The Southeast Asian lizard genus Acanthosaura is distributed throughout Myanmar, Thailand, Cambodia, Laos, China, Malaysia, and its offshore islands, Pulau Aur, Pulau Tioman, Pulau Penang, Pulau Perhentian, and Pulau Langkawi. I investigated the phylogenetic relationships of all nine of the currently recognized species of Acanthosaura using one mitochondrial gene (ND2 859bp) and three nuclear genes (KIF24 502bp; PRLR 583bp; MXRA5 860bp). Maximum parsimony, maximum likelihood, and Bayesian analyses of the mitochondrial DNA recover the wide-ranging Acanthosaura lepidogaster as a paraphyletic group. Acanthosaura lepidogaster from Vietnam, Laos, and China form a monophyletic group, but A. lepidogaster from Myanmar are sister to A. crucigera from Thailand and southern Myanmar and an undescribed species from Cambodia. Acanthosaura bintangensis and A. titiwangsaensis form a monophyletic group with A. armata. There are two distinct clades within in the A. armata clade, one from the Seribuat Archipelago and the rest from Peninsular Malaysia and its other adjacent islands. The nuclear gene trees resolve the shallow nodes except that A. crucigera comes out paraphyletic with the undescribed species from Cambodia and A. armata from Peninsular Malaysia. This could be due to incomplete lineage sorting.

The Southeast Asian lizard genus Acan-thosaura is distributed throughout Myanmar, Thailand, Cambodia, Laos, China, Malaysia, and its offshore islands, Pulau Aur, Pulau Tioman, Pulau Penang, Pulau Perhentian, and Pulau Langkawi. I investigated the phylogenetic relationships of all nine of the currently recognized species of Acan-thosaura using one mitochondrial gene (ND2 859bp) and three nuclear genes (KIF24 502bp; PRLR 583bp; MXRA5 860bp). Maximum parsimony, maximum likelihood, and Bayesian analyses of the mitochondrial DNA recover the wide-ranging Acanthosaura lepidogaster as a paraphyletic group. Acanthosaura lepidogaster from Vietnam, Laos, and China form a monophyletic group, but A. lepi-

dogaster from Myanmar are sister to A. crucigera from Thailand and southern Myanmar and an unde-scribed species from Cambodia.

Acanthosaura bintangensis and A. titiwang-saensis form a monophyletic group with A. armata. There are two distinct clades within in the A. armata clade, one from the Seribuat Archipelago and the rest from Peninsular Malaysia and its other adjacent islands. The nuclear gene trees resolve the shallow nodes except that A. crucigera comes out para-phyletic with the undescribed species from Cambodia and A. armata from Peninsular Malaysia. This could be due to incomplete lineage sorting.

Key words: Agamidae, Acanthosaura, bio-geography.
