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

Diagnosis.

Trissolcus ruidus may be separated from T. parma by the presence of rugae on the lateral frons (Fig. 86 ) and longitudinal elements that are often present in the sculpture of the mesoscutum between the notauli. Like T. parma , it may be separated from the other members of the Trissolcus thyantae group by the presence of microsculpture on the mesoscutellum.
