Cicadetta montana s. lat. (Scopoli, 1772)

Notes

General distribution: Northwest Europe: Denmark, Estonia, Finland, Lithuania, Luxembourg, Norway, Sweden; Southern Europe: Bulgaria, Croatia, France, Greece, Italy (including Sicily), Montenegro, North Macedonia, Romania, Slovenia, Serbia, Spain; Central Europe: Austria, Belgium, Czech Republic, Germany, Hungary, Netherlands, Poland, Slovakia, Switzerland; British Isles: United Kingdom; Eastern Europe: Moldavia, Russia, Ukraine; Middle East: Iran, Palestine, Turkey; Transcaucasia: Azerbaijan, Georgia, Russia (Dagestan); Central Asia: Kazakhstan, Kyrgyzstan, Russia (Bashkiria, Chuvashia), Tajikistan; Siberia: Russia (Southern Siberia); Eastern Asia: China (Heilongjiang, Sichuan), Korea, Russia (Primorsky Krai, Sakhalin) (summarised by Nast 1972, Kudryasheva 1979, Duffels and van der Laan 1985 and Sanborn 2014).

Distribution in Bulgaria: In addition to a single literature citation by Yoakimov (1909), the specimens of Cicadetta montana s. lat. were found in the BFUS, SOFM and ZISB collections (Fig. 32 ). With the exception of some specimens of Cicadetta macedonica , we could not determine the majority at the specific level only on the basis of morphological characteristics. Additionally, the altitudinal distribution (Fig. 33 ) of this material with three peaks between sea level and 200 m a.s.l., 400 and 600 m a.s.l. and 1000 and 1200 m a.s.l., shows that within the material in the collections, there is most probably more than one species.

Diagnosis

Singing activity is a very important mechanism used by male cicadas to attract females and is therefore species-specific (e.g. Gogala & Trilar 2004). Recent bioacoustic studies have shown that Cicadetta montana (Scopoli 1772), once thought to be a single widespread Palearctic cicada species, is, in fact, a complex of morphologically-similar sister species that are best characterised by their song patterns. With the help of bioacoustic methods, we find four species from this complex in Bulgaria: Cicadetta montana s. str. (Scopoli, 1772), Cicadetta brevipennis Fieber, 1876, Cicadetta cantilatrix Sueur and Puissant, 2007 and Cicadetta macedonica Schedl, 1999.
