Figure 6 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)

Figure 6. Views of the two female types (1-8, 9-13) for Maratus fimbriatus. These have a fairly uniform 'salt and pepper' colouration. On the anterodorsal midline is a black figure in the shape of a two-headed arrow, and behind this on either side is a lighter coloured triangular spot (9). These may assist in the field identification of this species.

Figure 2. Dorsal opisthosoma of 15 male Maratus fimbriatus from the collection of the Australian Museum, Sydney. The catalog number of each specimen is shown at the upper right of each photograph (Table 1). The width and distance between the two white stripes varies. In some specimens these stripes converge to either the front (e.g., 11) or the rear (e.g., 14); in other examples (e.g., 1) they are nearly parallel. In most cases (e.g., 13, arrows) a fine posterior-lateral notch interrupts each stripe. This feature may also be observed in the male types (Figure 1).

Figure 12 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)

Figure 12. Display by a stationary (not stepping) male M. fimbriatus directly in front of a female (sequential 25 fps video). The fan was rotated from side-to-side (~2/s cycles), and the pedipalps were alternately moved apart and then brought together.

Figure 1 in Maratus fimbriatus, a new peacock spider from the Darling Riverine Plains of New South Wales, with a review of the Maratus chrysomelas group (Araneae: Salticidae: Euophryini)

Figure 1. Views of holotype (1-6) and paratype (7-12) male Maratus fimbriatus. When retracted, the fringes join to form a sharp white tip at the end of the opisthosoma (10). When expanded during courtship display (11, 12), the light blue, iridescent colour of these fringes is revealed to the female.

Figure 16 in Maratus elephans, a new member of the volans group from New South Wales (Araneae: Salticidae: Euophryinae)

Figure 16. Known localities for the three members of the volans group (M. elephans, M. pardus and M. volans). Numbered localities are associated with records that have been verified from photographs (many posted on FLICKRTM), by the examination of specimens, or listed in previous publications. For each listed locality, the respective collector and/or photographer and/or examiner is given. Unverified records of M. volans from the Atlas of Living Australia (http://bie.ala. org.au/species/Maratus volans) are not numbered, and some of these posted records (e.g., west of Melbourne, or Tasmania) are not shown here as they are now known to represent other species.

Figure 14. Sequential but not consecutive video frames (25FPS, exposure 20 msec/frame) showing elevation and extension of legs III and waving of the opisthosoma by a female Maratus elephans in the vicinity of a male. Arrows indicate the direction of movement of the fan relative to its position in the previous frame.

Figure 15 in Maratus elephans, a new member of the volans group from New South Wales (Araneae: Salticidae: Euophryinae)

Figure 15. Displaying males of the three species associated with the volans group of the genus Maratus. 1-3, M. elephans from Andersons Flat near Chaffey Dam, NSW. 4-6, Three different M. pardus from Cape Le Grand National Park, WA. 7-9, Three different M. volans from Ku-ring-gai Chase National Park, NSW. The position of legs III relative to the fan varies in the three species from (2) one leg in front and one behind in M. elephans, to (5) both legs in front in M. pardus, to (8) both legs behind in M. volans. All three species are vividly and distinctly coloured.

Figure 10 in Maratus elephans, a new member of the volans group from New South Wales (Araneae: Salticidae: Euophryinae)

Figure 10 (continued from previous page). Complete cycles of display (legs III lowered and raised as fan is waved) are represented by frames 20-23, 23-28, and 28-33 (rate of 5-8 cycles/s). Elevation of legs III (e.g., blurred movement in frame 27) is relatively fast and continuous, but lowering may be interrupted.

Figure 11 in Maratus elephans, a new member of the volans group from New South Wales (Araneae: Salticidae: Euophryinae)

Figure 11. Sequential video frames (25FPS, exposure 20 msec/frame) showing continuous movement during the fan dance of a male Maratus elephans viewed from the rear. In this sequence cycles were slower (about 2-3 cycles/s, frames 8-19), and legs III were not moved continuously, and were not lowered to the extent as shown in Figure 10. Arrows indicate the direction of movement of the fan relative to its position in the previous frame.

Figure 9. Positions assumed during the fan dance by male (♂ #1, 2) Maratus elephans facing a female. 2, Here both elevated legs III were held behind the fan. More often one leg III was held in front of the fan, and one behind the fan, in this position (1, 4, 5). 8-9, Rear views.

Figure 5 in Maratus elephans, a new member of the volans group from New South Wales (Araneae: Salticidae: Euophryinae)

Figure 5. Views of the living female paratype for Maratus elephans. These closely resemble the females of M. volans, but unlike that species lack spots of dark pigment on the legs and flecks of dark pigment visible through the sides of the carapace. Like female M. volans, the appearance of female M. elephans may be associated with cryptic mimicry of leaf scars (Otto & Hill 2014, Figure 20), suggesting a similar microhabitat preference.

Figure 8. Positions assumed during the fan dance by a male (♂ #1) Maratus elephans facing a female. 1, The fringe of white scales beneath the tibia adds to the apparent width of the fan when raised to a near-vertical position. 8, The fan is normally fully erect and expanded during the fan dance, but may be partially folded near the beginning or end of this display.
