Cyrtodactylus pulchellus group :
1- Southern Titiwangsa Bent-toed Gecko :
Family : GEKKONIDAE
Species : Cyrtodactylus australotitiwangsaensis
Size (snout to vent) : to 12 cm
Size (total length) : ~ 27 cm
courtesy to : www.ecologyasia.com/verts/lizards/sthn-titiwangsa-bent-toed-gecko.htm
This beautiful gecko occurs in upland areas of the southern parts of the Titiwangsa Mountains in Peninsular Malaysia, such as Genting Highlands and Fraser's Hill, in hill dipterocarp and lower montane forests between 1000 and 1500 metres elevation (Grismer et al, 2012).
This species hides by day in rock crevices : it emerges only at night, but tends to stay close to its favoured crevice to which it retreats if disturbed. The images shown here are of an adult and a juvenile found living in the narrow spaces in a man-made wall built of roughly hewn blocks of stone.
The ground colour of the body of adults is fawn or beige, and there are three or four thick, pale-edged, dark brown bands across the back. The top of the head is fawn or beige, and sometimes yellowish. The tail is almost black, with six pure white bands. Juveniles lack a white tip to the tail, which occurs in some related species, for example Lekagul's Bent-toed Gecko.
Cyrtodactylus australotitiwangsaensis was formerly considered part of the 'Banded Slender-toed Gecko' (Cyrtodactylus pulchellus)species complex, however as of 2016 this group is now considered to comprise 15 separate species which occur in different parts of southern Thailand and Peninsular Malaysia (the most recent publication listing all 15 is by Grismer et al, 2016).

2- Langkawi Island Bent-toed Gecko :
Family : GEKKONIDAE
Species : Cyrtodactylus langkawiensis
Size (snout to vent) : to 10 cm
Size (total length) : ~ 23 cm
courtesy to : www.ecologyasia.com/verts/lizards/langkawi-island-bent-toed-gecko.htm
This recently described gecko inhabits forested slopes on the island of Langkawi, northern Peninsular Malaysia.
The ground colour of its body is brown or greyish brown. It bears 4, sometimes 5, dark bands extending across the body which are edged with pale scales, and it has 11 to 16 dark bands on the tail. The end of the tail is white in juveniles, which is typical of other closely-related species.
The top of the head and snout are dark brown. A thick very dark brown band, edged with pale scales, extends from behind one eye, goes over the back of the neck, and meets the rear of the other eye.
It has been postulated that this species is restricted to karst habitat, dominated by limestone rocks (Grismer et al, 2012), however the specimen shown here was found on sandstone-dominated habitat. Regardless, it is clear that this species has a preference for rock crevices near the forest floor.
Cyrtodactylus langkawiensis was formerly considered part of the 'Banded Slender-toed Gecko' (Cyrtodactylus pulchellus) species complex, however as of 2016 this group is now considered to comprise 15 separate species which occur in different parts of southern Thailand and Peninsular Malaysia (the most recent publication listing all 15 is by Grismer et al, 2016).
This species has yet to be found in any other locality, except for Pulau Langkawi (= Langkawi Island).
Specimen from forested slopes behind Datai Bay, on the north coast of Langkawi Island, Peninsular Malaysia. By day it remained hidden in a rock crevice in primary rainforest, but by night was observed foraging on the forest floor nearby. It was very shy and did not hesitate to flee back to its rock crevice when disturbed.

3- Lekagul's Bent-toed Gecko
Family : GEKKONIDAE
Species : Cyrtodactylus lekaguli
Size (snout to vent) : up to 10.3 cm
Size (total length) : ~ 24 cm
courtesy to : www.ecologyasia.com/verts/lizards/lekaguls-bent-toed-gecko.htm
Lekagul's Bent-toed Gecko, or 'Tuk-tai Boonsong', inhabits rocky outcrops in karst limestone habitat in southern Thailand, but has also been found on tree trunks in the vicinity of streams (presumably in non-karst habitat). The specimen in figures 1 and 2 was found a metre above the high tide level on coastal, limestone cliffs at Krabi.
The ground colour of this species is typically pale brown on top, and pale beneath. There are four or five thick, dark brown bands across the back of the body, which are edged with pale scales. Another broad, dark band lies across the back of the neck and extends forwards to the rear of each eye. The original tail is banded, and regrown tails are purplish.
Juveniles are yellowish, with blackish brown bands, and the end of the tail is white.
Lekagul's Bent-toed Gecko was formerly considered part of the 'Banded Slender-toed Gecko' (Cyrtodactylus pulchellus) species complex, however as of 2016 this group is now considered to comprise 15 separate species which occur in different parts of southern Thailand and Peninsular Malaysia (the most recent publication listing all 15 is by Grismer et al, 2016).
The species appears to be restricted to southern Thailand, from Surat Thani and Phang Nga provinces southwards to Satun Province (Grismer et al, 2012).

