Diagnosis

Males of A. magnifica sp. nov. can be distinguished from all species for which males are known except A. barrema and A. inimica 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. 69A–Q View Fig ). Males of A. magnifica can be distinguished from those of A. inimica by the presence of a longer embolus (embolus length / bulb length>1.5; cf. ~ 1.2) ( Fig. 69L– M View Fig ; cf. Fig. 67 View Fig ). Males of A. magnifica can be distinguished from those of A. barrema by the presence of a shorter asetose depression on the palp tibia (depression length / tibia length ~ 0.6; cf. ~ 0.7 in A. barrema ) and a thicker metatarsus I (metatarsus I length / width ~ 3.5; cf. ~ 4.5 in A. barrema ) ( Fig. 69K, Q View Fig ; cf. Fig. 64 View Fig ).

Females of A. magnifica sp. nov. can be distinguished from all species for which females are known except A. barrema and A. distincta by the presence of spermathecae with two vesicles, with relatively long and straight lateral vesicles (lateral vesicle length/ genitalia width>0.25) that don’t curve medially at their ends, and very short, straight medial vesicles (medial vesicle length / lateral vesicle length <0.5) ( Fig. 70D, L View Fig ). Females of A. magnifica can be distinguished from those of A. barrema and A. distincta by the presence of larger posterior sigilla on the sternum (posterior sigilla length /sternum length ~ 0.18; cf. ~ 0.14) and spermathecae with triangular lateral vesicles with wide bases tapering to narrow ends ( Fig. 70G–H, L View Fig ; cf. Figs 65–66 View Fig View Fig ).

Etymology

The specific epithet ‘ magnifica ’ is an adjective derived from the Latin ‘ magnificus ’, meaning ‘great, grand’, or ‘magnificent’, in reference to the large and relatively robust nature of this species.

Distribution and natural history

Aname magnifica sp. nov. occurs in north-eastern New South Wales, in the Nandewar and New England Tablelands bioregions, where it is known from four locations extending from Gurley in the east to Inverell in the west ( Fig. 10 View Fig ). 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 View Fig ).
