Known range: Occasionally found across Northern Australia from Broome to Cape York and down the east coast to Melbourne, but not recorded in Tasmania, SA or most of southern WA.

Spider(s) with a very similar appearance: Like Cytaea and Euryattus species, Hasarius adansoni has fissident dentition on its chelicerae and the three genera can be difficult to distinguish unless the male or female genitalia of an individual specimen can be examined with a stereo microscope.
