Hybrids were infertile and a _C. rob_ - _C. int_ cross from two sympatric
strains from Plymouth did not develop beyond cleavage ([[Caputi and coll.,

Comparison of mitochnodrial CO1 sequences show that _C. intestinalis_ types A
and B (now renamed _robusta_ and _intestinalis sensu_) are as distant as
