Acutalini
Acutalini is a tribe of treehoppers in the family Membracidae, containing approximately 26 described species distributed from Canada to Brazil and Peru. Members are characterized by distinctive forewing venation including separate R, M, and Cu veins near the wing base, presence of R2+3 as a distinct branch, and R4+5 confluent with M distad of the M fork. Nymphs are cryptic, solitary, and not ant-attended, with unique morphological features including paired scoli on thoracic and abdominal segments. Adults are primarily Neotropical, with many species associated with forest canopy habitats.
Micrutalini
Micrutalini is a tribe of treehoppers (Hemiptera: Membracidae: Smiliinae) containing two genera: Micrutalis and Trachytalis. The tribe is distinguished by exceptionally small fifth-instar nymphs (3.0–3.5 mm) and unique morphological features including ventrolateral scoli in some species—a condition unknown elsewhere in Smiliinae. Nymphs are cryptic, solitary, and not associated with ants. The tribe occurs throughout much of the Americas and the West Indies.
