If I was able to start an argument with you about the phylogeny of
parasitic protists, I guess it would be a bit special for someone who
works on parasitic ticks, mites lice, bugs, nematodes,hymenopterans,
etc., etc.. Throwing around names of species and characters, who would

Nice long threads with many different people participating can only
occur on theoretical topics like virulence.
So sad, the parasitologists around the world do not make this group a
