Zoosys- tematica Rossica, 15(1): 113-130. A key to Mexican species of Coccophagus is given. Five new species from Mexico are described: C. femoralis sp. n., C. lunai sp. n., C. mazatlan sp. n., C. nigrans sp. n. and C. sostenesi sp. n. Diagnosis, host record, distribution and examined material are given for each of the 23 Mexican species. S.N.
