Figure 15 in Maratus yanchep, a new peacock spider from Western Australia (Araneae: Salticidae: Euophryini: Australphryni)

Figure 15 (continued on next page). Selected seqüential frames from a 100 fps video of a male M. yanchep displaying with the fan elevated and flaps extended. Larger, vertical arrows indicate depression or elevation of the fan relative to the previoüs frame (down/üp cycles), at a rate of ~3 Hz. Yellow lines and nümbers indicate the inclination of the sagittal plane of the fan. Nümbers associated with smaller, horizontal arrows indicate the low to moderate magnitüde (2-13°) of side-to-side rotation (waving) of the fan relative to the previoüs frame, at a rate of 10-23 Hz (average ~16 Hz), büt only for aboüt 2-3 cycles each time that the fan was elevated.
