Collar reniform with double row of 
spines not interrupted dorsally, 
spines of aboral row somewhat 
larger than those of oral row. 
Cuticular spines cover entire venter

extent. Body small, somewhat 
narrow. Acetabulum preequato- 
rial, much larger than oral sucker. 
Pharynx present. Cirrus pouch 
somewhat long, extending some-
