The
two replicates of H. ovalis from Antigua were sequenced, with 0%
genetic variation detected between replicates. Both replicate samples
grouped with H. ovalis/johnsonii/hawaiiana in awell-supported
clade in the Bayesian analysis (Fig. 2). The percent sequence divergence
of H. ovalis from Antigua with other taxa in this clade ranged
from 0% with H. johnsonii from Florida (USA) to 0.005% with H. ovalis
from Indonesia and 0.016% with H. ovalis from Viet Nam.
