Beetles attracted to carrion (Coleoptera: Scarabaeidae, Geotrupidae, Hybosoridae, Trogidae and Silphidae) in the glens of Coatepec Harinas, Estado de México, Mexico. Rev. Mex. Biodiv.

The glens of Coatepec Harinas in the southern part of Nevado de Toluca are of conservation concern because of their biological integrity. This study reveals the composition of the Scarabaeidae, Geotrupidae, Hybosoridae, Trogidae and Silphidae of the Coatepec Harinas’ glens, and analyzes their abundance, species richness, diversity and seasonality. Such information can be used for further comparative studies conducted outside the glens. Monthly samples were obtained during a year using traps type NTP-80 baited with squid in an oak forest with some elements of cloud forest. A total amount of 1,513 individuals belonging to 9 species and 8 genera were collected. Silphidae (94.3%) was the most abundant family, followed by Scarabaeidae (4.7%), both of which had 3 species each; the remaining families had 1 species and less than 10 specimens. Moreover, Nicrophorus mexicanus Matthews, 1888 (Silphidae), Nicrophorus olidus Matthews, 1888 (Silphidae), Oxelytrum discicolle (Brullè, 1840) (Silphidae) and Oniticellus rhinocerulus Bates, 1889 (Scarabaeidae) grouped together 99% of individuals. Germarostes Paulian, 1982 (Hybosoridae) was recorded for the first time in the Estado de México. The seasonality was evident, 87.5% of the abundance and the 9 species were collected during the rainy season. The diversity of plants and tree canopy cover, as well as the presence of the stream, propitiated favorable conditions for the 4 most abundant species.
