Gekkonid geckos, representing more than 85 percent of the gekkotan genera, are found on all major land masses and almost all oceanic islands in the tropics and subtropics. Intergeneric relationships of the Gekkonidae have been far more difficult to resolve than those among other gekkotan families. Our data set consists of a large number of complete mitochondrial 12S rRNA gene sequences and partial nuclear C-mos gene sequences for 33 genera of geckos, two genera of pygopods and two genera of eublepharids. Maximum parsimony (MP) and maximum likelihood (ML) trees were generated based on unweighted analysis using PAUP 4.0b10. Bayesian inference (BI) analyses trees were generated by MrBayes 3.0B4. All phylogenetic trees supported the monophyly of Gekkonidae with great confidence. The 12S data and combined data (12S and C-mos) place Sphaerodactylus deeply within gekkonine geckos, whereas Teratoscincus Pristurus are the sister group of the remaining gekkonids. However, it is known that 12S may be positively misleading when dealing with older divergences. Therefore, the conflict between the results in this study and the latest conclusions based on C-mos (Han et al., 2004) points to the need for future focus on the phylogenetic position of both Sphaerodactylus and Teratoscincus.
