Subspecies 
Common NamesEnglish: Chiku Bent-toed Gecko
Malay: Cicak Jari-bengkok Chiku 
SynonymCyrtodactylus hidupselamanya GRISMER, WOOD, ANUAR, GRISMER, QUAH, MURDOCH, MUIN, DAVIS, AUILAR, KLABACKA, COBOS, AOWPHOL & SITES 2016 
DistributionPeninsular Malaysia (Kelantan)

Type locality: Felda Chiku 7, Kelantan, Peninsular Malaysia (5° 03.318” N 102° 08.573” E; 110 m elevation  
Reproductionoviparous. Of the four adult females sampled (LSUHC 12159, 12162, 12173–74), none were gravid although one hatchling was collected (LSUHC 12177). This would suggest that C. hidupselamanya sp. nov. does not breed year-round and that April is at the end of its reproductive season (Grismer et al. 2016). 
TypesHolotype. LSUHC 12163, Adult male, collected on 19 March 2015 at 2030 hrs by Shahrul Anuar.
Paratypes. Paratypes LSUHC 12158–62, 12164–65, 12173–75 bear the same collection data as the holotype. 
CommentDiagnosis. Cyrtodactylus hidupselamanya sp. nov. can be differentiated from all other species of Cyrtodactylus by having the combination of the following characters: maximum SVL of approximately 199 mm; 8–12 supralabials; 9–12 infralabials; weak tuberculation on body; no tubercles on ventral surface of forelimbs, gular region, in ventrolateral body folds, or anterior one-third of tail; 39–48 paravertebral tubercles; 19–23 longitudinal tubercle rows; 26–33 ventral scales; 19–24 subdigital lamellae on fourth toe; no femoral pores; 17–22 precloacal pores; deep precloacal groove in males; four dark dorsal body bands; body bands as wide or slightly wider than interspaces; no rostral chevron; body bands and nuchal loop edged with a thin white, tubercle bearing lines; no scattered white tubercles on dorsum; no banding on base of thigh; 8–10 dark caudal bands on original tail; white caudal bands generally immaculate; and hatchlings and juveniles bearing white tail tips. These characters are scored across all species of the C. pulchellus complex in Table 5 (Grismer et al. 2016).

Comparisons. Cyrtodactylus hidupselamanya sp. nov. is differentiated from all other species of the C. pulchellus complex being that it is the only species with the exception of C. jelawangensis in which the posterior caudal region is whitish in adults. It is further differentiated from all other species by having a combination of weak tuberculation on body; no tubercles on the ventral surfaces of the forelimbs, on the gular region, or in the ventrolateral body folds; 19–23 longitudinal rows of dorsal tubercles; 39–48 paravertebral tubercles; 26–33 ventral scales; 19–24 subdigital lamellae on the fourth toes; no femoral pores but 17–22 precloacal pores; a deep precloacal groove; four body bands; body bands as wide or slightly wider than interspaces; body bands and nuchal loop edged with a thin white line bearing tubercles; no scattered white tubercles on the dorsum; 8–10 dark caudal bands on the original tail separated by immaculate (posteriorly) white caudal bands (Table 5). Within the C. pulchellus complex, C. hidupselamanya sp. nov. is the sister species of C. jelawangensis but separated from it on the basis of having low and rounded as opposed to prominent tubercles; lacking as opposed to having tubercles on the ventral surfaces of the forelimbs; and having fewer rows of longitudinal dorsal tubercles (19–23 versus 23–25) (Table 5 in Grismer et al. 2016).

Habitat: All specimens of Cyrtodactylus hidupselamanya sp. nov. were collected at night between 2000 and 2400 hrs inside a complex network of caves and caverns permeating and coursing through an isolated karst formation (Fig. 5). A very narrow swath of undisturbed limestone forest closely surrounds the karst formation but the forest for several kilometers beyond this has been cleared for oil palm plantations (Fig. 5). Some lizards were collected in open areas on the limestone walls near cavern entrances while others were found on walls much deeper within the cave systems. All specimens were found between 1–4 m above the cave floor. One specimen observed during the day at 1730 hrs inside the cave was taking refuge deep within a crack approximately 25 m from the cave entrance. It is likely that C. hidupselamanya sp. nov. ventures outside the caves at night to forage on the exterior walls of the karst formation although none were found. One juvenile (LSUHC 12176), however, was found on the limestone vegetation next to an exterior wall (Grismer et al. 2016). 
EtymologyThe specific epithet hidupselamanya is a modification of the Malay words “hidup selamanya” which, loosely translated means “live forever” and is in reference this species precarious future being that its limestone habitat is targeted to be completely quarried.
