Comments: The type locality is in the vicinity of Kharkiv (Charkov), Ukraine. Widespread and common: Albania, Algeria, Armenia, Azerbaijan, Czech Republic, Egypt, France, Georgia, Hungary, Italy, Poland, Romania, Russia (east through Siberia and into the arctic circle), Serbia, Spain, Tunisia, Turkey, Ukraine, Uzbekistan; “Central Sahara” ( Thiele 1900; Gurney 1909; Daday 1913b 1914; Gauthier 1938; Cottarelli 1971; Šrámek-Hušek et al. 1962; Vekhov 1974; Lebedeva 1982; Stoicescu 2004). Type species of the genus by monotypy ( Mattox 1957b). Joly (1842) and Alonso (1996) provide excellent drawings. Daday (1914) states that C. sibericus is intermediate among several other taxa that were subsequently treated as synonyms of C. tetracerus . Daday (1914) reported C. simoni only from one locality in Lebanon (Beirut), but that it was very similar to C. tetracerus . Cyzicus ornatus was reported from Siberia. Cyzicus variabilis was redescribed by Stoicescu (2004) and presented as a valid species. However, it should be re-examined using modern standards.
