Figure 35. Consecutive but not sequential frames selected from a 25 in Five new peacock spiders from eastern Australia (Araneae: Salticidae: Euophryini: Maratus Karsch 1878 and Saratus, new genus)

Figure 35. Consecutive but not sequential frames selected from a 25fps video of the courtship display of a male Maratus cinereus, to illustrate successive positions. Leg movement is highlighted with arrows. There was some movement of the fan during this sequence but it was not waved. Even when both legs III were moved rapidly (10-21), their movement was not synchronized or bilaterally symmetrical.

Arrows indicate movement of legs III, rotation of the fan, and side-stepping relative to the preceding frame. In this sequence symmetrical (1-6) and assymetrical (10-18) waving of legs III can be seen. Note the range of elevations of legs III, including near-vertical positions.

Figure 66. Sequential but not consecutive frames from a video (25 FPS) of courtship display by a male Maratus gemmifer facing a female. Arrows indicate rotation of the fan, movement of the extended legs III, or side-stepping relative to the preceding frame. When the male side-stepped in front of a female, the leading leg III was raised and the trailing leg III lowered as shown here (18-20).
