The genus comprises approximately twelve worldwide, including the notable D. elegans, which has been studied for its potential against scale insects. Species in this genus are endoparasitoids, developing within their . The genus was established by Silvestri in 1915 and has been the subject of recent research on venom biochemistry and viral associations.
