Remarks. Native from central Vietnam to southern China and Taiwan (Frost 2017), S. guentheri was first documented in Singapore in 2010 at SBWR based on its call (Chan & Goh 2010). However, S. guentheri was apparently known from at least 1997 from Jurong Bird Park also based on its call, and separately from a photograph taken on 10 May 2008 (Leong & Lim 2011). Presently, S. guentheri is well-established, common, and widespread throughout western and central Singapore (Ng & Yeo 2012; Lim & Ng 2015). Leong & Lim (2011) and Ng & Yeo (2012) suggested that S. guentheri arrived from southern China as stowaways in ornamental plants, ornamental fishes, or with food. As of now, S. guentheri is restricted to urban areas and does not appear to be invasive; however, S. guentheri is known to have toxic secretions that may prove lethal to other frogs or predators, and it is also host of the parasitic roundworm, Angiostrongylus cantonensis, which can cause angiostrongyliasis in humans if they consume raw or undercooked intermediate hosts of this parasite, such as freshwater snails, crustaceans, or frogs (Ng & Yeo 2012).
