The authors provide a list of sequences used. Unfortunately, I see they
(claim to have) used AY436349 for COI of Sabella spallanzanii in
Sabellidae, a sequence I was warned some time ago was not of Sabella.
This sequence is probably instead from a species close to Hermodice
carunculata in Amphinomidae according to the BLAST report, and if you
try the 'related sequences' link it comes up with Hermodice! Could
hardly be more separated from what it purports to be and still be in the
annelids. Unfortunately it seems to be the only public COI sequence for
S. spallanzanii as yet in GenBank (that's also amazing!).
As far as I can see only an abstract, and not the actual paper (Peres
et al) as listed in GenBank, was ever published.
There is still no annotation to warn about this mislabeled sequence in
Genbank, so I mention it here. If actually used it doesn't appear to
have upset the analysis.
