Chocoan Dwarf-Gecko (Lepidoblepharis peraccae)
Reptiles of Ecuador | Sauria | Sphaerodactylidae | Lepidoblepharis peraccae
English common names: Chocoan Dwarf-Gecko, Chocoan Scaly-eyed Gecko, Peracca’s Dwarf-Gecko.
Spanish common names: Hojarito del Chocó, hojarito de Peracca.
Recognition: ♂♂ 5.8 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=2.7 cm. ♀♀ 5.7 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=2.6 cm.. Dwarf geckos differ from other lizards based on their small size, lack of movable eyelids, presence of a scaly supraciliary flap, and their leaf-litter-dwelling habits.1,2 The Chocoan Dwarf-Gecko (Lepidoblepharis peraccae) differs from other members of its genus occurring in the rainforests of northwestern Ecuador by being smaller in body size and having homogeneous granular dorsal scales.3,4 This species resembles L. buchwaldi, a gecko that occurs in the seasonally dry forest ecosystem rather than in the Chocó rainforest. Males of L. peraccae differ from females by having a reddish throat (white in females) and a silver escutcheon, a characteristic concentration of holocrine secretory glands, on the belly.

Natural history: Lepidoblepharis peraccae is a terrestrial and diurnal lizard that inhabits old-growth to moderately-disturbed evergreen lowland and foothill forests.5 Chocoan Dwarf-Geckos are cryptozoic, spending most of their lives in thick accumulations of leaf-litter, especially along streams.5 When not active, they hide under logs or piles of leaves.5 In the presence of a disturbance, individuals of L. peraccae will quickly flee under leaf-litter. If captured, they can readily shed the tail as well as portions of their skin.5
Conservation: Least Concern Believed to be safe from extinction given current circumstances..6,7 Lepidoblepharis peraccae is listed in this category because the species is widely distributed throughout the Chocoan lowlands, especially in areas that have not been heavily affected by deforestation, like the Colombian Pacific coast. Thus, the species is considered to be facing no major immediate extinction threats.6 The main threat to the long-term survival of populations of L. peraccae is the continuing decline in the extent and quality of its habitat, mostly due to encroaching human activities such as agriculture and cattle grazing. In Ecuador, an estimated ~62% of the habitat of the species has been destroyed.8 Therefore, the species may qualify for a threatened category in the near future if this threat is not addressed.
Distribution: Lepidoblepharis peraccae is native to the Chocó biome, from western Colombia to northwestern Ecuador (Fig. 2).

Etymology: The generic name Lepidoblepharis comes from the Greek words lepidos (=scale) and blepharis (=eyelash),9 and refers to the scaly supraciliary flaps.10 The specific epithet peraccae honors Mario Giacinto Peracca (1861–1923), an Italian herpetologist who described the genus Lepidoblepharis.10
See it in the wild: Although secretive, Chocoan Dwarf-Geckos can be seen with almost complete certainty by carefully raking leaf-litter in forested areas throughout the species’ area of distribution. The species is particularly abundant in Centro Científico Río Palenque, Río Silanche Bird Sanctuary, and Kapari Lodge.
