Singapore records.

Crocodylus siamensis —K.K.P. Lim & L.M. Chou, 1990: 56.—K.K.P. Lim & F.L.K. Lim, 1992: 151.— L.M. Chou et al., 1994: 105.—K.P. Lim & F.L.K. Lim, 2002: 151.—N. Baker & K.P. Lim, 2008: 168.—N. Baker & K.P. Lim, 2012: 168.—Chan-ard et al., 2015: 296.

Remarks. Lim & Chou (1990) included C. siamensis in their checklist of Singapore’s herpetofauna, but listed its presence as doubtful. Although the authors do not provide references or annotation for the species, we suspect that they included it based on early confusions over C. palustris and C. siamensis . Chan-ard et al. (2015) designated C. siamensis as extinct in Singapore. Nonetheless, there are no verifiable records showing that C. siamensis ever existed in Singapore. Crocodylus siamensis is native to Cambodia, Thailand, Laos, Vietnam, and Kalimantan, but may have also existed in Java, Peninsular Malaysia, and Myanmar (Platt et al. 2018).
