Diagnosis.

Trissolcus cosmopeplae may be distinguished from other species that have sublateral setae and a narrow gena ( T. erugatus , T. hullensis , T. radix , T. solocis , and T. zakotos ) by the presence of extensive rugulae on T2 and the mesoscutellum without macrosculpture. This is also the only New World species outside the Trissolcus thyantae and Trissolcus flavipes groups in which notauli may be visible. All other species with sublateral setae and a narrow gena usually have the posterior region of the mesoscutum longitudinally rugulose and the notauli, if present, are thus obscured.
