Body relatively short (AG / SVL 0.48) with weak, non-tuberculate ventrolateral folds; dorsal scales small and granular, interspersed with larger, low, rounded, semi-regularly arranged, weakly keeled tubercles; tubercles extending from posterior margin of occiput to anteriormost section of tail; tubercles on posterior section of body largest; 35 paravertebral tubercles; 39 flat, imbricate ventrals, ventrals much larger than dorsals; patch of enlarged precloacal scales lacking pores; precloacal groove absent. Forelimbs moderate in stature, relatively long (FL / SVL 0.16); granular scales of forearm larger than those of body, not interspersed with tubercles; palmar scales flat; digits well-developed, inflected at basal interphalangeal joints; subdigital lamellae slightly enlarged proximal to joint inflections, digits narrower distal to joint inflections; claws well-developed, sheathed by a dorsal and ventral scale. Hind limbs more robust than forelimbs, moderate in length (TBL / SVL 0.19), covered dorsally by granular scales interspersed with larger tubercles and anteriorly by flat, subimbricate scales; ventral scales of femora flat and larger than dorsals; ventral tibial scales flat and imbricate; continuous, single row of flat, enlarged femoral scales extend medially from distal region of one femur to distal region of other femur and are confluent with a series of large, flat, precloacal scales totaling 39 scales; femoral pores absent; dorsal and ventral femoral scales meet abruptly on posteroventral margin of thigh; plantar scales low and slightly rounded; digits well-developed, inflected at basal interphalangeal joints; subdigital lamellae enlarged proximal to inflected joints, digits narrower distal to inflected joints; 22 (R, L) subdigital lamellae on 4 th toe; claws well-developed, sheathed by a dorsal and ventral scale. Tail widest at base, tapering to a point, approximately last four-fifths of tail regenerated; dorsal scales on original and regenerated portion of tail flat; subcaudals flat, larger than dorsals; no median row of transversely enlarged subcaudal scales; caudal scales arranged in semi-whorls; tubercles on base of tail only; base of tail not bearing lateral, bulbous swellings; no enlarged, lateral, postcloacal scales. Coloration in life (Fig. 3). Ground color of head, body, limbs and anterior portion of tail tan; snout and top of head brown bearing darker, faint mottling; wide, dark-brown, postorbital stripes from each eye extend posteriorly across nape where they merge; faint, dark-brown, transverse line on occiput; four wide, dark-brown, well-defined, body bands with slightly lightened centers extend from forelimb insertion points on body to sacral region and separated by tan interspaces of equal width; two dark caudal bands present on original anterior portion of tail, regenerated portion of tail lacks bands; dorsal surface of limbs bearing slightly darker mottling; ventral surface of head and body immaculate off-white except for fine black stippling on gular and lateral ventral scales; ventral surfaces of limbs slightly darker with denser stippling on scales; subcaudal region slightly darker than ventral surfaces of limbs and faintly mottled. Variation. The paratypes closely resemble the holotype in overall coloration and pattern (Fig. 4). The banding pattern of the juvenile LSUHC 12204 (SVL 43.7 mm) is much more bold than that of the adults (SVL> 65.1 mm). A n transition to the more faded adult pattern is observable in the subadult LSUHC 12201 (SVL 51.6 mm). LSUHC 121999 and 12204 have five dorsal body bands whereas all the other specimens have four. Specimens LSUHC 12200 – 01 are the only specimens with original tails which are distinctly banded. The color pattern of the adult LSUHC 12206 is considerably more faded than that of the other adults. LSUHC 12199 and 12204 lack tails. Meristic variation is presented in Table 4.	en	Grismer, L. Lee, Wood, P. L., Anuar, Shahrul, Davis, H. R., Cobos, A. J., Murdoch, M. L.

DD6023449015FFB5B2CDA5DFFCD2FEBD.taxon	distribution	Distribution. Currently, Cyrtodactylus gunungsenyumensis sp. nov. is known only from the type locality of Gunung Senyum, Hutan Lipur Gunung Senyum, Pahang, Peninsular Malaysia (Fig. 1). Exploration of the adjacent karst towers of Gunung Jebak Puyoh and Bukit Terus (Fig. 5) to determine if this species occurs there as well is necessary. Natural history. Hutan Lipur Gunung Senyum is a recreational area situated around three limestone hills: Gunung Senyum, Gunung Jebak Puyoh, and Bukit Terus (Fig. 5). The northernmost hill, Gunung Senyum, is the largest, reaching 525 m in elevation and covering 1.75 km 2. Several large, open chambers and cave systems deeply incise and sculpt the periphery of this limestone hill, which is surrounded by karst forest vegetation. All specimens of the type series and two additional specimens not collected were active at night on the limestone walls or the adjacent karst vegetation (Fig. 3). Lizards were observed at night between 0 1030 and 2400 hrs on the vertical trunks of small trees as well as on thin, horizontal branches of low-growing shrubs. Lizards only occurred in areas where karst rock-rubble had accumulated at the edge of the cliff faces and where the cliff faces were eroded and exfoliated, providing cracks and holes into which lizards were able to take refuge. This species is very wary and lizards would often flee during our approach. When captured, most quickly dropped their tails and only two specimens of the nine lizards observed had complete tails. This suggests this population may be under heavy predation. No gravid females or hatchlings were observed, indicating that the breeding season is not in March.	en	Grismer, L. Lee, Wood, P.
