Remarks. Regarded as non-native to Singapore ( Baker & Lim 2012), Ng & Lim (2010) stated that the possibility exists that S. crassicollis may be native given its distribution from southern Myanmar, east to Vietnam, and south to Peninsular Malaysia, eastern Sumatra, western Borneo, and Java (TTWG 2021). Although TTWG (2021) lists S. crassicollis as native to Singapore and occurring throughout Peninsular Malaysia, its distribution in the latter is restricted to the northern states (Ng & Lim 2010). Evidence against S. crassicollis nativeness to Singapore includes its wide-ranging distribution within Singapore ( Baker & Lim 2012; refer to localities below), no individuals being reported prior to Johnson (1964), and that it is commonly released in reverence of Vesak Day (Teo & Rajathurai 1997), indicative by individuals being found with red paint ( Lim 1990a). As mentioned, S. crassicollis was first reported in Singapore by Johnson (1964), who said “[it] can be found in the catchment area, and sometimes elsewhere, but it is not very common”. As Johnson (1964) did not report on any specimens or direct field records, the first published observation of S. crassicollis came 24 years later ( Table 2 View TABLE 2 ) of one seen moving in a pond at MR on 4 April 1988 ( Lim 1988a). In addition to the published locality records listed above, S. crassicollis was also seen at JLG on 9 January 2017 (A. Figueroa pers. obs.) and KM on 30 July 2014 (T.H. Ng pers. comm.).
