Onthophagus howdenorum Zunino and Halffter

Onthophagus howdenorum ( Fig. 4 ) was previously known only from two localities in Oaxaca, in two different branches of the Sierra Madre del Sur where they were collected by H. and A. Howden in 1979. The first location is on the Oaxaca-Puerto Escondido highway at 2,150 m, and the second one on the Mexico-Oaxaca highway at 2,350 m, both in oak forests (Zunino and Halffter 1988). These localities are part of the Central Valleys region in the southern part of Oaxaca. The recent collections at San Pablo Etla and Zempoaltépetl in the Sierra Norte of Oaxaca expand this species’ known distribution ( Fig. 9 ). It was collected between 2,200 and 2,800 m in pine-oak forest, shrublands and Alnus forest in the northern and southern mountain ranges of Oaxaca. This species is not found in the arid zone of the Oaxacan Central Valleys, where O. chevrolati and O. retusus can be found. Individuals of O. howdenorum were collected with traps baited with dung and mushrooms during the rainy season of 2017.
