Paratypes. All paratypes (LSUHC 11321, 11323, 11325–36, 11339) bear the same data as the holotype.
|Diagnosis||Diagnosis. Cyrtodactylus guakanthanensis sp. nov. can be distinguished from all other Sundaland species by having the following suite of character states: adult SVL 77.7–82.2 mm adult SVL; moderately sized, conical, weakly keeled, body tubercles; tubercles present on occiput, nape, and limbs, and extend posteriorly beyond base of tail; 37–44 ventral scales; no transversely enlarged, median, subcaudal scales; proximal subdigital lamellae transversely expanded; 19–21 subdigital lamellae on fourth toe; abrupt transition between posterior and ventral femoral scales; enlarged femoral scales; no femoral or precloacal pores; precloacal groove absent; wide, dark postorbital stripes from each eye extending posteriorly to the anterior margin of the shoulder region thence forming a transverse band across the anterior margin of the forelimbs; and body bearing five (rarely four) wide, bold, dark bands. The meristic characters are scored against C. sworderi, C. tebuensis and C. quadrivirgatus in Table 5 and against all other Sundaland species in Grismer et al. (2012b: Table 5).|
Comparisons. Within the Cyrotdactylus sworderi complex, C. guakanthanensis is separated from C. quadrivirgatus by having an abrupt transition between small and large postfemoral scales and a banded dorsal pattern. From C. sworderi it differs in having fewer paravertebral tubercles (32–34 versus 36–38); lacking as opposed to having precloacal pores; having as opposed to lacking enlarged femoral scales; having wide as opposed to narrow whitish caudal bands (Fig. 1); and having a banded as opposed to spotted dorsal pattern (Fig. 1). It differs from C. tebuensis in potentially having few suprlabials (nine or 10 versus 11–13); having wide as opposed to narrow whitish caudal bands which are fewer in number (nine versus 10–14; Fig. 1); and having a banded versus a spotted or striped dorsal pattern (Fig. 1). These differences are compared between all members of the C. sworderi complex in Table 5 (GRISMER et al. 2014).
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||The specific epithet guakanthanensis is an adjective and refers to the type locality Gua Kanthan (=Kanthan Cave) within the Gunung Kanthan limestone forest.|
