Remarks. From early on, the occurrence of P. carinata in Singapore was known only from Boulenger (1893) who first reported it based on a specimen deposited at NHMUK collected by Dennys, and by Hanitsch (1898) who noted that this species is represented in the the Raffles Museum collection. However, the LKCNHM only has specimens from 1899, 1922, 1926, 1933, 1986, 1987, and two from 2008. After Hanitsch (1898), P. carinata was only next reported 90 years later ( Table 2 View TABLE 2 ) from a live specimen detected at SRF on 26 June 1988 ( Lim & Lim 1988a). That same year, another was seen at Singapore Zoo on 6 September 1988 ( Lim & Lim 1988b), and on Mandai Lake Road on 23 December 1988 ( Lim & Lim 1988c). Subsequent observations include a mating pair at BTNR on 12 February 1989 ( Lim & Lim 1989), two seen at NSSF and SRF ( Lim 1990a), two seen at BTNR and RRR ( Lim 1993a), one observed eating a D. caudolineatus at MNF on 8 May 1994 (Subaraj et al. 1995), a roadkill at BTNR on October 1995 (Lim 1995), and Teo & Rajathurai (1997) noted a total of 21 records during their survey, some which likely include the antecedent records. Nowadays, P. carinata is considered common (Teo & Rajathurai 1997; Baker & Lim 2012), but surprisingly, no current records have been reported aside from one seen at BTNR (Teo & Thomas 2019) and one observed eating an O. octolineatus at TNP on 6 July 2020 (Ong & Yeong 2020). LKCNHM has two specimens from 2008, Charlton (2020) published a photograph of one from DFNP, and the individual in Figure 19H View FIGURE 19 was seen at Mandai Track 15 on 21 October 2018 (I.S. Law pers. comm.).
