The Adductor Hiatus (not pictured) is a space in the attachment of the Adductor Magnus.
The Adductors originate on the pelvic bone and attach at intervals along the length of the femur. This interval attachment provides the most power and stability for the hip joint and the femur.
The Sartorius muscle is also included in this diagram though it's not technically an adductor - it acts at the hip to internally rotate the femur (a movement like you're crossing one leg over the other).
