Distribution. Southern Europe ( France, Italy including Sicily, Slovenia, Croatia, Serbia, Greece including Aegean Islands and Crete, Bulgaria, Romania, Ukraine including Crimea), Turkey, Cyprus, Caucasus ( Armenia, Georgia, Azerbaijan), northern Iraq, western Iran and Levant ( Lebanon, Jordan, Israel and Palestine). The species seems to be absent from the Iberian Peninsula.

Pollen hosts. Oligolectic on Ornithogalum ( Asparagaceae ), e.g. O. narbonense , O. pyramidale , O. pyrenaicum ( Gogala 1999, 2014; Sedivy et al. 2008; Westrich 2010).

Nesting biology. C. mocsaryi nests in insect burrows in dead wood and in hollow stems ( Banaszak & Romasenko 2001; Westrich 2010; Gogala 2014).

Note. C. dolosum sensu Ungricht et al. (2008) was formerly regarded as a species different from C. mocsaryi and is identical with the taxon newly named as C. kurdistanicum sp. nov. in the present publication (see above). The examination of the female lectotype of C. dolosum (Benoist, 1935) revealed that the type is a small individual of C. mocsaryi . In addition, a conspecifity of C. dolosum and C. kurdistanicum can be excluded because the type locality of C. dolosum in northwestern Turkey is far away from the known distribution range of C. kurdistanicum , which extends from southeasternmost Turkey to eastern Iran.
