Remarks. Since it was first reported from Singapore by Girard (1858b) based on specimens collected some time around 1842 during the U.S. Exploring Expedition, D. melanostictus was considered native to Singapore. Only Ng & Yeo (2012) challenged this assessment when they commented that D. melanostictus , along with Fejervarya cancrivora , F. limnocharis , Hylarana erythraea , Microhyla cf. butleri , M. cf. heymonsi , and Polypedates leucomystax , may possibly be species introduced into Singapore during early British settlement after 1819 being that each of these frogs are extremely abundant, widespread, and are found in predominantly disturbed areas. Indeed, a recent phylogeographic analysis substantiated their claim, revealing that not only is D. melanostictus introduced into Singapore, but that the Singapore population also belongs to a different species, D. bengalensis ( Jablonski et al. 2022) . Molecular samples taken from three localities (see above), along with samples from Peninsular Malaysia and Kalimantan, Indonesia formed a clade with samples from Pakistan, Nepal, India, and Bangladesh that is deeply-divergent from D. melanostictus and an undescribed species inhabiting Indochina ( Jablonski et al. 2022). Thus, given its considerably disjunct phylogeographic pattern and that the D. bengalensis clade exhibits low genetic diversity, the most plausible scenario is that D. bengalensis was introduced into Southeast Asia ( Jablonski et al. 2022). As the earliest specimens can be traced to 1842 ( Girard 1858b), this makes D. bengalensis Singapore’s earliest established non-native species. Additional early specimens of D. bengalensis were collected in 1861 by Bocourt ( Lim et al. 2019) and by Maindron in 1876 during his collection trip aboard the Corrèze. As mentioned earlier, D. bengalensis is an abundant species found in all types of habitats throughout Singapore ( Baker & Lim 2012). It went unreported from Singapore for 37 years ( Table 2 View TABLE 2 ), between Sworder (1924a) and Berry (1963).
