|Types||Holotype: MZB Lace.8659, adult male, collected 26 October 2011 by A. Riyanto.|
Paratypes. MZB.Lace.8650–58, 8660–61 and MZB.Lace.8846, same data as for the holotype, collected 24–26 October 2011 [corrected from original paper; see correction in Zootaxa 3599 (4): 400)
|Diagnosis||Diagnosis. 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.|
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.|
