Bourke, Pratt, Vanderduys & Moritz 2017
Description
"Digits broadly expanded basally and subdigital lamellae present on all digits of manus and pes. Digit I of manus and pes clawless, penultimate phalanx of digits II–V free from scansorial pad. Differs from non-Australian Gehyra by the combination of: absence of webbing between third and fourth toes, absence of a skin fold along the posterior hindlimb and very small adult size (SVL < 41 mm). Differs from all other Australian Gehyra by the combination of small body size (SVL < 41 mm), small number (≤ 6) of divided subdigital lamellae, postmentals contacting both first and part of second infralabials, one pair of outer chin shields, supranasal scales in broad contact, usually no internasal scale, and mid tan to golden dorsal background colour with pattern consisting of scattered pale ocelli and irregular dark-brown blotches on stippled background."
