With the exception of N. pelobatoides, N. albipes can be diagnosed by its unpigmented metatarsal tubercle. Neobatrachus albipes can be differentiated from N. pelobatoides by the white coloration on the top of the foot of N. albipes and N. albipes’ male call having fewer pulse numbers and higher pulse rates and dominant frequencies than N. pelobatoides (Roberts et al. 1991).
In life, the N. albipes appears to be able to change color to blend in with its background. In dark backgrounds, the dorsum is brown with markings that are dark with undefined edges. A broad lighter “V” shape can be found on the skin above and between the eyes. In light backgrounds, the dorsum of N. albipes is pale gray to light yellow-green; this is especially true around the flanks and back half of the body. In both backgrounds, the upper surface of the feet and toes are white, giving the species its common name. When preserved, the dorsal surface of the frog appears as when the live frog is on a dark background. The ventral surface, legs, upper arms and anterior of the forearms, and inner margin of the feet of the frog are creamy-white. Neobatrachus albipes has dark brown plantar and palmer areas. The skin on the anterior and lateral margins of the submandibular area is dark grey-brown. The upper surface of the foot and toes are white and the skin at the ankle is translucent showing dark brown muscle underneath (Roberts et al. 1991).
Some frogs also have a mid-dorsal strip that extends from a point level with the tympanum to the cloaca. The paratoid glands can vary in their distinctiveness and some specimens are a lighter brown-yellow when preserved. Individuals also have variation in the distinctiveness of the light bar between their eyes and some males have nuptial pads that extend to their third finger (Roberts et al. 1991).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
Breeding age males produce mating vocalizations in the spring and summer season from hidden positions in crevices or beneath woody scrub vegetation near breeding waters, which are typically 20 to 50 centimeters in depth. Vocalizations most often consist of a series of 36 to 40 brief pulses of sound. The sexes mate via inguinal amplexus (Roberts et al.1991).
Trends and Threats
While little taxon specific conservation measures are in place, approximately 8,000 square kilometers of habitat is under national or regional protection, with the largest elements of land being: Cape Arid National Park, Stirling Range National Park, Fitzgerald River National Park, and Lake Magenta National Reserve (Thackeray & Cresswell 1995).
