Remarks. The discovery of D. rubescens in Singapore is unfortunately a consequence of forest-clearing in Changi on August 1927 which resulted in the finding of three individuals (Smedley 1928). There were no further records of D. rubescens until 66 years later on 8 February 1993 (Table 2) when a roadkill was found on PU (Lim 1993a). A few months later on 13 June 1993, another dead individual was found near the carpark at UPRP (Lim 1993b), and another roadkill was found at LP (Teo & Rajathurai 1997). Afterwards, D. rubescens was reported from one found in a shoe cupboard in a hostel at NTU on 3 November 2013 (Chua 2014), two found in 2006 and two found in 2011 at PT (Lim et al. 2016), one observed with a Draco sumatranus in its mouth at Chek Jawa, PU on 4 June 2017 (Yong 2017), and one photographed at Pasir Laba Road on 5 August 2018 (Tan 2019). The individual shown in Figure 17C was photographed on PU on 23 September 2019 (E. Goh pers. comm.).
