Conservation Actions
More 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 Information
This species was historically known from either the Ciliwung or Cisadane river drainages (or possibly both) in western Java (Ng and Lim 2000). However, this species is known only from its type locality in Bogor, and despite extensive sampling in the area where it historically occurred (Hadiaty 2011), has not been encountered in over 80 years.Potentially suitable habitat exists in adjacent areas surrounding Bogor, but it is unknown if the species is extant here. Additionally, if this species is still extant here, subpopulations are expected to be fragmented (H.H. Ng pers. comm. 2019).
