Biodiversity of Staphylinidae (Insecta: Coleoptera) in Mexico

We provide information on the specific richness of Mexican Staphylinidae. Brief comments on the biology are included, as well as the number of species by subfamily and by Mexican state, and the number of endemic species. We recognize 1 656 species recorded from Mexico with Staphylininae as the subfamily with highest specific richness: 386 species. Veracruz, Oaxaca and Chiapas remain as the richest Mexican states that contain also the highest numbers of endemic species. "Genera et species staphylinorum insectorum coleopterorum familiae" and the "Biologia Centrali-Americana" are recognized as key works for the development of our knowledge of Mexican staphylinids. This paper is an update of the Mexican Staphylinidae diversity based primarily on the "Illustrated guide to the genera of Staphylinidae (Coleoptera) of Mexico".
