BackgroundSpiny Frog Quasipaa is a genus of frogs that belongs to a relatively poorly known group. Most of the species distribution has been recorded in China; however, a few incidences of identification have occurred in the eastern part of Indochina. To date, only one species (Quasipaafasciculispina) of Quasipaa has been recorded from Chanthaburi and Trat Provinces in south-eastern Thailand.New informationBased on recent fieldwork conducted in northern Thailand, we report a new record of Quasipaaverrucospinosa from Doi Phu Kha National Park, Nan Province at an altitude of 900–1000 m a.s.l. Our study has demonstrated that populations of this species are paraphyletic and has revealed deep genetic differences. Therefore, it is recommended that a comprehensive study be undertaken to clarify the taxonomic and geographic distribution of this species for its suitable protection and conservation.
