North American Kinnaridae
Kinnaridae is a small group of mostly tropical species, consisting of 21 genera and 104 species (Bourgoin 2012). The higher classification was most recently addressed by Emeljanov (1985, 2006), who defined Oeclidiini for the three New World kinnarid genera Oeclidius, Southia and Micrixia (the recently described Kinnapotiguara troglobia probably belongs to this tribe). Kinnaridae is a relatively primitive taxon, derived near the base of the planthopper phylogeny, although fossils are known only since the mid Mesozoic (Bourgoin & Lefebvre 2002, Szwedo et al. 2004, Urban & Cryan 2007).
Kinnaridae is represented in America north of Mexico by 5 species in the genus Oeclidius found entirely in the southwest, with 18 additional Oeclidius species found in Central America (1 of these reported from South America)
Kinnarids are similar to small Cixiidae in general appearance, and they share the row of spines on the second segment of the hind tarsomere and may have a median ocellus near the frontoclypeal suture. Unlike cixiids, females have a reduced ovipositor and abdominal tergites 7-9 are “chevron-shaped” wax-producing plates. Oeclidius was revised by Ball (1934).
There appear to be undescribed Kinnaridae from the south west, and there are many undescribed species in the tropics.
The nymphal habits and host biology of Kinnaridae are largely unknown. There are few host records (most of these on Asteraceae or Lamiaceae), with most species reported as monophagous (Wilson et al. 1994). Nymphs are evidently subterranean, with adults found on above-ground portions of plants, although adults have also been found on roots (Fennah, 1980, Wilson et al. 1994).
