Sphaerodactylus ariasae, commonly called the Jaragua sphaero or the Jaragua dwarf gecko, is the smallest species of lizard in the family Sphaerodactylidae.

Description

Sphaerodactylus ariasae is the world's smallest known reptile. The second-smallest is S. parthenopion, native to the British Virgin Islands. The Jaragua sphaero measures 14–18 mm (0.55–0.71 in){{Cite book|url=http://dx.doi.org/10.18475/cjos|title=Caribbean Journal of Science|publisher=University of Puerto Rico at Mayaguez|doi=10.18475/cjos}} from the snout to the base of the tail and can fit on a US 25-cent coin. It has an average weight of 0.13 g (0.0045 oz).{{Citation needed|date=March 2024}}

Geographic range

The geographic range of S. ariasae is believed to be limited to Jaragua National Park, in the southernmost tip of the Barahona Peninsula, in the extreme southwest of the Dominican Republic and nearby forested Beata Island on Hispaniola.

Habitat

The preferred natural habitat of S. ariasae is the leaf litter of the forest floor of dry forests with limestone substratum.

Reproduction

S. ariasae is oviparous.

Taxonomy

S. ariasae was first described by Blair Hedges, a Pennsylvania State University evolutionary biologist, and Richard Thomas, a University of Puerto Rico biologist, in the December 2001 issue of the Caribbean Journal of Science.

Etymology

The Jaragua sphaero's binomial name was chosen in honor of herpetologist Yvonne Arias, the leader of the Dominican conservation organization Grupo Jaragua, which was instrumental in securing the environmental protection of Jaragua National Park.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).
