Cyrtodactylus (Greek κυρτος kurtos "curved", from κυπτω kuptō "to stoop"; δακτυλος daktulos "finger, toe")[citation needed] is a diverse genus of Asian geckos, commonly known as bent-toed geckos, bow-fingered geckos, and forest geckos. The genus has about 300 described species as of 2020,[1] which makes it the largest of all gecko genera.
Instead of possessing dilated digits like other geckos, members of Cyrtodactylus have slender, curved toes to which the common names for the genus can be attributed.
The phylogenetic relationships with this genus and the genus Geckoella has not been resolved to date. Based on morphology, Bauer (2002) suggested that it was a subgenus of Cyrtodactylus but a phylogenetic study by Feng et al. (2007), though with inadequate sampling of taxa, restored it to generic status once again.[2][3] All species of Geckoella have been placed here pending a more definitive study.
The following phylogeny is from Pyron, et al. (2013),[4] and includes 22 Cyrtodactylus species. Cyrtodactylus is a sister group of Hemidactylus.[4]
The genus Cyrtodactylus contains more than 300 described species. In 2019, six new species of the Cyrtodactylus intermedius complex were identified in the Cardamom Mountains and Associated Highlands region of Southeast Asia.[5]
