Onthophagus mextexus Howden and Cartwright, 1970

As previously mentioned, Pulido Herrera and Zunino (2007) erroneously established the following synonymy: O. mextexus Howden and Cartwright, 1970 (replacement name for O. monticolus Howden and Cartwright 1963 ) = O. durangoensis Balthasar. Onthophagus mextexus is here resurrected as a valid species.

This species has received recent attention ( Huerta Crespo and Cruz Rosales 2016; Huerta Crespo et al. 2016; Halffter et al. 2018) as an important component for sustainable tropical cattle ranching in the State of Veracruz, Mexico. It is found in cloud, Quercus , Pinus - Quercus forests, secondary vegetation, shaded plantations, and paddocks. It can be found in moderately technified ranches that are surrounded by forests.

The species is known to occur in Texas in the United States of America and Nuevo León , Hidalgo , Puebla , Guanajuato , and Veracruz in Mexico. It is here reported for the first time for San Luis Potosí based on one male and seven female specimens from 20 km W Xilitla, 1600 m, 12.vi–6.viii.1983, cloud forest, flight interception trap, S. and J. Peck (Canadian Museum of Nature collection).
