Remarks

See the key to complexes and Figures 3–5 View Fig View Fig View Fig for diagnostic information. In life, spiders of the eddieorum - complex vary from honey-tan to dark brown in colour, with the anterior legs often slightly darker than the posterior legs ( Fig. 7 View Fig ); however, colour can vary a surprising amount within species (see, for example, the two female A. briggsi sp. nov. specimens pictured in Fig. 7 View Fig ). Females of the eddieorum - complex generally have reflective bronze setae on the carapace, and sometimes the dorsal abdomen and femora. Males of at least some species have a dense covering of reflective silver setae on the carapace and dorsal abdomen ( Fig. 7 View Fig ). Spiders of this complex generally make an open, silk-lined burrow without silk outside of the entrance, with the entrance often on an angle, and with a hidden secondary ‘wishbone’ entrance. The burrows are often found in areas with a leaf-litter layer, and indeed the entrance may be somewhat embedded in the leaf-litter ( Fig. 7 View Fig ).

Distribution

The eddieorum -complex has a largely inland distribution in Queensland and northern New South Wales, occurring from the Darling Riverine Plains, Brigalow Belt South, and New England Tablelands bioregions, north to the Brigalow Belt North, Mitchell Grass Downs and Desert Uplands bioregions in north Queensland (near the border with the Einsleigh Uplands) ( Fig. 7 View Fig ). They are generally found on or west of the Great Dividing Range, except A. aurensis sp. nov. which extends to near the coast around Townsville and Ayr. The two most southerly species, A. mulgana sp. nov. and A. eddieorum sp. nov., are both widespread; however, in central Queensland many species occur, each with seemingly relatively small ranges. This may be due to the increased topological complexity in this region, and the adjoining boundaries between several different bioregions.

Composition

The eddieorum -complex includes nine described species: Aname aurensis sp. nov., A. briggsi sp. nov., A. dingo sp. nov., A. eddieorum sp. nov., A. hughenden sp. nov., A. longitheca Raven, 1985 , A. mulgana sp. nov., A. rupicola sp. nov., and A. warrego sp. nov.. Based on the drawings of Hogg (1902), A. diversicolor likely also belongs to the eddieorum -complex; however, this species is not treated in this revision as the type specimen is lost, and we were not able to resample at the type locality. Two other potentially distinct species are shown in the phylogeny ( Fig. 1 View Fig ) and on the map for this complex ( Fig. 7 View Fig ), A. sp. “marlong”, and A. sp. “emerald”; however, further evidence is required to confirm that these species are distinct from others known from the area.
