In the present study, mitochondrial 12S, 16S and nuclear 18S, 28S rDNA fragments of ten species of spiders were amplified and sequenced. Using neighbor-joining, maximum parsimony, maximum likelihood methods and Bayesian analyses, the phylogenetic relationship between Deinopoidea and Araneoidea was inferred from the combined DNA sequences of 12S, 16S, 18S and 28S rDNA fragments. The resulting phylogeny indicated that: Deinopoidea and Araneoidea did not form single clade.
