These features separate Phycusinae from the more diverse Therevinae and other therevid subfamilies.
Habitat
Arid and semi-arid environments, including savannas, scrublands, and dry open woodlands. Associated with sandy or well-drained soils where larval development occurs.
Distribution
Old World tropics and subtropics, with primary diversity in Africa and extending into parts of Asia. The has a more restricted geographic range compared to the Therevinae.
Ecological Role
Larvae are predatory in soil , contributing to the regulation of soil . may serve as minor in arid .
