NOT a new Lessepsian migrant!

This note is intended to attract attention to a confusing lapsus in:

Galil B.S., Luetzen J., 1995: Biological observations on Heterosaccus 
dollfusi Boschma (Cirripedia: Rhizocephala), a parasite of Charybdis 
longicollis Leene (Decapoda: Brachyura), a lessepsian migrant to the 
Mediterranean. Journal of Crustacean biology, 15 (4): 659-670.

   The authors report that on the coast of Israel the crab Charybdis 
dollfusi, a Lessepsian migrant, may bear a serpulid polychaete when  
parasited by the rhizocephalan, the castrated crab being prevented from 
further molting.
-- p. 659, 661, 662/fig.1:  the serpulid in question is given (mistakenly!) 
as "Hydroides tuberculatus",
-- p. 669: in the acknowledgements it is given (correctly!) as Hydroides 
operculatus (identified by Helmut Zibrowius).
   In fact, the serpulid in question IS Hydroides operculatus (Treadwell, 
1929), a species already documented as a Lessepsian migrant (Ben-Eliahu & 
Ten Hove, 1992).
   "Hydroides tuberculatus" is a transcription error by Galil & Luetzen, 
for H. operculatus.
   The Mediterranean crab epibiont is NOT Hydroides tuberculatus Imajima, 
1976, a species originally described from Japan.
   Thus, presently, Hydroides tuberculatus Imajima, 1976, is NOT registered 
as a Lessepsian migrant. But let's see whether it will arrive at some later 
time, possibly as a ship-travelling species, contributing to encrease the 
biodiversity of the Mediterranean Sea ...
