text: # Cychrus
  
  Cychrus Fabricius, 1794 è un genere di coleottero Carabide della sottofamiglia dei Carabinae Osservato nelle ecozone neartica e paleaartica, il genere è caratterizzato dalla morfologia singolare dovuta alla selezione naturale nell'adattamento ad un regime alimentare elicofago.
  
  Alcune delle specie alle quali appartiene sono presenti in Italia, tra le quali le endemiche Cychrus italicus Bonelli, 1810, cicro cilindricolle (Cychrus cylindricollis Pini, 1871) e la sottospecie Cychrus attenuatus latialis endemica dell'Appennino centro-meridionale.
