Cicadulini
Van Duzee, 1892
Cicadulini is a tribe of within the Deltocephalinae, comprising 15 and over 120 described . The tribe is characterized by through male calling signals, as documented in genera such as Taurotettix. Species within Cicadulini occur across diverse regions including Central Asia, Siberia, the Russian Far East, Kazakhstan, Mongolia, and parts of Europe. The group has been studied for morphological variation and geographical variability in both form and sound production.

Identification
Members of Cicadulini can be distinguished from other Deltocephalinae tribes by genitalic and, in some , characteristic acoustic signals produced by males. The tribe includes the genus Taurotettix, which contains two subgenera (Taurotettix and Callistrophia) with distinctive morphological features.

Distribution
Cicadulini has a broad distribution across the Palearctic, with documented occurrences in Central Asia, Siberia, the Russian Far East, Kazakhstan, Mongolia, the Altai Mountains, Inner Tien Shan, and the European part of Russia.
Behavior
Males of at least some (e.g., Taurotettix) produce -specific calling signals for . Geographical variability in both and acoustic signals has been observed within the genus Taurotettix.
More Details
Taxonomic composition
The tribe contains 15 described and over 120 , though individual genus-level diversity varies considerably.
Acoustic research
Oscillograms of male calling signals have been published for Taurotettix (T.) beckeri, T. (C.) modesta, and T. (C.) elegans elegans, providing a basis for identification and studies of speciation patterns.
