Female genitalia with corpus bursae asymmetrical (with the exception of one Australian species), medium-sized to large, membranous, with a small diverticulum, signum in most species present. The ventral surface of the seventh abdominal segment in females is rough, often with a pair of distinct “pockets” or rounded depressions. Habitat. Wet sclerophyll forest to subtropical and tropical primary or secondary forest at low to moderate elevations of 2130 m . Distribution. Indo-Australian region.
