Onthophagus chevrolati Harold

Onthophagus chevrolati ( Fig 2 ), along with the other species in the O. chevrolati species line, shows recent dispersal in the mountainous areas of Oaxaca (Zunino and Halffter 1988a; Halffter et al. 2019). It is distributed in the TMVB, in some mountains

south of the High Plateau (near Veracruz, Puebla, and Oaxaca), and in the Sierra Madre Oriental between the states of Guanajuato, Querétaro, San Luis Potos´ı, and Hidalgo ( Figs. 8 , 9 ) (Zunino and Halffter 1988a). It is very abundant and has been collected in large quantities between 1,800 and 3,800 m in pine forest, pine-oak forest, shrublands, and grasslands (Lobo and Halffter 2000; Arriaga- Jiménez et al. 2018). To differentiate O. chevrolati from its former subspecies O. retusus ( Halffter et al. 2019) , which is sympatric, there are two main characteristics: 1) the matte black coloration of O. chevrolati ; and 2) the unique pronotal sculpture. The pronotal disk has well-defined punctures and few very small secondary punctures, plus a shagreened microsculpture ( Fig. 2 ).
