Tanaostigmodes albiclavus - female

Tanaostigmodes albiclavus - Female
Florida Canyon, Santa Rita Mountains, Pima County, Arizona, USA
Size: Body Length 2.8 mm.
Reared from gall on Mimosa biuncifera.
Gall collected 3-31-18. Adult emerged 4-22-18.
Identification made from description in, New World Tanaostigmatidae by John LaSalle, Contributions of the American Entomological Institute V. 23, No. 1, 1987.

These are primarily gall-formers on various woody trees and shrubs, especially shrubby legumes such as Acacia, Mimosa, Pithecellobium, and Prosopis.

In the U.S., tanaostigmatids are found only in the southwestern deserts and southern Florida. They are not particularly common, but can be collected by sweeping shrubs (particularly woody legumes in flower) or by collecting the galls from the plants and rearing out the adults as you have done.
