Biodiversity of Coleoptera (Insecta) in Lipetsk Region (Russia)

(1) Background: Coleoptera is one of the most diverse insect lineages. Coleoptera species live in many ecosystems around the globe and their role in ecosystems is very diverse. To study the number and distribution of species, lists of species were compiled and then added into the database generation platforms. The aim of the work was to describe the modern fauna of Coleoptera based on a recently published dataset. (2) Methods: Studies were conducted from 1971 to 2022. Insects were collected by different means (searching under the bark of trees and stumps, sifting litter and wood dust, soil samples, caught in the light, in soil traps, window traps, etc.). For each observation, the coordinates of the place of discovery, the number of individuals, dates were noted. (3) Results: The dataset presents data on 2416 species and subspecies of Coleoptera from 89 families found in the Lipetsk region. In total, the number of studied specimens in the dataset was 16,184, the number of occurrences was 6192. The largest families in terms of species diversity were Staphylinidae (541 species), Curculionidae (416), Chrysomelidae (315) and Carabidae (285). (4) Conclusions: In addition, based on the analysis of additional references, 452 more species and 2 families are indicated. Thus, the biodiversity of Coleoptera of the Lipetsk region is 2868 species from 89 families.
