Distribution Patterns of the Mexican Species of Carrion Beetles (Coleoptera: Silphidae)

Abstract Silphidae in Mexico, as in other countries, are a broadly studied family of Coleoptera. However, their geographical distribution in this country has been poorly analyzed. The aim of this study was to perform a track analysis of the Mexican species of Silphidae to discuss their distribution patterns. We used bibliographic and new distribution data of 11 Mexican species of Silphidae to construct their individual tracks in maps of biogeographic provinces. The superposition of these tracks allowed detection of generalized tracks, which were compared with previously published distribution patterns to propose hypotheses of primary biogeographic homology. We record Nicrophorus olidus Matthews, 1888 for the first time in Nicaragua and confirm its presence in Honduras. Additionally, three species are new state records for Aguascalientes, and new localities are provided for seven species. We recovered three main distribution patterns. Four species correspond to the Californian Nearctic pattern, followed by...
