Abstract

A female of Oobius depressus (Girault) (Hymenoptera: Encyrtidae), collected in a modified Malaise trap in the canopy of a black locust tree, Robinia pseudoacacia, at Rose Lake State Wildlife Area in Bath Charter Township, Clinton Co., Michigan, U.S.A., is re-described and illustrated. This species was previously known only from the type series of headless specimens of both sexes from the type locality in Morristown, Henry Co., Illinois, U.S.A. These type specimens were from a single cohort of locust borer, Megacyllene robiniae (Forster) (Coleoptera: Cerambycidae), eggs collected and reared over one hundred years ago. An updated taxonomic key to females of native and introduced species of the genus Oobius Trjapitzin, which now includes O. depressus, is provided.
