There is only one described genus of Kinnaridae north of Mexico.  They resemble small cixiids (perhaps especially Oecleus) with the vertex of the head narrow and trough-like; frons very narrow near top of head, widening toward frontoclypeal suture with a median ocellus (just above frontoclypeal suture, a feature shared with Cixiidae but no other planthoppers north of Mexico).  Unlike Cixiidae, females have the ovipositor ‘reduced’ instead of strongly projecting and ‘orthopteroid’.  The hallmark feature of the family is that abdominal tergites 7-9 are ‘chevron-shaped’.
