TETTIGADINAE Distant, 1905 (syn. Tibicininae)
5 genera north of Mexico.
The 5 genera of Tettigadinae are best separated by wing veination: primarily the shape of the radial cell and the location of its terminal node on the wing.
Platypedia and Neoplatypedia have the radial cell ovate, with the node 2/3 down the length of the wing.
Okanagana has a roughly trapezoidal radial cell and is quickly separated from Clidophleps, which has the cell much wider and oblong.
Okanagodes is very distinct morphologically from the other genera, and while it has a semi-trapezoidal radial cell, it can't be confused with any species of Okanagana except O. pallidula, whose ranges do not overlap.
The subfamily is most speciose in the western US, but Okanagana can be found reaching New Brunswick and two allopatric species are located in the southeast and midwest (O. viridis and O. balli, respectively).
Not allochronic; most emerge in late June to mid July. Occasionally this period extends into August.
