Remarks. Previously known as B. baska, Praschag et al. (2008) reidentified populations from Peninsular Malaysia and Sumatra as B. affinis . Some authors have considered B. affinis native to Singapore and extirpated ( Auliya 2007; Ng & Lim 2010; TTWG 2021), but no historical records of “native” individuals exist. Instead, there are only two records of B. affinis from Singapore, one of an individual released at SBG ( Johnson 1964), which is ZRC.2.214 and was collected on 12 September 1961, and a large individual that was seen on 9 January 1988 at USRP (Lim 1988).
