description: Aname barrema -complex
Figs 1, 3E, 5E, 10, 64–70
Remarks
See the key to complexes and Figures 3–5 for diagnostic information. The few specimens of the barrema -complex that we have seen in life range in colour from tan to dark brown (Fig. 10). A female of A. barrema had striking bronze setation covering its dorsal carapace, chelicerae, abdomen and femora (see Fig. 10). The burrow of this same spider was an open, silk-lined burrow without silk outside of the entrance, with the entrance at an angle, and with a hidden secondary ‘wishbone’ entrance. The burrow was found on relatively flat ground with a leaf-litter layer and was embedded in the leaf litter (Fig. 10).
Distribution
The barrema -complex occurs from northern New South Wales, generally inland of the Great Dividing Range, as far north as Eidsvold in Queensland. This range includes the Brigalow Belt South, New England Tablelands, Nandewar, and Southeast Queensland bioregions (Fig. 10).
Composition
The barrema -complex includes four described species: Aname barrema Raven, 1985, A. distincta (Rainbow, 1914), A. inimica Raven, 1985, and A. magnifica sp. nov.
