Discussion: This species was well defined in Kelton’s (1978) excellent paper on Canadian Anthocoridae. This species is closely related to D. reuteri and unicolor because of their left paramere of hammer-type, but differs from them by being almost straight, i. e. not so curved, and by their coloration (reddish-brown) and measurements.
