C. californicum vs C. zimmermanni
 C. californicum - The metaplueron which is the narrow segment on the thorax below the hind wing attachment site is clearly depressed well below the rest of the surface of the side of the thorax, this is particularly true in the trough between the two spiracles - In comparison the far sides of the metanotum contain a thin, projecting flange that projects below the segment and into the area of the propodeum a short ways (1)
 C. zimmermanni - The metaplueron, which is the narrow segment on the thorax below the hind wing attachment site, is not or only slightly depressed below the rest of the surface of the side of the thorax, the entire region while showing some ups and downs around the spiracles is essentially the same height at as the surrounding sides of the thorax, particularly the propodeum - In comparison the far sides of the metanotum are relatively uniform, anything that could be mistaken for a projecting flange does not project below the segment into the area of the propodeum (1)
Female vs. Male, AMMOPHILA only

 Male, Head, antennae has 13 segments including pedicel and scape - Abdomen, last segment has CLASPERS, sometimes very small claspers, NO STINGER (27)
Female, P. atratus vs P. canadensis vs P. parkeri vs P. thomae
 P. atratus - Head, long upright hairs on face BLACK colored - Thorax, scutum all BLACK with no tiny gold hairs - Scutellum, BLACK and usually DULL, not shiny or with any tiny gold hairs - Wings completely DARK TINTED, not clear - Abdomen color ALL BLACK to very DARK RED (1)
 P. canadensis - We are unable to find any dependable distinguishing characteristics between P. canadensis and P. parkeri, however, in the East P. canadensis is very uncommon and thus identifying this species should be restricted to males, which have their own problems (1)
 P. parkeri - Other than P. atratus, this is the primary Prionyx species in the East. Specimens of P. canadensis and P. thomae have been identified East of the Mississippi in the past but should be done so only with caution - Compared to P. thomae, the appressed silver and gold hairs on the body are much more restricted, the pronotal lobe with usually only a fringe of appressed silver hairs along its rim, appressed hairs on the mesepisturnum limited to only just above the coxae of the middle legs and on the propodeum just above the hind coxae, often appressed hairs are entirely absent or present as only a very faint shimmer, integument of the rear face of propodeum largely exposed and not hidden by hairs (1)
 P. thomae - This species is readily identified by the fact that the labial palpi are extremely short, usually much less than half the length of the maxilary palpi and most often not visible when the tongue is retracted, in the other species both sets of palpi are about the same length and are usually easily visible even when the tongue is retracted - When directly compared to P. canadensis and P. parkeri this species has greater amounts of appressed silver or slightly gold hairs, the pronotal lobe is usually greater than half covered, the mesepisturnum along the suture with the metepisturnum has appressed hair in a band all the way to just before the most protruding portion of the segment, the rear face of the propodeum is usually almost completely obscured by appressed hairs, but this is a bit more variable, with some specimens showing less - Very uncommon in the East, perhaps restricted only to Florida and the Deep South (1)
