CommentSynonymy mainly after FRITZ & HAVAS 2007. Trionyx maackii BRANDT 1858 was previously considered as a synonym of P. sinensis. Pelodiscus maackii and P. parviformis, both harboring distinct mitochondrial lineages, were not differentiated from P. sinensis in the nuclear markers studied by Gong et al. 2018.

Habitat: freshwater (rivers and tributaries, swamps) 
EtymologyTrionyx maacki has been named after a R. Maack, a Russian who traveled in the Amur region in the early 1850ies and who collected the type (of Trionyx maacki).
