Spinilophus armatus Müller & Henle, 1841
New Ireland stingaree, Black-spotted stingaree
Taxonomy & Nomenclature
Conservation Status
Only known from the juvenile holotype collected in the 1820's (1822-1825).
IUCN RedList assessment: Data Deficient (2006)
There have been no records of the species since the holotype was collected. It is extremely rare and possibly extinct, although fishing pressure seems almost non-existent in the reported area of collection. It is perhaps better treated as a naturally rare species with an extremely limited natural distribution.
Distribution
New Ireland, Bismark Archipelago, Papua New Guinea
Biology
Hypodigm
Holotype only.
