|Higher Taxa||Gekkonidae, Gekkota, Sauria, Squamata (lizards: geckos)|
|Common Names||E: Northern Kimberley gecko|
|Synonym||Gehyra pluraporosa BOURKE, DOUGHTY, TEDESCHI, OLIVER, MYERS & MORITZ in DOUGHTY et al. 2018: 224|
|Distribution||Australia (Western Australia)|
Type locality: King Edward River, Western Australia (14.75373°S; 126.21050°E).
|Types||Holotype: WAM R174024 (male), collected on 7 March 2014 by Doughty, P., Ellis, R.J. & Catullo, R. Paratypes (4). All from Western Australia: WAM R174026 (subadult), King Edward River west (14.75413°S; 126.21037°E); WAM R176170 (CCM0918) (male), King Edward River campsite, 30 km north of Theda Station homestead (14.51903°S; 126.45811°E); WAM R176372 (CCM5962, TS32) (female) and WAM R176373 (CCM5963, TS33) (female), Bruces Ck, Theda Station (15.65862°S; 129.65944°E).|
|Diagnosis||Diagnosis. A Gehyra with small body size (average 43 mm, 39–46 mm SVL), no flap of skin between limbs, ~2/3 of dorsal half of rostral deeply furrowed with groove, internasal usually present, 2 postnasals with upper larger than lower, first supralabial not taller than second, 2 pairs of chin shields, snout short and straight to convex in lateral view, first digit of manus and pes without protruding claw, 6 or 7 divided subdigital lamellae on fourth toe, 25 or 26 pre-cloacal pores in males in chevron with outer edges curving anteriorly along thighs. Background colouration in life light purplish-brown; alternating pattern of short pale yellowish- white transverse bars to either side of midline formed by irregular-shaped pale blotches or spots, and dark poorly-defined bands on the dorsum with extensive pale yellow to orange white stippling over dorsal surfaces including head, limbs and tail.|
Comparisons with other species. Gehyra pluraporosa sp. nov. is most similar to other small-bodied species (SVL <50 mm) from the Kimberley. However, the numerous pores in males distinguish it from all other such species. In addition, in 4 of 5 specimens the upper postnasal is much larger than the lower postnasal (vs similar in size compared to other G. nana group species), the first supralabial is not taller than the second (vs first taller) and the rostral is deeply furrowed (vs moderately grooved), although a larger sample size would test the utility of these diagnostic characters. Gehyra pluraporosa sp. nov. also has a distinctive dorsal pattern, lacking the clearly-defined dark spots of most other G. nana group species and having transversely elongate dark markings that alternate with rows of smaller white spots. In addition, the background colour is heavily marked with fine stippling (vs plain). In life, there are yellow to purple hues in the dorsal patterning which is also unique for small Kimberley Gehyra.
|Comment||Habitat. This species has been collected from sandstone rock formations in open woodlands. Its geographic range overlaps those of G. nana (lineage nana4), G. australis, G. koira and G. multiporosa, and it occurs sympatrically with the larger G. xenopus.|
Distribution: see map in Doughty et al. 2018: 203 (Fig. 1).
|Etymology||pluraporosa is a combination of plurus (Latin) for ‘many’ and refers to numerous pre-cloacal pores observed in males of this species; also an allusion to the Kimberley G. variegata group species G. multiporosa which has a larger body size and over 50 pre-cloacal pores.|
