Sinea anacantha
I cannot really confirm this species for certain from the photograph but it serves as an excellent example in this extremely messy genus. The assassin shown here resembles the paratypes of S. anacantha in the UMMZ in color, cephalic spines and pronotal structure. I can't see the shape of the dorsoapical spine of the profemur which is the key character in anacantha; it is reduced to a mere nub and this is the feature referenced by the species epithet. S. anacantha was also described from Utah. S. diadema or S. confusa are really the only other options and I have reasons to doubt that possibility. Check out the Info page for a more concrete description of this insect.

I don't have any specialized knowledge about this state of the proboscis in either reduviids or heteropterans in general. Possibilities include substrate, disease, parasites, etc. It's interesting because in the Saicinae (Oncerotrachelus and others) one of the subfamily characters is a bulbous rostral segment very similar to what is shown here. In this case though it's certainly a mere coincidence.
