The Thyreocoridae are a family of shield bugs, known by common names that include negro bugs or ebony bugs.[1] Historically, a few authors have called this family "Corimelaenidae" (e.g.[2][3]), but the name Thyreocoridae, published in 1843, has nomenclatural priority over Corimelaenidae, published in 1872.[4][5][6] Other classifications have placed them as a subfamily within the broad family Cydnidae.[7]
