We describe the cicada Okanagana georgi, sp. n. along with notes on its biology and acoustic behavior. The species is restricted along Schnebly Hill Road in Coconino County, AZ. It is associated with Arizona cypress, Cupressus arizonica Greene, in the riparian habitat of the canyon. The species is most active in the late morning and late afternoon. The song is a continuous train of pulses produced at a rate of 106.92 Hz and an intensity of 97.4 dB. Thermal responses (minimum flight temperature 19.76°C, maximum voluntary tolerance temperature 33.13°C, heat torpor 43.00°C) are related to the habitat and observed behavior. A key is provided to the species of Okanagana Distant found in Arizona.
