Abstract
Background: The bushfrog genus Gracixalus Delorme, Dubois, Grosjean & Ohler, 2005 is found in southern and south-western China, Vietnam, Laos, Thailand and Myanmar. It is presently comprised of 17 species. In Thailand, only two species have been recorded, namely G. carinensis (Boulenger) and G. seesom (Massui, Khonsue, Panha & Eto). The latter of these two species is currently known to be endemic to the country.

New information: Based on recent field work conducted in 2019 in Doi Phu Kha National Park, Nan Province of northern Thailand, we are reporting two new records of the genus Gracixalus, G. quangi and G. yunnanensis, from Thailand, based on morphological and molecular evidence. In addition, this is the first study to report on the identification of a female specimen of G. yunnanensis. Furthermore, morphological data and natural history notes of the aforementioned species in Thailand have been provided, along with updated locations for the distribution of both species.
