Amer. Ent. Soc., Trans. 7: 254. Male. Holotype data: Nevada (ANSP). Mutilla ferruginosa Dalla Torre, 1897 . Cat. Hym. V. 8 , p. 40. N. name for Agama ferruginea Blake not Mutilla ferruginea Smith. Diagnosis of male. This species has a deeply excised tridentate mandible that has a complete dorsal carina and a vertical apex ( Fig. 22 ), has sternal felt lines that are mere tufts, lacks mesosternal and coxal processes, and the genitalia have a clavate cuspis that has bifid-tipped setae located ventrally towards the apex ( Fig. 56 ). Female. Unknown. Material examined. California, Riverside Co .: Deep Canyon, 2 males , 16.May.1975 , coll. J. Trucker. Distribution. The western Sonoran Desert, Mojave Desert and northern California into Oregon and Washington. Remarks. This species is placed in the S. orestes species-group. Members of this group can be recognized by their deeply emarginate mandibles, the weak sternal felt line and clavate to spatulate cuspis of the genitalia. Sphaeropthalma ferruginea is the only species in this group that has setae on the cuspis that are bifid tipped. All other species have simple setae on the cuspis. Sphaeropthalma militaris is another species in the S. orestes species-group that possibly be collected at Deep Canyon in the future. It would key out to couple 25 and could be recognized by the rows of inner directed setae present on toward the apices of the parameres of the genitalia (see Fig. 25 in Pitts et al . 2009).
