Key to females of Australian Baeus View in CoL spp.
Please note, because of the small size of the specimens to be identified, the minimum magnification required to view the characters used in this key is 80x's. In addition, an eyepiece graticule is required because measurements of various characters and their states are relied upon in this key.
