Melizoderidae Deitz and Dietrich, 1993
The smallest family of treehoppers is Melizoderidae, known only from Chile and Argentina. This group includes only two genera— Melizoderes and Llanquihuea—both belonging to the subfamily Melizoderinae and tribe Melizoderini. The monophyly of this family is supported by a unique derivation in the nymphs: tergum IX completely conceals the anal orifice dorsally (Deitz and Dietrich 1993a).
Frontoclypeus strongly convex, produced anteroventrally. Distance from eye to base of forewing less than half eye width. Pronotum weakly to strongly produced anterodorsally, not extending posteriorly over scutellum. Scutellum fully visible, convex basally, keeled posteriorly, not elongate. Forewings with veins R, M and Cu diverging from one point or M briefly united with R or Cu. Prothoracic trochanter and femur not fused. Male abdominal segment IX without lateral lobes and lateral plates. Female pygofer not strongly produced posteroventrally. Nymph with abdominal segment IX with ventromedial lobes free (Melizoderes) or fused (Llanquihea), anal opening ventral.
This monotypic family includes only the nominotypical subfamily Melizoderinae and tribe Melizoderini.
