Cuora serrata is hybrid between Cuora trifasciata and Mauremys mutica. Cuora serrata, originally described as Cuora galbinifrons serrata by Iverson & Mccord (1992) and later considered a distinct species by Obst & Fritz (1997) are hybrids as shown by the genetic studies of Stuart & Parham (2004). These hybrids are bred in the wild (evolution in progress) as mentioned Buskirk et al. (2005) ad documented for the first time in the wild by Shi et al. (2005), but not in captivity as "novelty" pets as suggested by Parham et al. (2001) and Stuart & Parham (2004), between the Keeled Box Turtle and taxa of the Indochinese Box Turtle complex. Unnamed hybrids of several other Cuora taxa are also known, as are intergeneric hybrids like Mauremys iversoni (Pritchard & Mccord, 1991), a hybrid between Cuora trifasciata and Mauremys mutica which are intentionally produced in Chinese turtle farms, see Parham et al. (2001).
