schistosominae: 9 shorter than

infolding of lateral edges of body. 
Suckers present. Cuticle covered 
with spines. Digestive tract simi-

commencing slightly postacetabu- 
lar, extending postequatorial; cir- 
rus sac rudimentary or absent; 
seminal vesicle free in the paren- 
chyma; prostate absent. Genital 
pore small, immediately postacet- 
abular. 9 elongate, slender, flat- 
tened; ovary elongate, loosely or 
tightly coiled, in cephalic 3rd of 
body; vitellaria extensive, occu- 
pying about two-thirds of body
