Thyanta

Genus-level diagnosis based on male genitalia. Each paramere F-shaped, with an obtuse protuberance on the shaft usually prominent, apex spinose, and ectal surface convex. Each lateral conjunctival lobe of the aedeagus with a single spinose diverticulum. Anterolateral margins of the pronotum straight to slightly concave, concolorous with the pronotal surface. Spermathecal duct below the proximal flange slightly to greatly swollen and coiled, but never forming a distinct cylindrical structure. The sclerotized rod is somewhat elongate and lacks any subapical swelling. Distal end of the sclerotized rod swollen subapically, narrowed and sometimes elongate distally. Spermathecal bulb globose, usually with relatively large coiling below the proximal flange, sometimes forming a cylindrical structure. Each paramere apically acute, ectal surface convex.
