s. The small digits of the species are slender and clawed. The small beak structure is formed by the projections of the rostral and mental shields. Preanal pores are present. This gecko regulates its temperature by moving to warmer or cooler positions. The female of the species is often larger and matures at an early age, less than 1 year, which allows greater development of its eggs for increased viability of its offspring. They produce two leathery eggs. It is an
