description: Tibicinini Distant, 1905
Type genus. Tibicina Kolenati, 1857 (type species Cicada haematodes Scopoli, 1763).
Diagnosis (modified from DISTANT 1905 and LEE 2012). Headincluding eyes narrower than the lateral angle of pronotalcollar and narrowerthan mesonotum. Supra-antennal platesnot meeting the eyes laterally (except in Okanagodes Davis, 1919). Pronotum longer than head, generally more or less distinctly narrowed anteriorly. Mesonotum wider than pronotum (not including the pronotal collar). Mesonotal stridulatory apparatus absent. Male operculum not reaching posterior margins of sternite II. Wings hyaline (tinged in yellowish brownin Subtibicina Lee, 2012); base of wings usually reddish or yellowish orange; veins of fore wings fuscousblack (only in Subpsaltria Chen, 1943). Fore wings: somewhat talc-like and obscurely wrinkled, their greatest width always more than one third of their length; marginal area present. Hind wing first cubital cell width at distal end about equal to second cubital cell. Abdomen more or less cylindricaland attenuated posteriorly. Timbal organs present. Uncus usually very prolonged and prominent. Pygofer upper lobes absent. Claspers absent. Theca not laterally expanded or distally ornamented.
Included genera and number of species. Clidophleps Van Duzee, 1915 (8 species); Gibbocicada gen. nov. (1); Okanagana Distant, 1905 (57); Okanagodes Davis, 1919 (3); Paharia Distant, 1905 (6); Subpsaltria Chen, 1943 (1); Subtibicina Lee, 2012 (1); Tibicina Kolenati, 1857 (17); Tibicinoides Distant, 1914 (3).
Distribution. Holarctic, Orientaland Neotropical (Fig. 1).
Key to the genera of Tibicinini
