FRANCE. Abstract.
- Four new species of urolophid stingarees are described from the
Coral Sea (South-West Pacific): Urolophus deforgesi sp. nov. and
U. papilio sp. nov. from the continental slope of the Chesterfield
Islands; U. neocaledoniensis sp. nov. is more widely distributed
on the slopes of the Chesterfield Islands and New Caledonia and along
the northern part of the Norfolk Ridge; U. piperatus sp. nov. is
restricted to the coast of northern Queensland (Australia). The holotype
and only known specimen of a rare and unusual stingaree, U. armatus
Val. in Müller & Henle, 1841 from New Ireland (Bismark Archipelago),
is redescribed and it could represent a new genus. The new species are
mainly distinguished by a combination of the following characters: disc
shape (particularly its width), dorsal fin (present or absent), interorbital
distance (narrow or broad), tail length (short or elongated), coloration
(plain or with spots), and oral papillae, vertebrae and pectoral-fin radial
counts. A key for the urolophids of the Coral Sea is provided. |
