|Types||Holotype: ZSI 25217 (male), collector S.S. Saha, 19 April, 1995. Paratypes: ZSI 25215 and 25216, two females, locality data as for holotype, coll. S. S. Saha, 16 and 19 April 1995.|
|Diagnosis||Diagnosis (genus): Lizards of the genus ‘Cristidorsa’ dif- fer from other closely related Draconinae genera by having the following morphological characteristics: (1) head robust and relatively wide, HW/HL mostly >70%; (2) scales of lateral head keeled; (3) nuchal and dorsal crest feeble, CL/HL<5%; (4) post-occipital and post-orbital spines absent; (5) gular scales mostly homogeneous in size; (6) size of scales on lateral jaw subequal in size across gular region; (7) single pair of distinctively enlarged conical scales present on nape above shoulder, one scale on each side of vertebral crest; (8) dorsal scale significantly heterogeneous in sizes and shapes; (9) distinct, dorsolateral rows of enlarged, keeled scales present on dorsum; and (10) V-shaped ridges present along dorsal midline, formed by enlarged, keeled scales (Wang et al. 2018: 13)|
Diagnosis: This species differs from all species of the genus Japalura by the following combination of characters; small adult size (SVL male 46.4 mm, female 52.2–58.7 mm), tail length/SVL ratio 160.5–187.5%, 10–11 SL, 9–12 IL, 45–47 MD, 17–20 4FingLam, 20–22 4ToeLam, tympanum concealed, axillary fold present, raised nuchal and dorsal crest, transverse gular fold and distinct gular pouch absent, enlarged keeled dorsal scales present, body shape subquadrangular in cross section [from MAHONY 2009].
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
Type species: Japalura otai MAHONY 2009 is the type species of the genus Cristidorsa WANG et al. 2018.
|Etymology||The Latin term ‘Cristidorsa’ means ‘ridged dorsum’, which describes the distinct, characteristic ridges on the dorsal surface of the body in the new genus. The generic name is feminine and it consists of two parts, namely ‘Cristi-’ (meaning ‘ridged’) and ‘-dorsa’ (meaning ‘dorsum’). Wang et al. 2018 suggested the English common name as ‘Ridged Dragons’ and the Chinese name as ‘棱背蜥’ (pronounced as ‘Leng-Bei-Shi’).|
The specific epithet is a noun in genitive case formed from the personal name Hidetoshi Ota of the Tropical Biosphere Research Center, University of the Ryukyus, Japan. His comprehensive work and taxonomic revisions of Japalura species have immensely contributed to our current knowledge of this genus.
