Integrative taxonomy, including molecular, morphological, distributional and biological data, is applied in a review of the taxonomy of the Australian species of the pest termite genus Coptotermes. The validity of the previously described species is discussed, and two new species, Coptotermes nanus, sp. nov. and Coptotermes cooloola, sp. nov., are described from the Kimberley region of Western Australia and south-east Queensland respectively. Their delimitation is based on morphological and distributional data, and the results of generalised mixed Yule-coalescent analysis of mitochondrial DNA sequence data. Images of the external view of the two new species are provided, as well as a key, based on soldier characters, for all Australian species of Coptotermes.
