Abstract:
The 16,585 base pairs mitochondrial genome of Shinisaurus crocodilurus was determined by using PCR amplification and DNA sequencing. To determine the phylogenetic position of S. crocodilurus with related species within Squamata, the phylogenetic tree was reconstructed with the concatenated nucleotide sequences of the 12 heavy-strand-encoded protein genes. Phylogenetic analyses based on maximum parsimony and Bayesian inference methods consistently support that the S. crocodilurus was closely related to the Helodermatidae within a monophyletic Anguimorpha group. And the result here contradicted the monophyly of Varanoidea (Varanidae + Helodermatidae). In addition, the Gekkonidae was found to possess a basal phylogenetic position within squamata and the traditional hypothesis of monophyletic lineages of Iguania and Scleroglossa was not supported in this study.
