Ong, 2022: 1 (Fort Canning Park).—Puniamoorthy et al. , 2022: 1 (Mount Serapong, [Sentosa]). Remarks. On 3 December 2015 , one individual of E. planirostris was found at a housing estate in Sembawang (Groenewoud & Law 2016). Two years later, several individuals were found at Clementi Woods on 28 July 2017 (Tay et al. 2017) and one individual was found at DFNP on 18 November 2017 (Yeo et al. 2018), suggesting either multiple introductions or rapid dispersion away from its introductory site. We believe the former to be true as the colonisation of E. planirostris at unoccupied sites appears to be linked to construction works (A. Figueroa pers. obs.). Today, E. planirostris is very common and is found throughout Singapore , including CNR (A. Figueroa unpubl. data). Native to Cuba , Bahamas , and Grand Cayman ( Heinicke et al. 2011 ), E. planirostris has established populations throughout the Caribbean, U.S. , Mexico down to South America, Hawaii, Guam , Philippines , Hong Kong , and Nigeria ( Kraus 2009 ; Ukpong et al. 2012; Lee et al. 2016 ). The main driver behind its expansion is the plant trade ( Kraus 2009 ), which is how E. planirostris is believed to have reached Singapore (Groenewoud & Law 2016). The populations in Hong Kong are regarded to have arrived via plants imported from the United States of America in the early 2000s, which in turn, exports plants to Singapore ( Lee et al. 2016 ). Molecular analysis into the origin of E. planirostris in Shenzen, China indicated that the species was introduced from Hong Kong , the Philippines , Panama , but most likely Florida , USA ( Hong et al. 2022 ). Presently, E. planirostris ’ impact to native fauna remains unknown. However, given its small size, occupancy of leaf litter, and insectivorous diet, we foresee E. planirostris possibly competing with species of Microhyla . Occurrence.
