Figure 19. Consecutive frames from a 100 in Maratus playa, a new peacock spider in the fimbriatus group from Australia (Araneae: Salticidae: Euophryini)

Figure 19. Consecutive frames from a 100 fps video of courtship display by a male Maratus playa. White arrows indicate direction of movement by both legs I relative to the previous frame in this sequence (one cycle/step at ~8 Hz). Green arrows indicate movement of each pedipalp relative to the previous frame (several cycles at ~12 Hz).

Arrows indicate direction of movement by both legs I relative to the previous frame in this sequence (one cycle/step at ~11 Hz). 13-14, At the end of lateral movement the fan was rotated in the direction of movement by ~7°.

Figure 9 in Maratus nambung, a new peacock spider from the southwestern corner of Australia (Araneae: Salticidae: Euophryini)

Figure 9. Paratype females for Maratus nambung. The first of these (1-5) is more brown and less grey, with more rubbing on the dorsum.

Figure 2. 1-2, J Maratus bubo Otto & Hill 2016. 3-4, J M in Maratus nambung, a new peacock spider from the southwestern corner of Australia (Araneae: Salticidae: Euophryini)

Figure 2. 1-2, J Maratus bubo Otto & Hill 2016. 3-4, J M. cf. bubo, undescribed. Except for the bright red colour of pigmented scales on the fan, this form appears to be closer to M. nambung than to M. bubo. 5-6, J M. nambung, new species. M. bubo has a large fringe on tibia-metatarsi III, with a fan that is more rounded at the rear and marked in that place by three red lines. The other two species lack this fringe, but have a shorter fringe of black setae. The carapace of M. nambung (5-6) has a cover of brown (rather than dull red) scales, and pigmented scales of the fan are orange to red-orange rather than bright red, with a distinct black spot at the center.

Figure 22 in Maratus playa, a new peacock spider in the fimbriatus group from Australia (Araneae: Salticidae: Euophryini)

Figure 22. Positions assumed by a mating pair of Maratus playa. Here rotation of the female opisthosoma during mating was far less than the ~180° rotation observed for many other Maratus species.

Figure 19 in Maratus nambung, a new peacock spider from the southwestern corner of Australia (Araneae: Salticidae: Euophryini)

Figure 19. Selected sequential frames (100fps) from a video of a fan dance by a male Maratus nambung, facing a female. These frames represent successive positions of the fan as it was waved from side to side at a low amplitude (2-11°, average 7.54°). 12 L/R cycles over 0.69 s are shown (17.4 Hz). During this interval, the spider pivoted slightly to the right, but did not change any foot position.

Figure 17. Analysis of sequential frames (100fps) from a video of a fan dance display by a male Maratus nambung, facing a female. This includes one step to the right (9-17, large arrows) over a 0.09 s interval, including movement of legs III and low-amplitude waving of the expanded fan. Leg repositioning is identified with small, vertical arrows.

Figure 27. Male (1-2) Maratus playa and two other spiders (3-4) that may be Maratus playa, observed near Lake Goongarrie in the interior of Western Australia (references 11-12 in Table 1). 3, This could be a penultimate male. 4, Adult female. Since selection of immature and female colouration is thought be driven by their need for concealment rather than display, colouration might be expected to vary between localities.
