Figure 29. Sequential photographs of two different (1-2, 3-8) Fan dance displays showing the attending female.

Figure 27 in Maratus candens, a new peacock spider in the linnaei group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 27. Sequential photographs of three different (1-6, 7-8, 9-13) Fan dance displays. 9-13, Note the turns of this female to follow the up and down movements of the male opisthosoma.

Figure 17 in Maratus candens, a new peacock spider in the linnaei group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 17. Lateral views of the Fan dance of a male Maratus candens based on a 100 fps video. The chart at the bottom of this figure shows the regular timing of the entire sequence, as the opisthosoma was alternately depressed in several stages to touch the underlying surface, and then elevated to the upright position (5 down+up cycles/20.72s or 0.24Hz).

Figure 12 in Maratus candens, a new peacock spider in the linnaei group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 12. Caliper dance of a male Maratus candens based on a 25 fps video. Like the wave and step display, this involves (11 cycles/7.2s or 1.5 Hz) alternation between slower separation of legs III and faster side-stepping (yellow arrows) as these legs are brought together, but legs III are brought together in a calipers configuration to surround the lowered fan, and the fan is elevated each time that these legs are separated.

Figure 3. Living type males, Maratus candens. 6 in Maratus candens, a new peacock spider in the linnaei group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 3. Living type males, Maratus candens. 6, Dorsal view of opisthosoma. 12, 14-15, Males engaged in courtship display. As in other Maratus, inflation and extension of a very flexible pedicel allows the opisthosoma to be rotated forward and then elevated in a vertical position (15).

Figure 20. Selected sequential frames from a 25 in Maratus candens, a new peacock spider in the linnaei group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 20. Selected sequential frames from a 25fps video of the Fan dance of a male Maratus candens. As in Figure 16, green arrows indicate the lower positions of the opisthosoma, touching the underlying surface at least once per cycle (4 down+up cycles/16.08s or 0.25Hz). Movement of the opisthosoma is not completely smooth, but includes some low-amplitude waving or bobbing (Figure 22). The attentive female (♀ #1) can be seen in the foreground.

Figure 18 in Maratus pinniger, a new peacock spider in the vespa group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 18. Sequence (1-16) of photographs showing a male Maratus pinniger engaged in the final phase of courtship display, showing alternation between display of the left (3, 9) and right (7, 11) flaps. Here the male extended the flaps but did not raise the fan in the centered position. Elevation of the fan appears to represent a useful form of advertisement that may not be needed when the female is actively engaged with the male.

Figure 20 in Maratus pinniger, a new peacock spider in the vespa group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 20. Photographs and sequences (1-2, 3, 4-6, 7-9) of two male Maratus pinniger engaged in courtship display. 1-2, Legs extended in a V-shaped configuration as the fan was rotated from side to side in a central position. 3, Female (in foreground) looking directly at the "feathered" left flap of the male. 4-6, Typical positions of the final phase of courtship, with the fan held in a lower position, even when centered. Note extension of legs IV to the rear. 7-9, Here the fan was elevated in the center position, apparently as an advertisement to obtain the attention of the female.

Figure 16 in Maratus pinniger, a new peacock spider in the vespa group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 16 (continued from previous page). Serial frames from a 120fps video of courtship display by a male Maratus pinniger. 12-43, 16 left-right cycles of fan rotation as the fan was raised to an elevated position, at 6.9Hz. 32-42, 4.5 cycles of right fan retraction and extension, with the fan in a median position, at 6.1Hz. 44-50, 3 cycles of fan extension and retraction at 2.0Hz. Continuous movement was accompanied by low-amplitude bobbing or vibration of the opisthosoma at ~50Hz.

Figure 15 in Maratus pinniger, a new peacock spider in the vespa group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 15 (continued from previous page). Serial frames from a 120fps video of courtship display by a male Maratus pinniger. 29-63, 17 left-right cycles of the fan as it was elevated at 7.7Hz. 65-71, 3 cycles of flap extension and retraction at 2.2Hz. All movement was fairly continuous, accompanied by low amplitude bobbing or rolling of the opisthosoma at ~50Hz.

Figure 14 in Maratus pinniger, a new peacock spider in the vespa group from southwestern Australia (Araneae: Salticidae: Euophryini)

Figure 14. Two series (1-8, 9-10) showing the female Maratus pinniger (at right) following the side to side movement of the fan by a male engaged in the final stage of courtship. As each male turned the fan to display the "feathered" flap on either side, alternating from left to right, the female, at a distance of 4-5 mm, turned to follow this movement.
