Phyllidia alyta can be recognized according to following characteristics
:
- the mantle is whitish grey with 4 longitudinal black lines and black spots
at the edge
- there can be some pale yellow tubercles in the central part of the mantle
- most of the time, there is a transverse black line between the rhinophores
- the rhinophores are yellow
- the sole of the foot is grey with median black line
Phyllidia alyta is
very similar to Phyllidia
varicosa. But P. varicosa has bluish tubercles rather than
whitish ones. And yellow tubercles are many more numerous and vivid in P.
varicosa.
Phyllidia alyta could
be mistaken for Phyllidia
elegans. They can be distinguished by the shape of their tubercles
:
- P. alyta has simple and uniform in size tubercles
- P. elegans has unequally sized tubercles and the largest ones are
compound (because they consist in an aggregate of tubercles)
