouration is grey-brown, beige or bright green, occasionally with dark flecking. Skin is smooth or shagreened above, finely granular on the throat, but coarsely granular below. The venter of frogs is usually white except for the throat, which may be peppered with brown, or a shade of green. A dark brown stripe runs from the snout through the eye and tympanum. A prominent white streak, starting below the eye, runs back over the shoulder onto the flanks, breaking up into a series of raised spots. The vomerine teeth are between the choanae and in short rows. The hindlimbs are long and the toes are partly webbed while the fingers have vestigial webbing. The finger discs and toepads are conspicuous. The species has a moderate oval inner and a small rounded outer metatarsal tubercle. The posterior thigh is light blue or purple-blue above and orange below, or orange-pink with faint brown wash above. Usually there is some blue colouration in the groin as well.¹
