Mottled Dwarf-Gecko (Lepidoblepharis festae)

Reptiles of Ecuador | Sauria | Sphaerodactylidae | Lepidoblepharis festae

English common names: Mottled Dwarf-Gecko, Brown Dwarf-Gecko, Festa’s Leaf-litter Gecko, Amazonian Scaly-eyed Gecko.

Spanish common names: Hojarito jaspeado, salamanquesa pestañuda oriental, geco oriental de pestañas.

Recognition: ♂♂ 8.7 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=4.2 cm. ♀♀ 8.2 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=3.9 cm.. Dwarf geckos differ from other lizards based on their small size, lack of moveable eyelids, presence of a scaly supraciliary flap, and their leaf-litter-dwelling habits.1,2 The Mottled Dwarf-Gecko (Lepidoblepharis festae) is the only member of its genus known to occur along the amazonian slopes of the Andes in Ecuador. It has a brownish dorsum with light orangish dorsolateral stripes on the anterior portion of the tail.3 This species is often confused with Pseudogonatodes guianensis, a smaller gecko that occurs on lower elevations and has white “teardrop” marks on the face.4 Males of L. festae differ from females by being more brightly colored, having a reddish-orange throat (white in females), and a silver escutcheon, a characteristic concentration of holocrine secretory glands, on the belly.

Natural history: Locally frequentRecorded weekly in densities below five individuals per locality.. Lepidoblepharis festae is a cryptozoic (preferring moist, shaded microhabitats), terrestrial, and diurnal lizard that inhabits old-growth to moderately disturbed cloud forests as well as pastures and plantations adjacent to theses forests.5 Mottled Dwarf-Geckos spend most of their lives under dense layers of moss, thick accumulations of leaf-litter, or among roots and rock piles.5 Individuals are usually found at ground level, hiding under rotten logs, rocks, surfaces debris, or piles of leaves, but some have been taken from under moss of trees up to 1.5 m above the ground. There are records of snakes (Bothrocophias microphthalmus) preying upon geckos of this species.6 In the presence of a disturbance, individuals of L. festae will quickly flee under leaf-litter.5 If captured, they can readily shed the tail as well as portions of their skin. Mottled Dwarf-Geckos are susceptible to high temperatures, dying if exposed to the sun or even if handled for longer than just a few seconds. Females lay eggs under moss, damp leaf-litter, and in crevices in dirt walls.5

Conservation: Least Concern Believed to be safe from extinction given current circumstances..7,8 Lepidoblepharis festae is listed in this category because the species occurs in all major protected areas in the Amazonian slopes of the Ecuadorian Andes (Antisana Ecological Reserve, Cayambe Coca National Park, Llanganates National Park, Podocarpus National Park, Sangay National Park, and Sumaco National Park) and it is distributed over a comparatively wide (~19,617 km2) area that retains the majority (~81%)9 of its forest cover. Therefore, the species is considered to be facing no major immediate extinction threats.

Distribution: Lepidoblepharis festae is endemic to an estimated 19,617 km2 area along the Amazonian slopes of the Andes in Ecuador. The species occurs at elevations between 1071 and 1922 m (Fig. 2).

Etymology: The generic name Lepidoblepharis, which comes from the Greek words lepidos (meaning “scale”) and blepharis (meaning “eyelash”),10 refers to the scaly supraciliary flaps that are characteristic to this group of geckos.3 The specific epithet festae honors Dr. Enrico Festa (1868–1939), an Italian zoologist who collected the holotype of the species.3

See it in the wild: Mottled Dwarf-Geckos are secretive lizards that are recorded rarely unless they are actively searched for by raking leaf-litter or by turning over rocks and rotten logs in humid, shaded microhabitats. Individuals can be found with ~5–15% certainty in Narupa Reserve, Río Zuñac Reserve, and Maycu Reserve.
