The correct scientific name for the above spider is uncertain. The male specimen in the main photo above was found in Victoria and since the same species occurs widely along Eastern Australia it seems likely to be the one listed in the World Spider Catalog as Cycloctenus flaviceps. However, it has recently been suggested it may actually be a Cyclocrassus species, although the world Spider Catalog in April 2017 does not recognize this generic name.

The male of this species is more commonly noticed by the general public because of the black brushes on its legs and its tendency to appear inside houses. The female images also included on this page are now being claimed to be of the same species but if this is so there are great differences in appearance between the two sexes and the male only adopts its adult characteristics after the final moult that leads to the mature state.

Spider(s) with a very similar appearance: None.
