Sharp-snouted Dwarf-Gecko (Lepidoblepharis intermedius)

Reptiles of Ecuador | Sauria | Sphaerodactylidae | Lepidoblepharis intermedius

English common names: Sharp-snouted Dwarf-Gecko, Lowland Scaly-eyed Gecko.

Spanish common names: Hojarito hocicudo, gecko pintado.

Recognition: ♂♂ 6.3 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=2.9 cm. ♀♀ 7.3 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=3.4 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 Sharp-snouted Dwarf-Gecko (Lepidoblepharis intermedius) differs from other members of its genus occurring in the rainforests of northwestern Ecuador by its medium-size, sharp snout, and homogenous granular dorsal scales.3,4 The dorsal surfaces are orangish brown with (usually) a whitish streak across the nape.5 In Ecuador, the other two co-occurring Lepidoblepharis species (L. grandis and L. peraccae) have blunt snouts. Males of L. intermedius differ from females by their bright red tail and by having a silver escutcheon, a characteristic concentration of holocrine secretory glands, on the belly.

Natural history: Extremely rareTotal average number of reported observations per locality less than three.. Lepidoblepharis intermedius is a cryptozoic (preferring moist, shaded microhabitats), terrestrial to semi-arboreal, and diurnal lizard that inhabits old-growth evergreen lowland and foothill forests.6 When not active, Sharp-snouted Dwarf-Geckos hide under logs or piles of rotten coconuts.7 In the presence of a disturbance, individuals will quickly flee under surface objects.7 If captured, they can readily shed the tail as well as portions of their skin.6 This species is oviparous.8

Conservation: Least Concern Believed to be safe from extinction given current circumstances..9 Lepidoblepharis intermedius 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.9 The main threat to the long-term survival of populations of L. intermedius 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 ~61% of the habitat of the species has been destroyed.10 Therefore, the species may qualify for a threatened category in the near future if this threat is not addressed.

Distribution: Lepidoblepharis intermedius is endemic to the Chocó biome, from western Colombia to northwestern Ecuador. The species occurs at elevations between 0 and 920 m (Fig. 2).

Distribution of Lepidoblepharis intermedius in Ecuador

Etymology: The generic name Lepidoblepharis, which comes from the Greek words lepidos (meaning “scale”) and blepharis (meaning “eyelash”),11 refers to the scaly supraciliary flaps that are characteristic to this group of geckos.12 The specific epithet intermedius probably refers to the body size of this gecko, which is intermediate among members of the genus.13

See it in the wild: Sharp-snouted Dwarf-Geckos are rare and secretive lizards that are recorded no more than once every few moths at any given locality. The majority of the observations come from Gorgona, an island off the Colombian Pacific Coast. In this island, individuals of Lepidoblepharis intermedius were taken mostly from under piles of rotten coconuts.
