Diagnosis.

Trissolcus hullensis is most closely related to T. solocis , T. radix and T. zakotos . Trissolcus hullensis may be distinguished from these by the anteriorly invaginated metapostnotum. Additional characters useful for identification are: the paracoxal sulcus in the ventral half of the metapleuron, absent in T. hullensis , present in T. radix and T. zakotos ; sculpture of the mesoscutellum, coriaceous or smooth in southern specimens of T. hullensis , coarsely areolate in T. solocis and T. radix ; the color of the radicle, black in T. hullensis , T. zakotos and T. solocis , yellow in T. radix ; and the rounded vertex, sharply angled in T. radix and T. solocis .
