The Flatinae are a subfamily of planthoppers, erected by Maximilian Spinola in 1839. Genera have been recorded from all continents except Antarctica: especially in tropical and subtropical regions. Description Like all other planthoppers, they suck phloem from plants. The antennae are small and the second segment is longer and ends in a bulge and a flagellum arises from it. They have two ocelli and nymphs have a tail of waxy filaments. Of the two sub-families in the Flatidae, the bodies of adult Flatinae are flattened laterally and the tegmina are tent-like (unlike the Flatoidinae, where the body is not laterally compressed and the tegmina are not as tent-like).
