Trissolcus occiduus Johnson, 1985a: 109, 111 (original description, keyed).

Diagnosis.

This species may be distinguished from other species in the Trissolcus thyantae group by the expanded gena. It may also be separated from T. thyantae by the complete mesopleural carina, and from T. parma and T. ruidus by the entirely smooth mesoscutellum and absence of a genal carina.
