There is a link at the bottom of this post, which will lead to a web page containing an abstract of a paper published in 2002. Following is a short excerpt from the abstract:
Within the 13 species of the Colubridae, there are two major clades, the Rhabdophis and Sinonatrix clade, and the Zaocys, Ptyas, Dinodon and Elaphe clade, with bootstrap values of 99 and 98 respectively. In the second clade, seven species of Elaphe form a common branch before they cluster with other genera, contrary to Dessauer's assumption of the polyphyletic origin of this genus.
