Platytropius siamensis is a species of schilbid catfish (order Siluriformes) family Schilbeidae.[2] It originated from the Chao Phraya and Bang Pakong Rivers in Thailand.[1][2] It inhabited lower to middle reaches, mainstreams, tributaries, and larger marshlands.[3] The species has been declared extinct in 2011 by the IUCN Red List of Threatened Species, because despite periodic surveys it has not been encountered since 1975–1977.[1]

P. siamensis was carnivorous, feeding on insects and shrimps.[3] This species was oviparous and eggs were unguarded.[3] It could grow to a length of 20.0 cm (7.9 in) TL.[3]
