Remarks
See the key to complexes and Figures 3–5 View Fig View Fig View Fig for diagnostic information. In life, rubrochelicera -complex species are quite light in colour, ranging from pallid to tan-brown, although their chelicerae can be much darker in colour, depending on the species ( Fig. 12 View Fig ). Their burrow is particularly unusual in its absence of a conspicuous silk lining, and usually also the absence of a secondary wishbone entrance ( Fig. 12 View Fig ). However, some specimens have been collected with a secondary entrance, and when present, this consists of a secondary burrow shaft that runs directly adjacent to the main burrow.
Distribution
The rubrochelicera -complex occurs from northern New South Wales, in the Darling Riverine Plains and Brigalow Belt South Bioregions, as far north as the Cape York Peninsula in far north Queensland. They are typically found inland of the Great Dividing Range ( Fig. 12 View Fig ).
Composition
The rubrochelicera -complex includes seven described species: Aname fossoria sp. nov., A. fuscochelicera sp. nov., A. inglewood sp. nov., A. nigrochelicera sp. nov., A. nigrotarsa sp. nov., A. rubrochelicera sp. nov., and A. savannensis sp. nov.
