fourteen first state records of 13 species of staphylinidae from hidalgo (seven species), san luis potosí (five species) and guanajuato (two species) are presented. geographical distribution data currently known for each species are included, which were located in the mexican biogeographic provinces. the geographical distribution analysis of each species suggests a correspondence with four distribution patterns, three of them previously recognized in several beetle groups and one more identified in this analysis: mountain mexican component (one species), mesoamerican component (seven species), mountain mexican component-continental nearctic component (three species), and south-eastern mexican (two species). in addition to assign the 13 species to each pattern, other species of staphylinidae and species of several families supporting these patterns were included.
