Population Information

There is no population information available for this species, and it is known from only two specimens (Allen and Reyaan 1996). The habitat of this species undergoes fluctutations in water level and this leads to extreme fluctuations in the extent of occurrence (EOO) with at least a tenfold change in the EOO. The population of this species probably fluctuates with the water level (G.R. Allen pers. comm. 2019).


This species is under threat due to extreme water level fluctuations, with the extent of occurrence fluctuating at least tenfold. This is likely to be exacerbated by climate change.
