title: A new species of genusFejervarya(Anura: Dicroglossidae) from northern Thailand.
abstract: We describe a new species of frog in the dicroglossid genusFejervaryafrom Ban Monjong, Omkoi District, Chiang Mai Province, northern Thailand. Analysis of DNA sequence data from the mitochondrial gene 16S, advertisement calls, and morphological distinctiveness support recognition of the new species. Matrilineal genealogy suggests that the new population from Chiang Mai is a sister taxon to the South Asian clade that includesF. syhadrensis,F. granosa, andF. pierrei. The new species,Fejervarya chiangmaiensissp. nov., differs morphologically from its congeners by its relatively small body size and proportions and the presence of dorsal warts and dermal ridges. Discovery of this new species indicates that the biodiversity of amphibians in this region remains underestimated.
