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).
