Nemonte’s Anole (Anolis nemonteae)

Reptiles of Ecuador | Sauria | Dactyloidae | Anolis nemonteae

English common names: Nemonte’s Anole, Star Anole.

Spanish common names: Anolis de Nemonte, anolis de las estrellas.

Recognition: ♂♂ 37.3 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=11.5 cm. ♀♀ 33.5 cmMaximum distance from the snout to the tip of the tail. Snout–vent length=10.3 cm..1 Anoles are easily distinguishable from other lizards by their diurnal habits, extensible dewlap in males, expanded digital pads, and granular scales on the dorsum and belly.2 The Nemonte’s Anoles (Anolis nemonteae) is the largest anole in southwestern Ecuador.1 It can be distinguished from the other three species of Anolis with which it co-occurs (A. binotatus, A. fasciatus, and A. festae) on the basis of its large size, fleshy crest behind the head, and unique coloration. The dorsum is greenish to pale cream with faint darker bands and numerous circular blotches made of a whiter pigment. The dewlap is large and uniformly cream in males, and yellow with dark green blotches in females. The iris is reddish brown.1 Juveniles of this species may be difficult to tell apart from individuals of A. fasciatus, but the iris of the latter is bluish.

Natural history: Locally frequentRecorded weekly in densities below five individuals per locality.. Anolis nemonteae is a diurnal and arboreal lizard that inhabits humid evergreen foothill forests, forest borders, and teak plantations.3 At night, individuals have been found sleeping horizontally on banana leaves, Toquilla palms, ferns, and branches 0.4–7.4 m above the ground.1,3 In captivity, one female laid one egg that hatched after an incubation period of 129 days (slightly over four months).1 There is an unpublished record of a Long-wattled Umbrellabird (Cephalopterus penduliger) preying upon an individual of this species.4

Conservation: Critically Endangered Considered to be facing imminent risk of extinction.. Anolis nemonteae has not yet been formally evaluated by the IUCN. Here, it is proposed to be assigned to the Critically Endangered (CR) category following IUCN criteria5 because the species’ extent of occurrence is estimated to be around 87 km2, which is less than the 100 km2 threshold to qualify for CR. The species is known only from three localities,1,6,7 and in two of these, the local population is probably already extirpated. Only the population within Buenaventura Reserve is well protected. El Oro province has the sixth highest deforestation rate among Ecuador’s 24 provinces.8 The expansion of Buenaventura Reserve is probably the best strategy to prevent A. nemonteae from going extinct.

Distribution: Anolis nemonteae is endemic to an estimated ~87 km2 area along the Pacific foothills of the Andes in southwestern Ecuador. The species has been recorded only in three localities within El Oro province at elevations between 45 and 1059 m (Fig. 2).

Distribution of Anolis nemonteae in Ecuador

Etymology: The generic name Anolis is thought to have originated from Cariban languages, specifically from the word anoli, which is the name Arawak peoples may have used to refer to this group of lizards.9 The specific epithet nemonteae is a patronym honoring indigenous activist Nemonte Nenquimo, in recognition of her braveness and determination to protect natural forests and their inhabitants.1

See it in the wild: Star Anoles are only frequently observed within the limits of Buenaventura Reserve. Most individuals have been spotted sleeping on vegetation along the main dirt road that connects the reserve’s system of trails.
