|Distribution||Australia (C Queensland)|
Type locality: 118 km W Richmond, Qld.
|Types||Holotype: AMS (AM) R116984. A neotype designation of AMS R143896, 34.4km N Barkly Highway via Normanton rd, Qld, collected R. Sadlier & G. Shea, 6.iv.1994 by Witten (1994) is invalid, as the holotype has never been missing.|
|Diagnosis||Original diagnosis: “A short-tailed member of an Agamid species com- plex widely distributed across northern Australia and readily distinguished by the following combination of characters: Snout to vent length l30.0mm; vent to tail length 117.0mm; axilla to groin length 71.0mm; head length (rostril to anterior edge of tympanum) 27.4mm; head width (tympanum to tympa- num) 25.8mm; distance between eyes 16.8mm; distance between nostrils 1O.9mm; rostril to median scale oftransverse spine row (head length) 29.2mm; 'beard' absent, but gulars keeled, more so laterally. A gravid female. Colouration (in life): Dorsally orange-brown with the head and vertebral region being dis- tinctly lighter; four pairs of whitish paravertebral blotches between the axilla and groin, with a fifth over the pelvic area; each blotch has narrow transverse contact with another, form- ing a 'dumbell' pattern; anterior-most pair extends beyond axilla to nape (in some specimens, the paravertebral blotches partly or completely coalesce); each of the enlarged dorsal spines with a dark brown leading face and orange-brown ante- riorly (this is less apparent in spines positioned laterally); enlarged ventro-Iateral spines white, but some have a brown base and white tipped; tail generally darker brown than body, with light orange-brown variegations anteriorly, that are slightly less distinct than the paravertebral blotches; last two thirds of tail with narrow, wavy bands of cream, with dark brown interspaces (in some specimens the entire tail is banded in this manner); limbs same as body, with indistinct lighter patches; head with four narrow whitish longitudinal streaks as follows - one pair extend from a point just above the nasal and extend dorso-Iaterally along the supraocular and terminate just posterior to the orbit, the other pair extend from a point approximately central on an imaginary line joining the anterior edges of the tympanum; a dark brown post-ocular streak con- tacts the anterior edge of the tympanum (where it is widest); post-ocular streak bordered above by a broad white streak extending from the orbit to just above the posterior edge of the tympanum, and below, by another white streak of varying width, originating sub-orbitally, then extending posteriorly to just below the tympanum. Ventrally, white almost patternless (though sometimes with faint brown occelli); gular region streaked with brown; undersurface of tail whitish anteriorly, but tending to be faintly brown posteriorly; lining'of mouth bright orange; iris colour bright orange. (Wells & Wellington 1985)|
Comparisons: “It has often been confused with immature Pogona vitticeps which occur in some parts of the range of P. henrylawsoni, but is easily separated by the uniform, smooth, neatly aligned (and large) ventral scales of P. henrylawsoni; in P. vitticeps the ventrals are much smaller, somewhat irregularly distributed and strongly keeled. Pogona henrylawsoni also lacks the prominent 'beard' of P. vitticeps and has a very rounded head shape, rather than the triangular shape of P. vitticeps.” (Wells & Wellington 1985)
|Comment||Synonymy: Witten (1994) erroneously considered the holotype as lost and nominated as neotype a QM specimen of Pogona vitticeps, leading him to redescribe P. henrylawsoni as a new species, Pogona brevis, now a junior synonym of P. henrylawsoni. Not listed by BARTS & WILMS (1997). Amphibolurus rankini appears to be a name circulating among herpetoculturists before it was published anywhere; it was based on the intention of Richard Wells to be published eventually. However, the species was later described as P. henrylawsoni with “rankini” left as a nomen nudum although it is possible that pictures of this species have been published under that name before 1984 (R. Wellington, pers. comm., 28 Jan 2013).|
Hybridization: P. henrylawsoni and P. nullarbor hybridize (MÜLLER 2010). P. henrylawsoni als hybridizes with P. vitticeps (MÜLLER 2002).
