Geckonia chazaliae
Mocquard, 1895

Geckonia is a monotypic gecko genus endemic to Africa. The sole species, Geckonia chazaliae, commonly knowns as the helmethead gecko, is endemic to Morocco. The small size of G. chazaliae and its tolerance of captive conditions, have made it a more popular terrarium subject.


The specific name, chazaliae, is in honor of the yacht Chazalie, which belonged to French naturalist Raymond Comte de Dalmas (1862–1930), who collected the holotype.[2] The common name, helmethead gecko, derives from the shape of the head caused by some of the scales at the back of it.
