For Taenia spp., the best taxonomic review is Verster (1969?) in an
obscure South African journal - Onderstepoort (sp?) J. Vet. Sci.,
something like that.
Thompson's reviews on Echinococcus spp. are the best.
Robert Rausch (Seattle?) is a valuable contact person on the biology of
all of these species.
If you have more specific questions, contact me.
