First national record of Quasipaa verrucospinosa (Bourret, 1937) (Amphibia: Anura: Dicroglossidae) from Thailand with further comment on its taxonomic status

Spiny 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 (Quasipaa fasciculispina) of Quasipaa has been recorded from Chanthaburi and Trat Provinces in south-eastern Thailand.Based on recent fieldwork conducted in northern Thailand, we report a new record of Quasipaa verrucospinosa 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
