Etymology. The specific epithet refers to the yellow-brown colouration of parts of the carapace ( mellosa, Latin , of honey, honey-coloured) ( Brown 1956).

Diagnosis. Males of A. mellosa differ from all other named species of the genus by the colouration of the carapace which is overall light yellowish-brown with the cephalic region honey-coloured to very dark reddish-brown ( Fig. 10 View FIGURES 10 – 20 ). Females also have a somewhat darker cephalic region but the colour difference between the cephalic and thoracic regions is much less pronounced ( Fig. 21 View FIGURES 21 – 24 ). Tibia I of males has a large spur and megaspine located medially, and metatarsus I is incrassate with the ‘heel’ of the thickening about half-way; this conformation most closely resembles A. pallida from eastern Queensland from which it differs by the less pronounced metatarsal process and the smaller tibial spur and megaspine. Female genitalia resemble those of A. longitheca Raven, 1984 from central Queensland in possessing long lateral tubes ( Figs 23, 24 View FIGURES 21 – 24 ), but they differ in the shape of the median spermathecae which are coiled in A. longitheca and S-shaped in A. mellosa . See Remarks for further clarification.

Genitalia: median spermathecal stalks S-shaped, spermathecae slightly wider than spermathecal stalks; separate straight and elongated tube accompanies spermatheca ( Figs 23, 24 View FIGURES 21 – 24 ).

Pedipalp: length of femur 3.6, patella 2.3, tibia 2.5, tarsus 2.7. Femur without spine, patella with 2 prolateral spines; tibia with 11–13 irregularly placed spines in mainly apical half (not dorsal); tarsus with scopulae ventrally and 2 baso-ventral spines and curved terminal claw.

Legs: femur I with 1 dorsal spines proximally and 1 disto-prolateral spine, patella with 2 (left leg 1) prolateral spine, tibia with a row of three ventral spines (5 on right leg of which 2 are paired) and 2 disto-ventral spines, metatarsi 1 basal and 1 apical pair of ventral spines (left leg) (3 additional medio-ventral spines on left leg). 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. Tarsi, metatarsi and tibiae with numerous dorsal trichobothria of variable length. Paired tarsal claws of legs with two rows of 10–13 (legs I–II) or 5–7 (legs III–IV) teeth each; third tarsal claw reduced and very small.

Leg measurements: length of legs IV>I>II>III. leg I: femur 6.0, patella 3.1, tibia 4.0, metatarsus 3.5, tarsus 2.3, total = 18.9. Dorsal proximal width of patella I = 1.0, tibial index = 0.14, leg I formula = 2.12. Leg II: femur 5.0, patella 3.0, tibia 3.3, metatarsus 3.1, tarsus 2.1, total = 16.5. Dorsal proximal width of patella II = 0.9, tibial index = 0.14; leg II formula = 1.85. Leg III: femur 4.0, patella 2.5, tibia 2.0, metatarsus 2.9, tarsus 1.7, total = 13.1. Dorsal proximal width of patella III = 1.1, tibial index = 0.24; leg III formula = 1.47. Leg IV: femur 5.5, patella 3.2, tibia 4.0, metatarsus 4.4, tarsus 2.2, total = 19.3. Dorsal proximal width of patella IV = 1.1, tibial index = 0.15; leg III formula = 2.17.

Variation: total length 19.3–25.0, carapace 5.4–6.6 long, 6.6–8.7 wide (n = 8).

Distribution. Aname mellosa has been found throughout the central Pilbara, from Jimblebar minesite near the township of Newman in the east to Mount Minnie in the west, and south into the Midwest region of Western Australia ( Fig. 5 View FIGURES 5 – 8 ).

Remarks. Care must be taken when identifying A. mellosa as a number of undescribed species from northern Western Australia have a very similar somatic appearance, but have a different genital morphology. The embolus of male A. mellosa is long and slightly curved, but it is often much shorter and/or much more curved in the undescribed species. An unambiguous identification of females or juveniles in this group is currently not possible, however, we have listed females and juveniles when they have been collected with or in close proximity to males. As stated in the Diagnosis, females of A. mellosa have an unusual genital morphology with long, straight lateral tubes in addition to the median pair of spermathecae. This morphology is similar to that of A. longitheca ( Raven 1985a) , but both species differ in the shape of the median spermathecae.

All records of mature males were collected between January and early June suggesting this species to be reproductively active towards the end of the wet season. Many mature males of A. mellosa were removed from their burrows (R. Teale, pers. comm.) where it is likely that they had matured and were waiting for suitable conditions to emerge and search for adult females. The silk-lined open burrow of A. mellosa is dug at an angle into the substrate and lacks a lid ( Figs 2–4 View FIGURES 1 – 4 ) (R. Teale, pers. comm.).
