Remarks. Historically, there appears to be some confusion regarding the occurrence of N. platynota in Singapore as also noticed by Flower (1899b) who noted “its occurrence seems rather strange”.After Wallace collected five specimens (likely from BTNR or DFNP) first reported by Gray (1855) and Boulenger (1889a), no additional specimens were reported until 1897 when one was caught at a lake in SBG and Hanitsch obtained three from Seletar (Flower 1899b). One of these specimens may be ZMA.RENA.12966 deposited at RMNH by Hanitsch. Hanitsch (1898) listed N. platynota in the Raffles Museum’s catalogue, but did not specify the number of specimens. The Seletar records led Ridley (1899) to believe that N. platynota was common there, and Hanitsch (1908) also appeared to consider N. platynota common as he casually stated that it is found at Seletar, MR, and “elsewhere”. Whether Wallace found N. platynota common remains unknown. Regardless, N. platynota is rare today. Eighty-two years elapsed before N. platynota was rediscovered and reported again (Table 2). Lim (1990a) reported a large adult at SR from 4 May 1990, one from Pasir Laba Military Exercise Area from early 1990, and two hatchlings in a stream from the same area. After this, N. platynota was reported a few more times, but the last published record was from Teo & Rajathurai (1997) who listed six records that included the four sightings from Lim (1994d) and Subaraj et al. (1995). The last reported record is of the individual illustrated in Baker & Lim (2012) which was photographed at NSSF on September 2006 (Fig. 9F) (N. Baker pers. comm.).
