Four species groups are distinghished: the Cephalosphaera group: C. maximus (Hardy), C. reductus sp. nov. C, appendiculatus (Cresson), C. acuminatus (Cresson), C. filicerus sp. nov., C. biscaynei (Cresson), C. brevis (Cresson); the aeneus group:C. longistylis sp. nov., C. grootaerti sp. nov., C. pallidivittipes sp. nov., and C. furnaceus sp. nov.; the semifumosus group: C. mainensis (Cresson), C. varius (Cresson), C. longiductulis sp. nov., C. curvarmatus sp. nov., C. pallipes (Johnson), C. digitatus sp. nov., and C. hardyi sp. nov. The vestitus group: containing banksi (Aczel), griseus sp. nov., floridae sp. nov., and parafloridae sp. nov. is considered as a separate genus: MICROCEPHALOPS gen. nov. (M. banksi) (Aczel, 1940) comb. nov. (Pipunculus banksi), in order to ensure monophyly of the genus group Cephalops-Beckerias-Wittella. C. eronis (Curran) is considered to be synonymous with C. appendiculatus (Cresson). This species, formerly placed in Parapipunctulus Rafael, is found to be a true Cephalops sp. and has to be replaced in this genus. The geographic distribution of all species is given, and their phylogenetic relationship to the West-Palaearctic Cephalops spp. is discussed.10aCephalops cu10aCephalops filicerus new species10aCephalops furnaceus new species10aCephalops grootaerti new species10aCephalops longiductulis new species10aCephalops longistylis new species10aCephalops pallidivittipes new species10aCephalops reductus new species1 aDe Meyer, M.  uhttps://pipunculidae.myspecies.info/content/systematics-nearctic-species-genus-cephalops-fall%C3%A9n-diptera-pipunculidae
