Mayotte, Passe en S, buoy n° 6-7, 17 m, 15 November 2003, size : 70 mm

Remarks :

In all our specimens, the pseudotentacles margin lacks the black rim

Bibliographic data :

Pseudotentacles square ruffled
   The marginal band does not continue across the pseudotentacles
   The colour pattern is probably warning colouration (aposematic)
   Ventral side is purple with the same margin as the back
   Habitat : Found under ledges on the reef slope
   Ethymology : gloriosus = glorious, for its magnificient colour pattern
   This species looks like Pseudobiceros hymanae but P. hymanae has a wide orange marginal band and black rim, but without the pink band
