Justification of Red List category
This species, described in 2003, was known from a single location where its habitat has now been destroyed. It was subsequently found at several locations near to the type locality, and believed to have an extremely small population occupying a tiny range. Further surveys suggest that its range and potential population may be higher than initially suspected, but for the present it is maintained as Critically Endangered. With increased knowledge of the range and potential population of this species it is probable that it may be downlisted.
