Figures 94-98

Trissolcus thyantae Ashmead, 1893: 162, 163 (original description, keyed); Brues 1916: 550 (description, keyed); Kieffer 1926: 127, 128 (description, keyed); Masner and Muesebeck 1968: 74 (lectotype designation); Johnson 1985a: 108, 111 (description, keyed).

Diagnosis.

Trissolcus thyantae is most similar to T. occiduus and T. valkyria . It may be separated from T. occiduus by the narrow malar region and from both by the lack of a complete mesopleural carina.
