Remarks. A consequence of urban development, I. paucisulcus View in CoL was first discovered in Singapore in 1904 ( Hanitsch 1905) when Bell collected one during excavations of the MacRitchie (then known as the Impounding) Reservoir (Hanitsch 1908). Ichthyophis paucisulcus View in CoL was not recorded again until 80 years later when one was found in mud in a stream at Jungle Fall Valley on 29 March 1984 (Ng et al. 1988). However, CAS 7424 apparently went overlooked as it was collected on 10 October 1940 from an unknown location. The third reported specimen was of a larva seen on a student’s shoe on 14 February 1989, also at Jungle Fall Valley (Ng et al. 1989a). After the fourth specimen was observed at NSSF on 7 September 1990 ( Lim 1990b), I. paucisulcus View in CoL went unreported for another 25 years, until freshwater biodiversity surveys at BTNR detected two individuals. The first was a juvenile found hiding in submerged leaf litter on 23 February 2015 ( Fig. 4A View FIGURE 4 ) and the second was a smaller individual that was found at the same location on 25 March 2015 (Lim et al. 2015).
