Diagnosis

Males of A. inimica can be distinguished from all species for which males are known except A. barrema and A. magnifica sp. nov. by a moderate to large body size (carapace length>4.0 mm), the presence of a copulatory organ with the bulb tapering into a long embolus (embolus length / bulb length>1.5) with a slightly thicker basal section that narrows and curves sharply at about 0.6 of length, a patch of thicker setae proximally of asetose depression, and the absence of a pronounced, sharp heel on metatarsus I (as in pallida -complex species) ( Fig. 67A–Q ). Males of A. inimica can be distinguished from those of A. barrema and A. magnifica by the presence of a short embolus (embolus length / bulb length ~ 1.2; cf.> 1.5) ( Fig. 67L–M ; cf. Figs 64 , 69 ).

Females of A. inimica can be distinguished from all species for which females are known by the presence of spermathecae with two short vesicles (lateral vesicle length / carapace length ~ 0.05) of roughly equal length, with both vesicles being relatively straight and angled laterally ( Fig. 68L ).

Distribution and natural history

Aname inimica has a wide distribution in north-eastern New South Wales, predominantly in the Brigalow Belt South, Nandewar, and New England Tablelands bioregions. It extends from Mandooran north to Moree, and from The Pilliga east to Armidale ( Fig. 10 ). The form of burrows constructed by spiders of this species is unknown, but is likely to be similar to that of other barrema -complex species ( Fig. 10 ).
