Distinguishing features

Distinguishing features still need to be specified.


  • Size data has not been obtained.



Edgar (2019) records this species as Pseudobiceros strigosus and notes that it is incorrectly known as Pseudobiceros gratus. WORMS (accessed 9 Nov 2019) records P. strigosus as a synonym of P. gratus so we're leaving it under that name until further information becomes available.
