brigalowae species group
Diagnosis. Members of the brigalowae species group have at least some elytral interstices with several setae across between puncture rows which, in some species (e.g., A. monteithi sp. nov.), results in the elytra appearing vested with a thick setal mat of short hairs; most elytral striae reaching apices.
Remarks. Groupings based on elytral fascia shape (rounded or square at suture) and pronotal form (laterally rounded or angulate) did not correlate with tegminal characteristics. Further attempts to recognise natural groupings within the brigalowae species group based on morphology were, therefore abandoned.
