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.

Fig. 1. Phylogeny and general map of eastern Australian Aname L. Koch, 1873. Left: IQ-TREE Maximum Likelihood phylogeny for the genus Aname with species groups sensu Rix et al. (2021) highlighted in grey, species complexes as defined in this study highlighted in colour, and showing the phylogenetic position of many of the species described herein, as well as some potential species (those with nicknames in quotation marks) that may turn out to be distinct, but did not meet our standards for description. Species groups that are not represented in eastern Australia are collapsed. Support values on the phylogeny show the results of 1000 ultrafast bootstrap replicates, and are only shown in cases where support was below 90%. Top-right: a map of subtropical and tropical eastern Australia, showing the locality of all Aname specimens included in this study. Bottom-right: a smaller phylogeny highlighting the higher-level relationships between species groups of Aname as recovered in this study.
