Etymology. This species is named for Mara Blosfelds, the senior author’s mother.

Diagnosis. Males of A. marae   resemble A. barrema Raven   , 1985, A. distincta Raven   , 1985, A. inimica Raven   , 1985 and A. ellenae   in the shape of the bulb which tapers gradually to the embolus (Figs 50, 51), but differ in the shape of the embolus which is broadly flattened at the base (Fig. 51). In addition, A. marae   males lack the retrolateral patch of short setae on the pedipalpal tibia (Figs 50, 51) that are characteristic for A. ellenae   (Figs 41, 42) and also have fewer maxillary cuspules (<100 in comparison to> 100) which do not extend to the maxillary heel (Fig. 47). Females of A. marae   are unknown.

Description. Adult male (based on holotype WAM T 98424): medium-sized nemesiid spider (total length 13.4).

Colour: carapace reddish-brown with somewhat darker cephalic region (Fig. 43), eye region dark brown (Fig. 46); sternum light brown, darker towards margins, sigilla light brown and labium brown (Fig. 45); abdomen dorsally dark greyish-brown (Fig. 44), ventrally light brown; chelicerae very dark brown; pedipalp segments uniformly brown (Fig. 50); leg I dark reddish-brown with metatarsi and tarsi brown (Fig. 48), legs II-IV brown.

Carapace: 7.2 long, 5.6 wide; eye group (Fig. 46) 1.4 wide, 0.7 long; fovea slightly procurved (Fig. 43).

Sternum and labium: 4.4 long, 2.7 wide; 2 pairs of very indistinct elongated sigilla in posterior half (Fig. 45); labium wider than long, slightly indented anteriorly (Fig. 47).

Maxillae: with <100 pin-like cuspules, not extending to heel (Fig. 47).

Chelicerae: without rastellum, promargin with 11 irregularly sized teeth, retromargin with 3 small teeth proximally.

Abdomen: 6.7 long, 3.7 wide (Fig. 44). Four spinnerets, terminal segment of posterior lateral spinnerets digitiform.

Pedipalp: length of femur 3.8, patella 2.2, tibia 2.5, tarsus 1.7. Femur with 1 disto-prolateral spine, patella with 2 prolateral spines. Tibia with 2 long ventral spines, and 4 disto-prolateral; with distinct disto-ventral depression without setae (accommodates bulb and embolus) (Fig. 50); tarsus terminally blunt (Fig. 51); bulb elongated, globular, tapering into short embolus (Figs 50, 51), embolus ca. 0.8 long, curved and flattened at base, straight and tapering distally (Figs 50, 51).

Legs: femur I with 2 dorsal spines and 2 disto-prolateral spines, patella with 2 prolateral spines, metatarsi and tarsi without spines; tarsi and apical half of metatarsi of leg I and II ventrally with entire dense scopulae, tarsi of legs III and IV with divided very weak scopulae. Tibia I with large spur and megaspine, metatarsi incrassate (Fig. 49). Tarsi, metatarsi and tibiae with numerous dorsal trichobothria of variable length. Paired tarsal claws of legs with two rows of 8-12 teeth each; third tarsal claw reduced and very small.

Leg measurements: length of legs IV>I>II>III. Leg I: femur 5.8, patella 3.5, tibia 4.1, metatarsus 4.2, tarsus 2.5, total = 20.1. Dorsal proximal width of patella I = 1.2, tibial index = 0.16, leg I formula = 2.79. Leg II: femur 5.2, patella 2.8, tibia 3.6, metatarsus 3.8, tarsus 2.3, total = 17.7. Dorsal proximal width of patella II = 0.9, tibial index = 0.14; leg II formula = 2.46. Leg III: femur 4.4, patella 2.5, tibia 2.7, metatarsus 3.6, tarsus 2.1, total = 15.3. Dorsal proximal width of patella III = 1.0, tibial index = 0.19; leg III formula = 2.13. Leg IV: femur 5.8, patella 3.0, tibia 4.2, metatarsus 5.0, tarsus 2.5, total = 20.5. Dorsal proximal width of patella IV = 1.1, tibial index = 0.15; leg III formula = 2.85.

Variation: total length 14.6-18.1, carapace 6.1-7.6 long, 4.7-5.8 wide (n = 10).

Adult female: unknown.

Distribution. Aname marae   has only been found near the township of Tom Price in the central Pilbara region of Western Australia (Fig. 8).

Remarks. As for A. ellenae   (see above), most males of A. marae   were dug from burrows before the beginning of the wet season (in September) and may have waited there for the first seasonal rainfalls before searching for females.
