17. Broad tapeworm - Moniezia expansa
The life cycle of Moniezia expansa involves sheep as the definitive host and soil mites as the intermediate host.  The tapeworm's eggs are passed in the sheep's feces, and mites are infected when they eat the eggs; the metacestode stage in the mite is called a cysticercoid.  Sheep are infected when then ingest infected mites. This species of tapeworm is unusual in that each proglottid contains two sets of female reproductive organs

19. Hymenolepis nana (the dwarf tapeworm)
Geographical distribution
Location in host:

Morphology:
It is a very short tapeworm, measuring mm and has approximately 200 proglottids.
Scolex :
retractible rostellum with a single row of small hooks and 4 suckers.
Neck is long and slender.
Mature proglottids are broader than long with a single common genital pore on one side of strobila.
