Ceratophallus vittatus —Wallach et al., 2014: 154.

Remarks. Native to Bangka, Java, Sumatra, and Weh Islands in Indonesia (Wallach et al. 2014), X. vittatus is believed to have reached Singapore as a stowaway (Lim & Lim 1988). De Lang & Vogel (2005) incorrectly listed X. vittatus as native to Singapore. The first record of X. vittatus in Singapore was of one seen in a drain at Pandan Gardens in July 1982 (Lim & Lim 1988). Lim & Lim (1988) accepted that X. vittatus was already established in Singapore because there were three separate sightings between 1982 and 1988. Figueroa & Fantuzzi (2020) discussed that records preceding 2013 were confined to western Singapore until Fung & Chan (2014) reported one from Pulau Ubin on 2 August 2013, which also represented the first offshore record. Morgany (2018a) then photographed a dead individual in the bill of a Halcyon smyrnensis at PRP on 25 August 2018, and Figueroa & Fantuzzi (2020) added two eastern records, one from ECP on 16 June 2018 and one from PRPM on 11 September 2018. The individual photographed at PRPM in Figure 21A View FIGURE 21 on 4 January 2021 shows that X. vittatus can use mangrove habitats (H.B. Thio pers. comm.). These records suggest that X. vittatus is likely distributed throughout Singapore. Inspection of museum records reveal that X. vittatus was known from eastern Singapore even earlier. The individual from an unknown location on 2 October 1988 in Lim & Lim (1988) was collected from somewhere in Tampines, and ZRC.2.2339 was collected from Pulau Ubin on 9 November 2011. In addition, MCZ R-5676 was collected by Putnam in Singapore prior to 1886 (year the specimen was accessioned at MCZ). Given that MCZ R-938 ( Hydrophis platurus ) and MCZ R-1416 ( Eretmochelys imbricata ) were collected by Putnam in 1857 and 1858, respectively, MCZ R-5676 was likely collected around that time. There are also five specimens deposited at ZMH, but they lack any other collecting data. If indeed collected from Singapore, it is also unknown if they were collected between the time of MCZ R-5676 and Lim & Lim (1988). It may be that MCZ R-5676 and the ZMH specimens were either early stowaways or they were imported into Singapore.
