The genetic relationship was investigated of three butterfly lizard species (Leiolepis reevesii
rubritaeniata, L. belliana belliana and L. boehmei) selectively inhabiting Thailand. The findings were
based on RAG1 and C-mos gene analyses. The DNA sequences were also compared with the other
squamate reptiles. The analysis strongly supported that L. reevesii rubritaeniata was related more closely
to L. belliana belliana than to L. boehmei. The phylogenetic position of Leiolepis spp., however, was
contentious with regard to its relationship among the Leiolepidinae, Agaminae and Chamaeleonidae,
which suggested that their phylogeny remains uncertain.
