The male in figure 18B is in the process of discharging a tapering conical spermatophore. This spermatophore is being extruded via a funnel-like structure in the oral region of the male, and the circular base that adheres to the female emerges first. The spermatophore is attached in the genital region of the female. The spinulate pads in the oral region of the male form part of the extrusion mechanism in
