Distribution.

Currently, Hylarana bannanica is known to be distributed in Xishuangbanna Prefecture, Yunnan Province, China, as well as northern Laos (Phongsaly Province), Thailand (Chanthaburi, Ubon Ratchathani, Amnat Charoen, Sa Kaeo, Prachin Buri, Nakhon Ratchasima and Chachoengsao provinces), southwest Cambodia (Cardamon Mountains) and peninsular Myanmar (Taninthary Region), based on data from Rao and Yang (1997), Chuaynkern et al. (2004), Stuart and Emmett (2006), Yang and Rao (2008), Poyarkov et al. (2021), Zug and Mulcahy (2020), Zug (2022) and this study.

Conservation status.

Further research is required to clarify the extent of the distribution, population size, trends and conservation status of the species. Hylarana bannanica is distributed over a large area including many protected areas. Across its range, the species seems not to be rare. Thus, we tentatively suggest Hylarana bannanica be considered a Least Concern (LC) species, following the IUCN’s Red List Categories (IUCN Standards and Petitions Committee 2019).
