Comments

Van Achterberg (1990) stated in his diagnosis of Phanerotoma the presence of three distinctive clypeal teeth, although the number of teeth varies between two and three (Zettel 1990c). However, for Australia only a minority of species have three clypeal teeth, and belong to a species group including P. behriae, P. lutea sp. nov., P. novaguineensis and P. paci fi ca which have a reduced r vein and a much longer 3- SR vein.

The subgenus Bracotritoma was discussed by van Achterberg (1990), and a detailed key was provided to distinguish it from the subgenus Phanerotoma; however, Bracotritoma was later treated as a junior synonym by Zettel (1990c). The Australian Phanerotoma fauna consists of species which are not easily recognised as belonging to either subgenus, and thus we follow Zettel ’ s broader definition of the genus here.

Key to Phanerotoma from the Australian arid zone
