discussion

Remarks. Sworder (1924) discussed that Smith informed him of two specimens of R. subminiatus that he obtained in Singapore, but it is unknown whether Smith personally collected or purchased the specimens. Furthermore, those specimens were not deposited in any museums, and Smith (1930) did not discuss his findings in his account of the species. Buddle (1929) reported one he purchased at SNB; however, the description he provided of “ uniform blackish on dorsum and light on venter, under part of neck crimson ” does not depict R. subminiatus, but instead more closely matches R. flaviceps. Later in 1994, a single individual of R. subminiatus was discovered at Mandai Track 15 on 15 January 1994 (Subaraj 1994), but may have been an escapee from Singapore Zoo (Teo & Rajathurai 1997). Teo & Rajathurai (1997) considered the individual as a rediscovery of R. subminiatus in Singapore, but acknowledged that its distribution in the Malay Peninsula only reached as far south as extreme northern Peninsular Malaysia (Wallach et al. 2014). Nonetheless, R. subminiatus was still considered native to Singapore and was even treated as critically endangered (Davison 2008) or extinct, if not rare (Lim & Li
