Remarks. Representing the latest snake addition to Singapore’s herpetofauna, P. punctata was first detected on 12 September 2014 at NSSF when two live individuals were caught in fish traps set out for an aquatic biodiversity survey (Thomas et al. 2014). One of the individuals was deposited in LKCNHM as a voucher specimen and the other was released (Thomas et al. 2014). Two months after, on 22 November 2014, an additional individual was found dead in a submerged fish trap, and contained a catfish, Clarias leiacanthus, in its stomach (Tan et al. 2014). Phytolopsis punctata likely evaded discovery due to its very specific and secretive lifestyle, being restricted to blackwater streams and peat swamps (Murphy 2007). A year later, a live individual was found in a small stream in the NSSF section of USRP on 5 December 2015 (Serin et al. 2019). An unpublished record of one seen at NSSF on 3 June 2017 is shown in Figure 24E (H. Siow pers. comm.). As NSSF is Singapore’s last remaining freshwater swamp forest, it is expected that P. punctata is confined to that area.
