Working list of the Pompilid wasps likely in Arkansas. Obtained from internet sources and the Nearctica North American list as well as Evans three volume Taxonomic studies from the 50's. There are about 300 North American species in 34 genera. This is a much smaller group overall than the related Sphecidae. Not all those listed below are proven for the state. I have 27 genera here and 125 species with three additional subspecies in the Anoplius genus. This is likely slightly generous for our state with 44 of these yet collected. Species with AR in blue have specimens in the U of A Fayetteville collection (72 species). The number of counties for Arkansas is in brackets. County listing is here for the species with over three counties. And someone at the museum in the past must have had connections because virtually every specimen of Pompilid there was determined to species by Howard Ensign Evans.
All species use spiders for their food caches. Almost all are ground nesters with the exception of a few trap nesters in Dipogon and Auplopus. Often the Pompilids are colored with combinations of blacks and oranges. Some are very large. And the sting of the Pompilids is renowned. On the pain scale it exceeds the rating of the stunning Velvet ant sting. A few of these wasps take adult Tarantulas head to head in one of the higher heroic acts in the insect world.
Former genera in this previously confusing group are in parentheses. There are very few images of these wasps on the internet. But any links available are linked to species or genera. States listed are the ones I have from multiple sources and from Howard Ensign Evans' 1950, 3 volume work A Taxonomic Study of the Nearctic Spider Wasps Belonging to the Tribe Pompilini. That work does not cover the whole family so some ranges are still incomplete. Subspecies are included where defined in Evans' papers. Texas only species are not included until they are proven to occur elsewhere in the east. I also have information on the Pepsinae and Ceropalinae from Townes' Smithsonian paper from 1957. I will add a genera key for some Pompilinae to the site when I define one from Evans' papers. It is now here. And a species key for the large genus Anoplius. Clicking on the genus name will take you to any prepared keys to species.
