Identifying Characteristics:
Adults have a maximum SVL (snout-vent length) of 51mm. There are 8-10 supralabial scales and 7-9 infralabial scales. No precloacal pores are present. Ventral scales are smooth. There are 16-22 dorsal tubercles along the spine on the mid-body between the forelimbs and hindlimbs. The tubercles on the flanks are arranged in rows. There are multiple rows of tubercles on the tail, running along the spine but not encircling the tail. Subcaudal scales are smooth, not greatly expanded, and arranged in rows. There are 0-3 postcloacal tubercles on each side at the base of the tail. Femoral scales and sub-tibial scales are expanded. Sub-tibial scales are smooth. The subdigital scales on the first toe of the forefoot are not expanded. There are 26-32 subdigital lamellae under the fourth toe of the hindfoot.
The dorsal surface is gray with large black and pale yellow blotches. The crown and snout have reticulated black markings surrounding pale white patches. There are thin, black stripes posterior to the eye, bordered below by white, extending to the nape. The limbs have reddish-brown streaks interspersed with pale yellow streaks. The black and pale yellow markings on the tail are indistinct. The ventral surface in males is pale orange.
Biology, Ecology:
The species inhabits rock crevices in low karst forests, at altitudes of 10-250m. It is diurnal (active during the day), feeding on insects found within its distribution. It lays 2 eggs in rock crevices and tree hollows at the beginning of the rainy season each year.
Distribution:
The species is endemic to Vietnam, first discovered in 2007 in the karst forest region of Tức Dụp Mountain, An Giang province.
