Mezira vanduzeei
Usinger, 1936
Mezira vanduzeei is a of flat bug in the Aradidae, described by Usinger in 1936. The species belongs to a family of true bugs known for their extremely flattened bodies, an for living in narrow spaces under bark and in decaying wood. Like other aradids, this species likely feeds on fungal in its concealed microhabitats. Records indicate presence in North America, though detailed biological information remains sparse.
