Range Description

This species is found only in coastal areas south of the Brunswick Heads, to Port Macquarie New South Wales, Australia. A subpopulation in Kingscliff is now thought to be extinct as repeated surveys have failed to find any individuals (C.M. Austin pers. comm. 2008).In a recent study this species was recorded from 26 sites, from the Brunswick, Clarence and Richmond River catchments, in addition to some minor coastal drainages (Coughran et al. 2008). It is further suggested this species may also be present within the Tweed River catchment where it was historically recorded (Coughran et al. 2008). Otherhistoricalrecords of this species further South toward Port Macquariefailed to yield any specimens in this recent study (Coughran et al. 2008), suggesting the range of this species may be contracting.

The extent of occurrence (EOO) of this species has been estimated to exceed 29,000 km2, although it must be noted this is based on a river basin assessment. Thus the area of occupancy (AOO) of this species is thought to much more restricted.
