Conservation ActionsMore information on the distribution, biology, population size and trends, and the current and potential threats to this species is needed. Specifically, targeted surveys in potentially suitable habitat surrounding the type locality are needed to confirm the presence or absence of this species (H.H. Ng pers. comm. 2019).
Location InformationThis species is historically known only from its type locality at the Kali Pepe sub-drainage (of the Bengawan Solo drainage) in Surakarta, central Java (Bleeker 1846). Despite numerous surveys in the Bengawan Solo drainage (Buwono et al. 2017, Shaleh and Chakim 2018), it has not been encountered in over 170 years.
