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 (Ng H.H. pers. comm. 2019).
Location InformationThis species is described from two specimens collected at the Muar River at "Tubing Tinggi"[=Kampung Tebing Tinggi] in the southern Malay Peninsula (Duncker 1904). It is only known from the type material (Ng and Kottelat 1998). Given only one collection record, it is difficult to accurately estimate extent of occurrence (EOO) or area of occupancy (AOO). However, the AOO is assumed to be 4 km2 based on current collections, the specific habitat preferences of close congeners, and extensive habitat degradation surrounding the type locality (H.H. Ng pers. comm. 2019). Recent non-target surveys in the upper Muar drainage failed to detect this species (Jeffrine et al. 2005, Halim et al. 2018). Extensive targeted surveys are needed to determine the presence or absence of this species in potentially suitable habitat surrounding the type locality.
