Cnephia
Enderlein, 1921
black flies
Cnephia is a of nine black fly (Diptera: Simuliidae) described by Enderlein in 1921. The genus exhibits a disjunct Northern Hemisphere distribution spanning Eastern Europe to Siberia and North America. Two species, C. dacotensis and C. ornithophilia, have been subjects of cytogenetic research due to their unusual systems that interact with nucleolar organizer expression and larval development rates.
