The genus has no established common name, but many individual species are referred to as spiny frogs.

They occur in East and Southeast Asia, from Thailand and Cambodia to southern and eastern China.

[1] Quasipaa was first proposed as a subgenus of Paa (now considered to belong to Nanorana).

It was subsequently raised to the level of genus, and molecular phylogenetic analyses have corroborated the monophyly of Quasipaa.

[1] Even after splitting the very wide Rana into smaller taxa, frogs now in Quasipaa continued to belong to the true frog family (Ranidae), at times as subfamily Dicroglossinae, until Dicroglossinae was raised to the family level (i.e., Dicroglossidae).
