Distribution. Lim & Ng (1990) listed this species from the Central Catchment reservoirs; Lower Peirce Reservoir ( Ng & Lim, 1997a, 1997b; Baker, 2013b); Singapore Botanic Gardens ( Anonymous, 1988a); East Coast Park ( Anonymous, 1988a); Woodlands Town Garden ( Anonymous, 1989a); MacRitchie Reservoir ( Ng & Lim, 1997a, 1997b; Ng HH & Tan HH, 2010; Tan, 2016a); Bedok Reservoir ( Ng HH & Tan HH, 2010); Upper Seletar Reservoir ( Ng HH & Tan HH, 2010); Lower Seletar Reservoir ( Ng HH & Tan HH, 2010); Pandan Reservoir ( Ng HH & Tan HH, 2010); Upper Peirce Reservoir ( Ng HH & Tan HH, 2010); Sungei Buloh Wetland Reserve ( National Parks Board, 2003; Baker, 2014); Pangsua Pond ( Kwik et al., 2013; Tan, 2014b); Central Remarks. This species is protected under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Appendix I and breeding populations are established in the Central Catchment Nature Reserve reservoirs in Singapore ( Ng HH & Tan HH, 2010). One of the documented sources is from then-PPD (Primary Productions Department; presently divided into National Parks Board and Singapore Food Agency) (see Ng HH & Tan HH, 2010, for a more detailed account). The Singapore variants are of questionable sources, and probably the consequence of artificial crosses between recognised colour variants (Andy Yap, pers. comm.).