- Peters' Forest Gecko
Family : GEKKONIDAE
Species : Cyrtodactylus consobrinus
Size (snout to vent) : 13 cm
Size (total length) : 28 cm
Amongst the most beautiful of Southeast Asia's geckos, this species inhabits lowland primary rainforest or mature secondary forest.
The background colour is dark brown or blackish in juveniles, and speckled medium brown in adults. The species is easily identified by the narrow bands of white or cream across the dorsum and along the tail : in adults these bands become dark-edged. The head is decorated with a symmetrical arrangement of pale or cream reticulations.
By day this gecko will lie hidden in tree crevices, only emerging after the forest is in full darkness. It can sometimes be found near cave entrances : presumably it hides in rock crevices too.
Peter's Forest Gecko, also known as Peter's Slender-toed or Bent-toed Gecko, ranges from southern Thailand through Peninsular Malaysia and Singapore to Sumatra and Borneo.

- Kinabalu Angle-toed Gecko
courtesy to : www.ecologyasia.com/verts/lizards/kinabalu_angle-toed_gecko.htm
Family : GEKKONIDAE
Species : Cyrtodactylus baluensis
Size (snout to vent) : 8 cm
Size (total length) : 18 cm
This species occurs in the primary montane forests of Sabah, Northeast Borneo, mainly between 900 and 2200 metres elevation, although there are reports of its occurrence down to 200 metres in other parts of northern Borneo. At night it can be found clinging to gnarled tree trunks at eye-level or in crevices at the base of trees.
Its dorsal colour is light brown or fawn, with regular brownish-black bands crossing the body and tail. The back of the head may have a similar, but more broken, pattern, or it may be plainly coloured light brown. It lays two rounded eggs under the soil.
The specimen in the photograph was seen in the headquarters area of Mount Kinabalu at an elevation of 1500 metres.

- D'armandville's bow-fingered Gecko
Family : GEKKONIDAE
Species : Cyrtodactylus darmandvillei
Size (snout to vent) : 8.5 cm
Size (total length) : 18.7 cm
D'armandville's Bow-fingered Gecko was first described by Weber in 1890 (as Gymnodactylus d'armandvillei), based on a specimen from Sikka Regency, Flores, Indonesia.
The specimen illustrated here was found by day, clinging to a tree trunk at the edge of coastal secondary scrub forest at Labuanbajo, Flores. It appears to share some features with D'armandville's Bow-fingered Gecko, particularly the numerous rows of conical tubercles arranged alternately along the length of the body.
This specimen measured around 7 cm snout-to-vent, with a tail of around 9 cm (the posterior part of which has regrown). The body of this specimen is robust, flattened and with a ridge along the vertebral line. The head is large, the eyes are large, the forehead is concave and the snout is somewhat pointed. Its ground colour is light brown to buff, and the dorsum is adorned with irregular, blotchy, dark brown bands which continue onto the tail. There is a dark brown band behind the eye.
In addition to the island of Flores, D'armandville's Bow-fingered Gecko occurs on a number of other islands in central and eastern Indonesia, including Komodo, but the current populations probably represent a complex of species which require further study to ascertain their relation to each other.

- Singapore Bent-toed Gecko :
Family : GEKKONIDAE
Species : Cyrtodactylus majulah
Size (snout to vent) : 68 mm
Size (total length) : ~ 156 mm
First described in 2012, this species was formerly confused with the Marbled Bent-toed Gecko, however molecular analyses have proved it to be a separate species more closely related to a specialist group of bent-toed geckos, which includes the Panti Bent-toed Gecko, which inhabit freshwater swamp forest in various parts of Peninsular Malaysia.
In the field the species can be identified by its maximum size of 68 mm, by the blotched pattern on its dorsal surface, and the mottled pattern on top of the head.
The two examples shown here illustrate the normal variability of the species.
Little is known of the ecology of this species, except for its preference for mainly freshwater swamp forest habitat (though it has also possibly been recorded in drier forests some distance from damp, waterlogged forest).
The species occurs in the central swamp forests of Singapore, as well as the island of Bintan, in the Riau Archipelago, Indonesia.
