Figures 76-79

Trissolcus parma Johnson, 1985a: 110, 111 (original description, keyed); Sarazin 1986: 981 (type information).

Diagnosis.

Trissolcus parma may be distinguished from T. ruidus by the lack of rugulae outside of the antennal scrobe and the lack of longitudinal elements in the sculpture of the posterior portion of the mesoscutum. It may be separated from the other members of the Trissolcus thyantae group by the presence of microsculpture on the mesoscutellum.
