attenuatus group

C. attenuatus (Fabricius, 1792)

C. semigranosus Palliardi, 1825

Cychrus attenuatus includes two subspecies: attenuatus attenuatus and attenuatus latialis Luigioni, 1922; the high-Alpine species of the cordicollis group probably differentiated from this group. Cychrus semigranosus includes five subspecies (in the sense of Cavazzuti 2010): semigranosus semigranosus Palliardi, 1825 , semigranosus balcanicus Hopffgarten, 1881 , semigranosus montenegrinus Apfelbeck, 1904 , semigranosus albanicus Hoppe, 1929 and semigranosus pindicus Mařan, 1940 . In the key, the morphological characteristics of the larvae of the nominal ssp. of C. attenuatus are considered valid for the species as a whole. The same applies to the morphological characteristics of the larvae of C. semigranosus ssp. pindicus .
