The putatively
unisexual diploidy has been reported also in L.
boehmei (2n=2x=34), in which all individuals are
female in Songkhla and Nakhon Si Thammarat
provinces, southern Thailand (Aranyavalai et al.,
2004). However, their genetic relationship has not
been revealed. Even though their morphology
(body color, pattern and shape) were previously
explored as the key to species identification
(Aranyavalai, 2003), this morphology might be
misleading for constructing the correct phylogeny
due to homoplasy. A consideration of molecular
information and nuclear and mitochondrial gene
sequences is appropriate for studies on both
shallow and deep genetic relationships. However,
the mitochondrial DNA sequences commonly
demonstrate saturation at basal nodes and deeper
nodes. Probably, only the nuclear data can be best
assessed to rebuild nodes at the deepest level of
the squamate tree (Townsend et al., 2004).
