Introduction

Acatopygia is endemic to coastal south-eastern Australia and is frequently found in sandy, heath habitat types. The banded wings, shape of the head, and male genitalia are diagnostic for the genus. The shape of the gonocoxites and aedeagus indicates a close relationship between Acatopygia and Patanothrix (Winterton 2007d).
Acatopygia pulchella is common in southeastern Queensland while A. paradoxa is more common in southern New South Wales. Acatopygia olivacea is less common than the other two species in collections and is known from southern Queensland to Northern New South Wales (Winterton 2007d).
