The body and legs of this species are a reasonably uniform dark colour but the adult male's body has a distinctive silvery sheen. Not too much is known of its natural history, but the burrow is said to be fitted with an inwards opening door.

The male of this species should be treated as potentially dangerous since the few tests that have been done on its venom suggest it may have a toxicity similar to, if not as potent as, that of funnel-web and mouse spiders.
