This species is short-listed by Dijkstra and Vick (2004) as western African odonate requiring special attention. It is known from one locality, the Sinoe River and a tributary, within a 5,000 km² area of forest habitat, which is expected to deteriorate in the future due to selective logging and clearing for agriculture. It is therefore listed as Endangered.
