Dear Alastair and colleagues,

Nereis caudata includes N. acuminata. However, Nereis arenaceodentata 
Moore 1909 is a (very) different biological species. Please enjoy reading 
Weinberg et al. (1990 Marine Biology 107:205-213); you will notice that 
these two species have a very similar morphology but they are 
reproductively isolated and their chromosome number is 2n=22 for N. 
caudata while N. arenaceodentata is 2n=18. This geographic identification 
of similar animals is also present in Diadema echinoids from each side of 
Panama; being D. mexicana the Pacific form while it is D. antillarum the 
Western Atlantic one. We should keep apart the two names of polychaetes. 
Un abrazo,
