Rhacodactylus willihenkeli, also known as Willi's giant geckos, are a species first identified in 2023.

Four live specimens were caught in 1987 in a forested area of New Caledonia by Friedrich Wilhelm Henkel and Joachim Sameit.

Three of the four original specimens were still alive in 2023 when DNA analysis conclusively determined them to be a unique species.

The females would lay approximately 6–8 eggs a year which would then hatch about 90 days later.

[1] The species is most genetically similar to Rhacodactylus leachianus but has different colouration.
