A CHECKLIST OF THE HERPETOFAUNA FOR THE SIERRA DE SANTA ROSA, GUANAJUATO, RESULTED FROM SIX FIELD TRIPS IN A TWO YEARS PERIOD IS PRESENTED. THE ACTUAL DIVERSITY IS COMPARED WITH THAT REPORTED BY A. DUGES (1869, 1895, 1896) DENOTING THOSE SPECIES CATALOGUED IN THE NORMA OFICIAL MEXICANA (NOM-059-ECOL-1994). THIRTY ONE SPECIES WERE REGISTERED (11 AMPHIBIANS AND 20 REPTILES), SEVEN MORE THAN THOSE REPORTED BY DUGES. BECOMING THE SIERA DE SANTA ROSA ONE OF THE MAJOR SITES OF HERPETOFAUNA DIVERSITY IN THE STATE OF GUANAJUATO.
