Females
1. Front tarsis without a comb, the second segment with or without some minute spines on the outer side and with the usual apical ones................................................................................................2
-. Front tarsis with a comb of short to fairly long spines, the second segment with a spine on the outer side near the middle which is as long as the apex of this segment......................................................................3
2. Claws dentate (except in A. ithaca, in this species the inner claws of each pair longer than the outer claws, in any case the inner ray acute); three SMCs present.............................................................. Anoplius Dufour
-. Claws bifid, the inner ray truncate, inner and outer claws of each pair the same size; two SMCs present Cameronoplius Evans
3. Claws bifid, the inner ray truncate, inner and outer claws of each pair the same size.................. Dicranoplius Haupt
-. Claws dentate........................................................................................4
4. Anterior margin of clypeus with a distinct median emargination; posterior margin of pronotum arcuate; head and mesosoma with abundant erect hairs......................................................... Lophopompilus Radoskowski
-. Anterior margin of clypeus without emargination, or, if so, either the posterior margin of pronotum angulate or the propodeum only weakly setose or setae absent........................................................................5
5. Marginal cell long, removed from wing tip by not more than its own length, the Rs rather evenly arched; SMC3 wider on Rs than second; spines of tarsal comb very short.................................................. Anopliodes Banks
-. Marginal cell of variable length, Rs always somewhat angled at 3rs-m vein; SMC3 narrower on the Rs than the second.....5
6. Apical margin of clypeus with a median emargination; front narrow, MID no over 0.56× TFD.......... Notiochares Banks
-. Apical margin of clypeus truncate, or, if emargination, the front broader than above........... Arachnophroctonus Howard
Males
1. SGP with a large plumose process at its base which projects from the emargination of the preceding sternite............................................................................................ Lophopompilus Radoskowski
-. SGP without a basal plumose process...................................................................... 2
2. S4 with a semicircular area of felt-like pubescence along its posterior margin; SGP with a V-Shaped emargination................................................................................................ Notiochares Banks
-. S4 without such an area of felt-like pubescence; SGP not as above...............................................3
3. Last segment of tarsus unmodified, the sides nearly parallel, not at all produced laterally.............................4
-. Last segment of tarsus modified, the inner side weakly to strongly produced laterally................................5
4. SMC3 wide above, wider than the second; parapenial lobes not spatulate apically; posterior face of propodeum sometimes with dense short setae........................................................................ Anopliodes Banks
-. SMC3 narrower above than the second; parapenial lobes spatulate apically; posterior face of propodeum with dense elongate flattened setae......................................................................... Dicranoplius Haupt
5. Propodeum in profile sloping evenly from front to rear; venter often with dense brush of setae............ Anoplius Dufour
-. Propodeum in profile sloping weakly in front and much more abruptly declivous on the posterior fourth; venter with dense brush of setae in few species.............................................................................6
6. Two SMCs present, 2SMC receiving both 1m-cu and 2m-cu; fore wing with the transverse M+CuA and cu-a interstitial........................................................................................ Cameronoplius Evans
-. Three SMCs present............................................................. Arachnophroctonus Howard
