Distribution

Santa Cruz Island, Galapagos Archipelago, Ecuador.

Remarks

Faubel (1983) considered E. horrida a very primitive species due to its of any penis papilla and seminal vesicle, its very simplified male tract, and a female system with Lang’s vesicle connected with the exterior by a Lang’s duct (ductus vaginalis). Between the two female apertures, an accessory female organ opens to the exterior independently.
