Mahony's Toadlet  |  

Uperoleia mahonyi

Status: Endangered on the EPBC Act list

The NSW Scientific Committee (2017) state that “Mahony’s Toadlet Uperoleia mahonyi Clulow, Anstis, Keogh & Catullo 2016 (family Myobatrachidae) is a small (males 30 mm, female 32 mm) but robustly built frog (Clulow et al. 2016). Like other members of the genus Uperoleia, this species has large parotoid glands covering the tympanum, unwebbed fingers, vomerine teeth vestigial or absent,
inguinal colouration present and presence of inner and outer metatarsal tubercles (Clulow et al. 2016). This species is distinguished from all other Uperoleia species by a combination of ventral pigment (ventral surface completely covered with black and white marbling), presence of maxillary teeth, toes unwebbed, lack of colour patch below the knee and a “squelch” as a call (Clulow et al. 2016). The belly patterns of black and white patches appear marbled, more similar to the bellies of Pseudophryne spp., rather than simply stippled as commonly observed in Uperoleia spp. (Clulow et al. 2016). Inguinal (groin) and femoral (thigh) colour patches are orange with the femoral colour patch irregular in shape and large and always closer to knee than vent (Clulow et al. 2016). Tadpoles are indistinguishable from those of other Uperoleia species (see Anstis 2013) and are described in detail in Clulow et al. (2016).”

    Uperoleia mahonyi was mainly found in late successional stages with established canopy cover; indicative of a need for native vegetation cover and suggesting that disturbance such as fire and clearing would negatively impact this species (at least in the short term) (Letnic and Fox 1997a).
