DistributionMyanmar (= Burma) (Irrawaddy River), S Thailand, Cambodia, West Malaysia, India (Gujarat etc.), Bangladesh

baska: Bangladesh, India (Orissa, West Bengal), Myanmar, probably extirpated in Thailand; Type locality: “India”

ranongensis: Thailand; Type locality: estuaries of Ranong Province, Malay Peninsula, Thailand.  
TypesHolotype: unknown (fide NGUYEN et al. 2009)
Holotype: not given in original description [ranongensis] 
CommentSynonymy: partly after RHODIN et al. 2010. The subspecies ranongensis Nutaphand 1979 is not well differentiated and has been synonymized under baska by Fritz and Havas (2006, 2007), but no specific morphologic or genetic analysis has yet been performed to formally evaluate the status of this taxon.

Conservation: This is one of the most endangered turtle species according to a 2003 assessment by the IUCN. Not in Thailand fide CHAN-ARD et al. 1999.

Distribution: see map in TTWG 2017: 84.

Habitat: B. affinis, B. baska, and B. borneoensis are the only species living in tidal, brackish areas of the estuaries of medium and large rivers (Ernst et al. 2000)

Type species: Emys batagur GRAY 1831 is the type species of the genus Batagur GRAY 1856: 35 [1855].
