OnysiusBroun, 1886, is transferred from the endemic New Zealand Chalcodryidae to Promecheilidae, reducing the number of genera of the former to two (Chalcodrya and Philpottia). Onysius shares several adult characters with Promecheilidae, including the abdominal ventrites 3 and 4 not connate and the tegmen subdivided into a basale and apicale (larvae are unknown). A key to the world genera of Promecheilidae is included.
