Conservation ActionsThere are no conservation actions in place for this species. Research into the population and distribution is recommended.
Location InformationThis species is known only from streams in the vicinity of Mbuta (sometimes spelled Mbutu) basin near Etna Bay, West Papua Province, Indonesia. The oval-shaped basin is approximately 9 km long and 3.2 km wide, along a northeastern-southeastern axis. Its south-eastern end is only 3.5 km from Etna Bay via a narrow valley flanked by 800-900 m-high ridges. The valley gradually ascends from the bay to a 200 m-high pass before opening into Mbuta Basin, which lies at an elevation of 170 m above sea level. The basin is often represented on published maps and charts as a lake, but in 1997 it was marshland surrounded by low mountains (G.R. Allen pers. comm. 2019).
Population InformationThis species was common when collected in the late 1990s, but the population trend is unknown (G.R. Allen pers. comm. 2019).
There are large fluctuations in the water level of the habitat and these are likely to be leading to fluctuations in the population. However, it is not clear if these are of great enough magnitude to be extreme fluctuations.
