Dexiinae is a of (: ) comprising approximately 15 tribes and over 500 described . Members are , with developing inside . The subfamily has a distribution and includes notable such as Dexia, Rutilia, and Voria. Australasian Dexiini have been shown to parasitize scarabaeid larvae (soil-dwelling) and beetle larvae (wood-dwelling), with host associations correlating to morphological traits.
