About Hemitheconyx
Hemitheconyx is a genus of geckos native to Africa, distinguished by their common name, fat-tailed geckos. These reptiles share a notable resemblance to the well-known leopard gecko, suggesting potential similarities in their morphology and perhaps behavior. The genus currently comprises two recognized species: Hemitheconyx caudicinctus, also referred to as the African fat-tailed gecko, and Hemitheconyx taylori, known as Taylor's fat-tailed gecko.
Biology and Reproduction
A particularly interesting aspect of Hemitheconyx biology is their temperature-dependent sex determination (TSD) system. Observations in wild populations have shown that female geckos exhibit careful selection of nesting sites. These sites are chosen based on specific temperature ranges, with females often opting for locations around 34.2 degrees Celsius. This temperature is significant as it lies near the upper pivotal temperature for their TSD system, directly influencing the sex of the hatchlings.
Species within Hemitheconyx
The genus Hemitheconyx currently includes two distinct species:
- Hemitheconyx caudicinctus: This species is commonly known as the African fat-tailed gecko. It is one of the two representatives of the genus found on the African continent.
- Hemitheconyx taylori: Also known as Taylor's fat-tailed gecko, this species is named after the researcher Parker, who described it in 1930. It represents the second recognized member of the genus.

Frequently Asked Questions
What are Hemitheconyx geckos commonly called?
Hemitheconyx geckos are commonly known as fat-tailed geckos. This name likely refers to the characteristic thickened tail, which serves as a fat reserve.
Where are Hemitheconyx geckos found?
Hemitheconyx geckos are exclusively found in Africa. Both recognized species inhabit different regions within the continent.
Do Hemitheconyx geckos look like any other well-known geckos?
Yes, Hemitheconyx geckos are often noted to resemble leopard geckos. This similarity might extend to their coloration, patterns, and general body shape.
How do Hemitheconyx geckos determine the sex of their offspring?
In wild populations, the sex of Hemitheconyx geckos is determined by temperature during incubation. Females select nesting areas with specific temperatures, often near the upper pivotal temperature for this system.
How many species are in the Hemitheconyx genus?
There are two recognized species within the Hemitheconyx genus. These are Hemitheconyx caudicinctus, also known as the African fat-tailed gecko, and Hemitheconyx taylori, known as Taylor's fat-tailed gecko.
