Cospeciation happens when the association between two species is very close, that they may speciate in parallel. This is especially likely to happen between parasites and their hosts.
Often this type of speciation is found in symbiotic organisms.
Rarely do scientists find hosts and parasites with exactly matching phylogenies. However, sometimes the phylogenies indicate that cospeciation did happen along with some host-switching.
