pompilidae -
Entypus

Size: approximately 25mm
i think this is a battle worn pepsis elegans... taken just after she had paralyzed a rather large Lycosid.

Could be, but...
it could also be a species of
Entypus
. They are large and similar to
Pepsis
. They use only Lycosids as nest provisions. I also think that the all-dark subspecies of
P. elegans
has a little more brilliant blue reflection on the body. (See the thumb below)
Also, if there are tarantulas in Arkansas I suspect that
P. elegans
would prey on them preferentially. I think they facultatively take large spiders of other families only in the east, where tarantulas are absent (which I suspect is why they are the only eastern species of
Pepsis
). If it were from Ohio (or one of the surrounding states) I would automatically call it
E. fulvicornis
, but I think if it is indeed
Entypus
, Arkansas has a couple other species. These species are separable only on characters that can be seen under a scope.

Entypus
i think you are right... i was thinking that the only two with the orange/yellow antennae we had in my area were P. elegans and E. unifasciatus, which i find often enough and with the orange patches on the wing makes it easier to identify... however, the list i found for the possible Arkansas pompilids has three Entypus species for the state, E. unifasciatus, E. fulvicornis, and E. magnus. also, if you were wondering, we do have tarantulas in the state and im pretty sure we have some of the bigger Pepsis species, i saw a monster while hiking a few weeks ago. so, the question is would it be safe to call this Entypus fulvicornis and file it under that?

Too bad...
you guys have
E. magnus
down there (for ID purposes, that is). They are extremely similar to
E. fulvicornis
, in fact they have black wings and yellow antennae and the only way to tell them apart is through things that can only be seen through a scope. I wasn't sure if you had that species, but I thought you might. That's why I didn't call it
E. fulvicornis
right off the bat. In either case it seems that
E. unifasciatus
is the dominant species in that genus in most of the country. In the data I have collected for a survey of the spider wasps of Ohio I have nearly twice as many
E. unifasciatus
as
E. fulvicornis
(Ohio's only two species, by the way). I'd put this image on the
Entypus
genus page.
