A small genus of three species, the third having been raised from subspecific status only recently. All three live in the far north of Australia. These are rather large, powerful geckos with long slender cylindrical tails.
Cogger gives other characteristics of the genus as follows: rostral and mentals rounded; labials larger than adjacenet scales; postmentals enlarged; all digits clawed, claws small and retractable within groove between apical lamellae; preanal pores present; tail somewhat prehensile, terminal subcaudal scales modified into adhesive lamellae.
|Scientific name||Common name||Distribution||Size (max)||Notes|
|P. australis||Cape York Pad-Tailed Gecko||Australia (Cape York, Queensland)||12cm SVL||An arboreal gecko, found in tropical woodland and on the edges of closed monsoonal forests and mangroves. Spends the day in hollow limbs, when it may call if disturbed by a nearby presence. Cogger suggested that this species might also be found in New Guinea. Scalation: rostral scarcely wider than high; single postanal tubercle on each side in males; dorsal scales small and smooth with the exception of those on the snout, which are large. Other: ear opening is small. Coloration: dorsally brown, either mottled or speckled with dark brown, and about 6 pale dark-edged blotches between snout and vent; some may divide to form a pair of ocelli, especially on the neck. Obscure pale blotches may be present on the flanks, and if so these may be continuations of the dorsal blotches. Dark brown bar along the side of the snout runs through the eye to the forelimb and is bordered below by white or pale brown area for some distance.|
|P. cavaticus||?||Australia (Kimberly in Western Australia)||11cm SVL||Recently raised from subspecies of P. lindneri: presumably similar in most details. Cogger described the differences with D. l. lindneri as follows: moderately heterogeneous dorsal and lateral scales (homogeneous in P. l. lindneri); colour pattern; rostral narrowly contacts nostril.|
|P. lindneri||Giant Cave Gecko||Australia (Arnhem Land in Northern Territory)||10cm SVL||Found in escarpment areas, where it forages around the openings of caves and crevices. It is especially active in the evenings in the wet season on rock faces. Scalation: similar to P. australis except for the following; snout scales small; ear opening large; rostral much wider than high; rostral does not contact nostril; 3-4 postanal scales on each side in males.|
