Abstract
The state of taxonomy of Idris, egg parasitoids of spiders, in Nearctic North America is reviewed. The concept of Idris is discussed and Ceralobaeus Ashmead is considered a junior synonym (new synonymy). The melleus-group of Idris is defined and 11 Nearctic species are keyed and described: I. castaneus sp.nov. (south and southeastern USA), I. chrysion sp.nov. (southeastern USA), I. costatus sp.nov. (eastern USA), I. lacunatus (Baja California, Mexico). I. leedsi sp.nov. (midsouthem USA), I. melleus (Ashrnead) (south and southeastern USA and southern Canada), I. onychion sp.nov. (southeastern USA), I. ornatus sp.nov. (eastern USA), I. pulvinus sp.nov. (south and southeastern USA), I. spartinae sp.nov. (southeastern USA), and I. triticola sp.nov. (midwestern USA). Extra-limital Nearctic members of the melleus-group are briefly discussed.Keywords
