Overview
McKamey 2023a published an updated key to all 8 genera (3 new) of the tribe based on features of the forewing venation and the pronotum. That work also gives an historical overview of tribe. As noted below, McKamey and Wallner (2022b) described and illustrated the nymphs of Acutalis, Bordoniana, and Thrasymedes, and provided a key to the 5th instars of these genera.

Diagnostic characters
Pronotum simple or with suprahumeral horns; posterior process not concealing forewing in repose. Forewing with veins R, M, and Cu separate near base; R2+3 present as distinct branch of R; with or without s crossvein; with 1 or 2 m-cu crossveins. Hind wing with 1 r-m crossvein; marginal vein R2+3 distinct.
Immatures
McKamey and Wallner (2022b) described and illustrated the nymphs of Acutalis, Bordoniana, and Thrasymedes, along with a key to the 5th instars of these genera. The eggs are deposited within stems.
Ecology
Not attended by ants, the nymphs are remarkably cryptic on their host plants (McKamey and Wallner 2022b).
Behavior
The nymphs are solitary (McKamey and Wallner 2022b).
