Trissolcus hullensis (Harrington)

Remarks.

The identification of Trissolcus hullensis is straightforward using the characters presented in Johnson (1985) and repeated in Talamas et al. (2015). Characters of the posterior mesosoma are particularly useful for determining this species: In T. hullensis the propodeum and metanotum are directly adjacent between the metapostnotum and metascutellum (Fig. 4), whereas in other species of Nearctic Trissolcus, the metapostnotum extends medially toward the metascutellum, and separates the propodeum from the metanotum (Fig. 5).
