Abstract	Subsequent to the Miocene (approximately 35 Mya), Borneo has served as an insular refuge and a source of colonization for a broad range of species emigrating to others parts of Sundaland. A phylogeny-based historical biogeographical hypothesis for the Stream Toad genus Ansonia supports multiple instances of an out-of-Borneo scenario. An ancestral range estimation indicates that in situ speciation of Ansonia on the island of Borneo during the Late Miocene and Pliocene (approximately 2–13 Mya) eventually resulted in an invasion of the Philippines, Sumatra, and two independent invasions of the Thai-Malay Peninsula. When collecting material for the biogeographical analysis, a new species of Ansonia, Ansonia khaochangensis sp. nov. was discovered in a limestone cave from the Khao Chang karst tower in Phangnga Province, in southern Thailand. Ansonia khaochangensis sp. nov. can be differentiated from all other species of Ansonia by having a unique combination of morphological and colour pattern characteristics. Phylogenetic evidence based on the mitochondrial genes 12S and 16S indicates that it is nested within a clade of other species distributed north of the Isthmus of Kra. The cave lifestyle of this new species is a unique and a significant departure from lotic environments common to most other species of Ansonia. The reproductive biology of this species is unknown.
