|Scientific Name:||Urolophus deforgesi|
|Species Authority:||Séret & Last, 2003|
|Taxonomic Notes:||Recently resolved and described. Specifically distinct from congeners in the Coral Sea.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Last, P.R. & Marshall, L.J.|

Narrow ranging endemic stingaree known only from New Caledonia, adjacent to the Chesterfield Islands, occupying a relatively narrow bathymetric distribution (203 to 330 m). Population size unknown but taken in reasonable quantities in some trawl stations suggesting it is locally abundant and probably aggregates. Threats from fisheries are limited as there is no commercial trawling in this region. However, any major increase in fishing effort could result in rapid decline of this species, which appears to aggregate and to be reasonably range restricted. Although assessed as Least Concern at this time, fishing activities in the area will require monitoring to ensure that any changes in practice are not to the detriment of this species.
