Identifying features

The identity of this spider remains somewhat in doubt because the known range of Aname inimica extends from South-east Queensland only down to about Armidale whereas the spider shown on this page was collected West of Sydney near Orange. However, the visible characters of this male are a better match for those of the few other described Aname species that are listed as being present in NSW and are very similar to those originally stated for Aname inimica.

Females of this species are not readily distinguished from those of other Aname species but the adult males do have some diagnostically useful characters, notably a distinctively shaped tibial megaspine and metatarsus (the next segment of the leg) on Leg I. The sperm delivery tube on the tarsal bulb of the male is relatively short and appears hooked. In addition, the oval shape of the posterior sternal sigilla is said to be unique to A. inimica.

Females of this species spend their entire lives in a burrow but adult males may be collected in late spring or early summer, at which time wet weather induces them to wander above ground in search of burrows containing females of the same species. Like funnel-web males, adult males sometimes blunder into houses. The inimica name was assigned because at least one spider enthusiast was bitten by a male of this species, but no serious or long-lasting effects resulted from this bite.
