Onthophagus aureofuscus Bates

Onthophagus aureofuscus ( Fig. 1 ) is assessed as Endangered by the 2017 IUCN Red List, with an estimated AOO of 12–32 km 2 ( Favila et al. 2017b). With the new localities provided by our research and additional recorded localities in Veracruz (Álvaro Hernández Rivera 2018; Arriaga-Jiménez et al. 2018), the AOO remains small (increased to more than 44 km 2), but the EOO increased to more than 27,500 km 2, placing it as Near Threatened. The additional localities in Veracruz ( Fig. 8 ) were not taken into account by Favila et al. (2017b) possibly because the species is misspelled as “ aerofuscus ” in some references (e.g., Biodiversidad de Veracruz Vol. II) or due to an incomplete bibliographic search.

This species is known to occur at elevations between 2,600 and 3,160 m in the Sierra Madre Occidental and Sierra Madre Oriental, in pine forest and pastures (Zunino and Halffter 1988a; Halffter et al. 1995, 2019). In the Sierra Norte of Oaxaca (San Pablo Etla and Zempoaltépetl), more than 350 individuals were collected between 2,700 and 3,213 m. In Veracruz (Cofre de Perote and Pico de Orizaba), it was found from 2,700 m to 3,435 m (Arriaga- Jiménez et al. 2018). According to records currently known, this species has an altitudinal lower limit of 2,600 m, inhabits montane slopes but reaching the High Plateau, and is always associated with forest. It has been collected in pitfall traps baited with dung and fungus. Specimen records have been reported from Oaxaca, Puebla, Tlaxcala, and Veracruz ( Figs. 8 , 9 ) ( Bates 1886; Zunino and Halffter 1988; Zunino 2003). A locality in Durango is not considered here because it is a doubtful record.
