Remarks. Nyctixalus pictus is a phytotelma breeder ( Inger et al. 2017), and thanks to unpublished research from students at NUS demonstrating that it successfully breeds in artificial containers, N. pictus was added to NParks species recovery plan (NParks 2017). NParks anticipates adopting the artificial breeding container method to translocate tadpoles to suitable areas in hopes of expanding N. pictus’ distribution in Singapore. A pilot study was done between December 2017 and March 2018 using this method to translocate individuals to the remnant primary forest patch in SBG Rain Forest (Ng & Taha 2021). Fortunately, the pilot study proved successful and N. pictus has successfully established a population at the translocation site.

Hanitsch collected the first Singapore specimen of N. pictus (and the first specimen for the Malay Peninsula) in 1896 at BTNR ( Flower 1896). Evidently, N. pictus was rarely collected historically. Aside from Hanitsch’s specimen, only three larvae in the Raffles Museum dated 1933, two specimens from Hendrickson dated 1958 at BPBM, and two specimens from Berry and Goh dated 1959 deposited at BPBM are known. The two specimens that Taylor (1962) examined were those collected by Berry and Goh. Lim & Yang (1991) reported only one specimen at LKCNHM, which was collected by Murphy in 1980. Thus, after Hanitsch’s specimen, the next published field observation of N. pictus was 101 years later ( Table 2 View TABLE 2 ) by Teo & Rajathurai (1997) who found it common at BTNR and who discovered the first population outside of BTNR at NSSF in 1996. Although seldom reported in the literature, N. pictus is common and even tolerates degraded forests (A. Figueroa pers. obs.).
