Comparison of mitochnodrial CO1 sequences show that _C. intestinalis_ types A
and B (now renamed _robusta_ and _intestinalis sensu_ ) are as distant as
distinc species [[Nydam and Harrison, 2007|biblio/10.1007_s00227-007-0617-0]].
+Sequencing of nuclear genes showed intragenic recombination in C. robusta and
