A large Cyrtodactylus with SVL reaching 102.2 mm in adult females, males slightly smaller, up to 100.6 mm, original complete tail 114–151% of SVL; body slender; digits with well-developed claws; a single pair of postmentals in contact posteriorly; 16–20 longitudinal rows of tubercles on dorsum and 24 or 25 paravertebral tubercles; lateral folds present; 22–24 subdigital lamellae on fourth toe; 32–48 ventral scales across belly, smooth, imbricate; enlarged precloacal scales present; precloacal groove present; six pore-bearing scales in deep groove; enlarged femoral scales absent; head with paired white lines extending from the posterior margin of the nostril to the anterior margin of eye, and continuing from posterior margin of eye onto neck, forming a net-like pattern (“triangle”) on occiput.|
|Comment||This large Cyrtodactylus differs from all other Sunda Shelf species of Cyrtodactylus by the combination of a reticulated color pattern on the dorsum of the head, body banded, enlarged precloacal scales, six pore-bearing precloacal scales in a deep groove in both males and females, tubercles on forelimbs, hind limbs and occiput, absence of enlarged femoral scales, and absence of femoral pores.|
Variation. Males and females are sexually dimorphic, with females being larger than males, and exhibiting a more shallow precloacal groove. For other detailed measurements and detailed character states for the entire type series see Table 1 in RIYANTO 2012.
|Etymology||The specific epithet hikidai honors Tsutomu Hikida, one of the world’s authorities on the herpetology of Asia, in recognition of his contribution to our knowledge of the genus Cyrtodactylus.|
