Zaupa. Host: Cupiennius getazi Simon (Trechaleidae) , adult or subadult female. Three videos show the wasp dragging the immobilized banana spider backwards on the ground. The wasp maintained the spider dorsal side upward while grasping its left pedipalp with her mandibles. Suddenly, a squareback marsh crab [ Armases ? angustum (Smith)] ( Sesarmidae ) emerged from a ground hole and, using its claw, grasped the spider from the wasp. The wasp made several attempts to retake the spider from the crab to no avail. The crab simply brushed the wasp away with its walking leg. The crab disappeared into a crevice on the ground holding the spider with its claw and the wasp flew away ( Zaupa 2020 ).
