|Diagnosis||Diagnosis. A medium-sized (maximum SVL 115.6 mm) agamid lizard with two pairs of spines: postorbital (supraciliary) spines and spines on occiput between tympanum and nuchal crest; tympanum naked; moderately developed gular pouch; scales on flanks randomly intermixed with medium and large scales; nuchal crest |
present and strongly developed; diastema between the nuchal and dorsal crests present; dorsal crest slightly developed, composed of enlarged, pointed scales beginning at shoulder region and decreasing regularly in size; tail 1.56–1.85 times SVL; black nuchal collar present; black eye patch present; black oblique folds anterior to the fore limb insertions present.
The new species can be separated from all congeners by having different numbers of subdigital lamellae on the fourth finger (19–21) and toe (25–28), and a different shape of the black eye patch, that extends from posterior margin of nostrils through orbit posteriorly and downwards beyond the posterior end of the tympanum but neither meeting the diamond shaped black nuchal collar on nape nor black oblique humeral fold.
|Etymology||The name refers to Tongbiguan Nature Reserve, the locality where the new species was found.|
