Diagnosis.

Trissolcus utahensis is a relatively dark-colored species, though some specimens from the southern part of its range have lighter-colored appendages. In the Nearctic region it is most similar to T. basalis . The two may be distinguished by the color of A1, usually dark, concolorous with the radicle in T. utahensis, and yellow, sharply contrasting with the dark radicle in T. basalis; and the mesoscutellar sculpture, smooth in T. utahensis, coriaceous in T. basalis .
